Forged Performance: Alpha 10 GT-R Pump Gas + 957whp C16
Forged Performance: Alpha 10 GT-R Pump Gas + 957whp C16
We've had the pleasure to work on many of Doug's fun project cars over the years, but this one is definitely the pinnacle of his collection. His car made it back down to us from his home in Illinois after only being back in his hands for a few months. His previous 630 whp setup just wasn't enough to satisfy his need for power. He wanted a true street monster that would wax just about anything in its path while still being a civilized daily driver. The heart of the build consisted of an AMS Alpha 10 setup paired with our FP1-R 3.8L in-house assembled power plant capped with a pair of our FP Spec big valve cylinder heads. With these power goals in mind, several areas need to be upgraded including the engine, transmission, brakes, suspension, wheels and tires...the works.
Many of you recognize our tradition of building balanced track worthy cars that can still be driven daily. When tasked with building a very fast street car, our balanced philosophy is no different. We added a properly sprung set of JRZ RS Pro Silent Edition Coilovers, our Forged Performance Extreme Performance Sway Bar Set with Racing End Links, Endless MX72 brake pads, and a custom spec'd set of 20X10 20X12 HRE wheels wrapped in a square set of Michelin Pilot Super Sport Tires 315/35/20. We even installed a discrete Passport 9500ci radar detector and laser jammer to offer some modicum of protection from the law.
The acceleration is neck snapping while the handling remains razor sharp. Our transmission shifts superbly on the upshift and downshift, responding instantaneously to the paddles. There is a lot to be said for a car that not only makes tremendous power, but can also effectively lay it down to the ground and that's what we've accomplished here.
While we were planning this project, we knew this car was going to be a beast, but we weren't quite prepared for the end result, especially since we consider this a fast spooling balanced daily driven setup. After Sharif worked his magic in front of his Thinkpad, we made an incredible 838 whp @ 24psi on 93 octane on our low reading Dyno Dynamics! Like most shops that use unlinked dyno rollers, we ran the car in 2wd mode in order to preseve the front drive clutches. We were not 100% sure, so we had to confirm with AMS that this was in fact the highest WHP Alpha 10 on 93 octane to date. This car also made 957 whp @ 30psi at 8000rpm on C16 before our dyno gave out. Until we update our dyno software and run larger gauge power cables to the dyno, It appears we are going to have to go to another local dyno to complete the race gas tune on this monster. Stay tuned for updated race gas numbers in the near future! With 5psi left to go, it's no doubt this beast has more room to run.

93 Octane:

C16 Racegas:
You are missing front wheels spinning 
They run car in 2WD.
Not to be an *** to Forged... but most R35's I've seen, were dyno in 4WD. So considering your dyno was set in 2WD mode for that run. You should deduct about 10% to compare this run with any R35's run in AWD.
So:
Pump gas 838-10%=754.2WHP
Let's be generous and let's say 5%
838-5%=796AWHP Pump
957-5%=909AWHP C16
That's your record.
And as far as your "super low reading dyno" argument. I've seen a while ago a GTR that was tuned at your shop with supposedly 500+ AWHP (Access port) and same car few days later was making only 425AWHP on other Dyno Dynamics dyno. (to make it clear owner was just trying to dyno on other DD for comparison)
My car was making similar power there and on any other DD I was on before so I know for certain their dyno was set properly. Which brings me to conclusion that your dyno is only as "low reading" as you want it to be...
And if you want to prove me wrong. Run car in 4WD same boost, pump gas. But post a full dyno file not just graph. So we can see all the parameters, temperature, pressure, correction etc.
Then we'll see how much of a record we have here.
An to put it in perspective:

HKS GT800 on HKS dyno
If you look at the dyno graph from their runs you will see that:
HKS R35 GT800 makes:
- 200ps more at 4000rpm
- 75ps more at 5000rpm
- and same power at 7K rpm that your car makes
Which means that you have accomplished to tune R35 with no low rpm power and torque. Congratulations. I will leave you with this to contemplate...

Someones a little butt-hurt about a high HP GTR!
The fact of the thread is that it is the highest reading Alpha 10 / 93oct GTR to date. And that is exactly what it is.
Nice work Forged!

If what EVO-VI-TME claims is true, then these dyno #'s is crap. Also, keep in mind that Forge is quite shamless with their spam-ing of almost every automotive forum with their junk.
The douchery of people blows my mind. The fact that they would take the time to post it in the other cars section in a non GTR forum means they just wanted to share thier exciting news.
Thanks for sharing the GTR looks sick and I bet it feels awesome
Thanks for sharing the GTR looks sick and I bet it feels awesome
, it's a commercial you ding dong
Then share just the news(facts only) not(our low reading dyno) which is subjective and (record setting) in 2wd might be a record for 2wd. State facts and people will be impressed.
Anyway. Interesting thing, I also responded to them on EVO X forum, however Forged didn't like my comments so much, so they made Admin censor 5 pages of 10 pages long thread, and banned me from forum. For just asking questions, and making comparison of their tune to other cars. Fortunately I saved all missing pages in offline mode before they got "censored".
So nobody can claim that I said something I didn't.
This way they can't make it sound like I was rude or bashing on them.
Back on the subject. If we really need to brag about numbers. Actually I found video of HKS GT800+ which is pretty much the same kind of kit as Alpha10. Video is from jun22 2011.
Compare both numbers and the most importantly both dyno graphs to see how both cars are tuned. Everybody can make their own judgement on this:

And forum is not just a place to advertise, but most importantly it's a place for us to have questions and exchange knowledge.
Am I right ladies and gentleman?
