Back in Sept 2008, when my 6G74 swap was finished (3000GTs/Stealths have a 6G72 stock from factory), I had Dynojet numbers showing 600awhp/631awtq on pure Pump Gas. After approximately 500 miles/11 months later (Sept 2009) I decided to dyno again on the SAME model/chassis Dynojet and verify/check the dyno numbers. Unfortunately, we were never able to replicate those numbers - or get anywhere close. With the same tune/boost, all we could manage was around 515awhp. Quite frustrating and perplexing...
We ended up tearing things down and found several issues, some minor, some major, which I would rather not get into right now. Over the last 3 months, time was spent fixing these problems and also making a few improvement tweaks as well.
After some short delays on my part, the car was back together again and I finally have the results I was originally hoping to obtain 2 years ago when I decided to do this 6G74 project.
These results could be improved upon, but I had zero urge to "push" the tune or get aggressive.
Pure pump gas (19psi) - 591awhp/569awtq
Notes: Full boost at 3500 rpms, peek tq at 4300 rpms
Pump gas + 50/50 meth/water injection (21psi) - 634awhp/612awtq
Notes: Full boost at 3700 rpms, peek tq at 4300 rpms
Race gas + 50/50 meth/water injection (24psi) - 688awhp/679awtq
Note: Full boost (spike to 27) at 3700 rpms, peek tq at 4100 rpms
Regardless of which tune (pump, pump+meth, race+meth), the power under the curve is incredible. I think we could have hit 700+ by getting a bit aggressive, but it's not worth the risk to me. The E16g turbos are very close to being tapped out but they sure seem to fit this motor perfectly when it comes to useable power.
Extremely pleased with the car overall. I roadrace (Gingerman, Road America, etc.) at HPDE events and drag race occasionally. I might have also participated in a car show or two, heh ;) Tried Autocrossing once, but learned I sucked at it, ha.
I know people always want mod lists, but it's been awhile since I updated mine. The basics are:
Merkel Racing 3.5L 6G74
IPS E16Gs/Headers
AEM EMS
1000cc Injectors
Dual hotwired Walbros
Meth/Water Injection Kit
3SX Brian Crower 272 cams
IPS 4" single shot exhaust
Custom heads/porting/intake valves
LSE instake manifold/90mm TB
SS transfer case
MW 300m output shaft
PST 2-piece CFDS
K-Sport coilover suspension and tuned
Stoptech 332mm brake package
6 point custom cage
... and craploads of other stuff including maybe a few chromed things.
April's HPDE event at Road America is going to be a blast!! Dyno chart is below...
