power adders

[Dr.Buick]

what power adder would you have? and would it be carb or efi.

I have both a twin turbo car that is efi and a procharge car that is blow threw.

I love the power of the procharger no waiting, but man does that turbo car pull hard. so I would have to say turbo car. with efi

[Mr Twigbert]

Turbo is free power so it is hard to beat that..

[Inspector13]

I run nitrous on an EFI car and that is pretty fun.



So I'd say an EFI stroker motor on spray. :banana1:

[twicks69]

Turbo EFI for me.

Otherwise, twin-charged EFI would be fun for the best of all worlds.

[BAD LS1]

Turbo's arent exactly free power...

76mm's of PTE stuffing my EFI LSx with pressurized atmosphere here.

I wouldnt do it any other way out of all the combo's i had.

[xxtremeteam]

well for my mustang I would love a stroker with a supercharger and EFI but I do not have a money tree so its just a dream

MY mailibu engine was a 421 cid and when I sent it to kenn duttweiler he said the less cubes the better forced air works so no it is a 293. with a f2

[xxtremeteam]

I was thinking somewhere in the 331 range and a blower but this will not happen

[Dr.Buick]

is that why those outlaw drag radial cars have small engines... oh wait...


Carb'd LSx on Nitrous ;)

[Dr.Buick]

[quote=Crawlin;497867]is that why those outlaw drag radial cars have small engines... oh wait...


I really have no idea. I do know that kenny duttweiler is the man for forced induction, and when I sent him my engine I told him to do what you do, no questions from me and i dont care what it cost. I had this enginge out of my bu 3 times last summer and never made a full pass. I will never have a engine built in wisconsin again. This is the 4th enginge kenny has done for me and I have never had a problem and they last forever. (so far)

[BAD LS1]

Is that some kinda "2jz, no shit" motor? I think that can take the cake as "too much CFM" A rolls royce Trent engine aint got shit on that mother.

[0TransAm0]

i don't have a power adder yet... but i would like to toss a maggi on top of my ls1. one of these days...one of these days...

[Voodoo Chick]

Big-ass supercharger for sure.

[Mr Twigbert]

What ever power adder I can afford is the best one for me..

If I could afford a TT setup then I would do it.. But, for now the the lil'ol P1SC will do..

This seems kind of odd, I think boost works great with 400ci. :D

I agree with Tom also! Out of all the setups I have had, the turbo takes the cake for me. (With a carb of course!)

you are right boost did work great on the 400, but works better on a smaller cube engine. If you want to call kenny and tell him he is wrong go for it im not.

The way he explaned it is if you have a turbo that flows 700cfms of air and you have a bore of 4 inch or 3 inch it will make more power and pressure in the smaller one. and i am probley wrong on how i am explaing this.

That makes sence. After the mixture is lit, the pressure wave pushes the cylinder down the bore, the pressure on the piston will not drop out as soon nor as fast because of less space to expand into with the smaller bore. keeping the cyl pressure as high as possible through as much of the downward travel will increase the leverage on the crank through the rod and make more torque/power.

I am not trying to call you or him wrong, it just seems a bit odd. Seems a lot of the top racers today are using big cubes, upwards of 400ci, and gettin' r dun. (Unless of course a class has a ci max)

If it works for you, then more power to ya! :thumbsup

[BAD LS1]

IMO 400 CI or less is not considered BIG hahah But whatever it is about having it right around that 400 ci goes together like peanut butter and jelly for FI cars.

kenny's car is going 6.20s with a twin turbo 293 cid sbc he can build what ever he wants/ I with my pictures would fit to down load i have some cool ones of is builds.

dont get me wrong about my shit i was suprised too. Its a 293, bryant crank, oliver rods, cp or ce pistons, bulliet cam, brodox 18 degree heads spred port, jesel pro shaft rocker arms, and a f2 pro charger this thing should rock:flipoff2:

[BAD LS1]

Maybe its the rpm spinning potential of tiny cubes that make it work? From my own experience i upped mine 20ci to 364 and it was night and day diff on the same boost. Again nearing twoard that magic 400 mark haha

you might be right. Look at smokdu car its a 347 with a f2 that thing went 8.4 thats hauling the mail that is a smaller supercharger than the t-bird and 200 cubes less. grant it thet-bird was .5 sec faster.

I'M NOT SAYING IT'S ONE WAY OR THE OTHER, POSITIVE OR NEGATIVE...

JUST SAYING IT'S NOT A GOOD COMPARISON.

it's like saying that dude's Imp is going the same e.t. on a small 275 drag radial in a 1000lb heavier car on a shot vs. mark's big bad blown lightweight fox body car and a newer 4link design vs. some old 60's suspension technology.

comparisons just can't be made :)

The major difference is that Jims car went fast more then once!:rolf

So in your theory, Jim's T Bird could go faster with 300 less cubic inches on pump gas?

[FourEyedFord]

I love my spray..... i have a turbo setup that i am peicing togeather..... but spray just hits sooo hard on the street..... any any nay-sayers about spray are fags, and most of them have a N/A car anyways..

[BAD LS1]

spray is cool no doubt, but a proper tuned/built turbo car pulls like a spray hit all the time and each gear feels better and better. i had a 200 shot on my car and that feeling faded once into some higher rpm's the turbo yanks all the way to red line.

[70 cutlass 442]

/\/\ you are 100% correct..... but in reality there arnt to many properly tuned or setup turbo cars running around.....

i agree with that.a light shot does feel like it falls off on the top of the track

[Breecher_7]

Turbo or twin screw blower, both are fun as hell to drive.

[scaleracer]

I would like to add what is the cheapest/best route to go?? They all have pros and cons but discuss..

[BAD LS1]

i will add that the turbo cars are a bit more... whats the word... peaky? like the boost comes on all at once and its hard to modulate that to keep the tires on it. where a PD blower or a centri you can pedal it to a degree, spray... well its on or off too, usually resulting in technicolor intake removal too with pedaling hahah.

[PureSound15]

I don't know that there is a cheaper or a best. Real cheap could be a nitrous set up ... best would be a combination of your choice.

I'm a turbo fan... something about that sound and feeling is incredibly addicting.

[BAD LS1]

nitrous is cheaper by far initial investment, but if you wanna go big, your gonna pay for the all the parts to support the shot wanted and bottles go empty FAST on big shots and are 40-50 to fill each time.

[Smokey1226]

screw that, give me a big block NA and ill keep up with most.

[DR.FORD]

I do not believe I could have made 1800HP on pump gas and supercharger with a small engine, neither does Morris-that is why his best combos with a Procharger are 572" Chevrolets. My 572" Ford just out-performed his comparible Chevys. Call it dumb luck because no one has done it before? The winner of the Dynomax PTTW competition was a 600" Ford with twin turbos- on Amoco 93 octane and a very basic tune.
And for the comparers, my junk is 3600 with driver.
Another thing, do you REALLY think with the knowledge and parts available that a ladder bar car has an advantage over a stock-style fox body suspension that has been "worked on"? I'll let you know first hand, but I think not!!
Then again, I don't live for this-I consider this fun!
You all have really cool stuff capable of more.
I guess my motto is I did well not thinking about other peoples cars, instead I thought about doing the best with mine. Nothing worse than losing the fight before you enter the ring!

OOOHHH-pedalling BAAAD!! There will be NO pedalling:headbang

Oh, sorry! I think everyone knows what I have, and I choose to make the best of it because every combo has strong and weak points. Lets see you not respond to people talking about your car. I like to clear the air before it gets out of hand. Looking forward to seeing your X- sounds nice!

[Reverend Cooper]

I for one think jims car looks ******* awesome and runs fast as shit,if your gonna go fast you gotta look good doing it. His car accomplishes both.

[sloLs1]

ive been through them all... N/A, blower, nitrous, and turbo.... they all have their own perks. It really depends what your looking to do, Daily driver, weekend worrier, or straight up drag car... usually you can accomplish all those with a turbo!!! BUT what do i know, i drive a friggin saturn!

[scottie K]

Iv been a nitrous freak for long time,,, but Id rather be forced induced ... ..... it dont matter ...I think if you have enough experence on what ever set up you can make it fast!!

[70 cutlass 442]

I would like to add what is the cheapest/best route to go?? They all have pros and cons but discuss..

Welll. Spray is cheap up front... and for a small hit on a daily driver or just somehting fun on the street on a street car that would be the best dollar for dollar HP investment..... I had $350 into my whole wet nitorus kit, and about $50 to fill the bottle... the bottle would last me between paychecks so it worked out... but i only sprayed when i had to... you wanna go fast then hands down forced induction..... but then you are talking a ton of up front investiment.

[HY35F2T]

[WilliamZ]

I liked Nitrous but it's gets expensive going through a bottle every weekend. I don't have any power adders on my current cars but someday the Z will have a TT setup.

That's how I looked at it plus if you have to build the motor more for spray.. We were gonna get a kit for our Mustang but decided against it because of always having to fill bottles and you would have to have more than one.. But all of it costs a good chunk of change and since we're budget racing it won't have anything for awhile..

Having a good boost controller makes ALL the difference! Trying to take a limited tire turbo car down the track with a manual boost controller is nearly impossible. (10 second ET and faster cars)

I have the AMS 1000 on my car, and it uses 6 stages of gate pressures that you preset to control the hit and get the car down the track (Using either manifold pressure or CO2 to the top of the wastegate actuator). You can control how long each stage lasts down to .01 seconds, and even the rate at which the pressure is applied in each timed stage. I think you should hook one up in your car Tom, and cure those traction issues! :3gears:

Going from a manual controller to an electronic one so far made a huge driveabilty difference, pretty much spools with my foot on the street and has torque out of boost now. so something was goofy with how that manual jobber worked. It has similar features with controlling how fast it comes on but its not as fancy as the one you described.

[Waver]

this is my ideal setup, and I would like to do this one day (had the bottom end and the heads, but I sold it) 351 dart block, 4 bolt cleveland main, 9.5 deck height, dart heads, bored over .40, 4.10 crank, eagle rotating assembly, fuel injected, trick flow r intake with a 90mm tb, with a twin 76mm turbo set up asnd a 100 shot of spray to help spool it up.....

This might not work out at all, and I think my math might be a little off but a 428 tt setup with spray would be cool.

How many diffrent engines have you done over the years before you spent the big buck and built one like you did? My malibu engine has been apart 3 times last summer because of an engine builder. And now it is by someone I can trust. and he used the parts I had. Witch was a block and heads, intake, headers, and carb. And I remember takin to you and ron about this before i did it.

I am NOT making fun of you at all!! Duttweiler knows his builds and combos and if that works for you that is great. I also know Duttweiler is a businessman, and so is Morris. They BOTH will want to sell you on what they know best. I gave Morris the opportunity to do a big Ford of which he had little experience, I just had faith in his abilities. Just be careful in comparing everything to what Dutty says, it may not pan out. You are a good guy and I respect your stuff, and I am sure what he built for YOU will work well for YOU.

Haha, I am just giving you sh!t.
I hate to say this, but sometimes , not always ;), its true. If you are looking to break records in a class, then a turbo car is for you, but if you are looking to be consistent, then you want a blower car. Obviously both go fast as hell, but the blower cars seem to be more repeatable at what they do.

A lot of it comes down to the tuning, chassis and engine, and of course whatever you are more comfortable with. I'm sure you guys will make stupid power with the F3, I was just hoping to convert another one over to the dark side! I have had Andy in my sights for a while, and I can tell you, he has changed from saying never to maybe in the future for a turbo. :wow :D

Jim thats a common issue as of late for GM update flashes with techII's. Gm has not been able to remedy the fault yet. It doesnt matter if its been tuned or not by an aftermarket program, its a fault in the GM software and it locks the PCM, usually not letting ANYTHING back into it. People were all scared thinking GM was purposely locking the computer when its not true.

This just affects the ECM and TCM not the body or bag computer....
