I give the s4 rotors more credit than most ppl.
The lower static compression (8.5) alows for more boost give the same effective compression.
You make more power from a turbo than you do a motor's compression.
Of course this also reduces the heat b/c turbo's use IC to cool the air where the engine cant' effectivly cool the intake temps when it compresses.
He's got the best of both worlds for hp numbers.
Best intake ports and the lower rotors.

I know that there are some shops out there that do, but I have never, and will never, inflate a hp number in any way, and if I thought for ONE MINUTE that my dyno was reading inaccurately I would shut down that part of my operation until it was fixed.
I was factory trained by Dynapack USA and have been operating this dyno for three years now. I have had *many* cars in the 500 horsepower range that had been dyno'd elsewhere or that came in with engine dyno results, and there has never been any significant variance.
If you want to actually learn something about how and why dyno's differ, I wrote an article about it. http://www.tuxedoparkracing.com/tech...selection.html
Anyone who argues that they can calculate hp from an E.T. more accurately than by putting the car on a Dynapack is uninformed.

What's the hotside on the turbine housing? What about any other changes to the intake manifolds? In your sig picture, it looks like the factory UIM has been replaced with some sort of surge plenum and different TB setup although I can't see it very clearly.

First i want to thank everyone!
20.1 psi on a turbonetics 62-1
850/1600 injectors with twin walbros.
Haltec e6k with hks twin power on 8 month old 10.5 ngk plugs.
8.5 s4 ceramic coated rotors and coated houseings 3mill seals, street port built by rx7 specialties in Canada.
The intake air temps were about 8 deg above ambient and after the pull you could keep your hand on the upper intake plenuim and it was still cool! Ive built a number of shields to keep the motor and water temps cool, and i belive it helps alot.
Ambient was 71.6 in the building.
I want to stat that Steve Kan does not tune 20 lbs on 93 oct, this was just a dyno pull that i had him datalog to see were the car was. Steve tuned the car last year and it was me that felt it would hold 20 psi. basied on the 8 months that i have been running 20 lbs.
I also would not recomend this for anyone else its too close to the edge and i will be going meth injection and run some race gas in the mean time. But i had to know!
I drove the car 250 miles there on bp 93 and filled up before the dyno with bp 93 and then drove 250 miles home getting 20 miles per gal at 75/80 miles per hour.
The car has gone 10.87 at 127 and 10.90 at 127 the 10.90 was with a 10th slower 60 ft time.
The car also is a touring with a/c power steering and working crusie.
I will answer any questions if you dont mind dumb answers! Thanks!

The hot side is .96.
The uip is stock but ported. The greddy elbo was cut and welded to full 3".
Throttel body was ported like everyone does. In the picture you are seeing a cover plate i made to hide the fuel and wireing under the plenuim.
I would try to make myself sound smart but i cant. But when i put all the parts on the car i spent an extreme amout of time trying to get everything just right, i had 5 weeks at night just fitting and clearencing everything before it went in the car. I even had the mateing surfaces resurfaced so everthing would seal good.
I built twin shields on the intake runners between the turbo and down pipe to avoid heating the air. Its 2800 deg with dei and aluminum.
The test is going to be how long will it go before the weak areas raise there ugly head! Almost a year now.
I also change oil and filter every 1500/2000 becouse i drive the **** out of it. I also drain the duel oil coolers, i installed the upside down so they could drain.

Charlie, did you tell them about your gigantic oil coolers ?
FYI: Charlie got to the shop and was complaining about the car's water temps getting too hot on the way (4 Hour Drive). We asked him how hot, he said 170

Gohan (Tony) and myself literally forced Steve to turn the boost up to 25 psi after that, that's when the clutch smoked.
Tony, we aint skeered ! Right !

Interesting. I have the 60-1 turbo with a .96 hot side and I am no where near that mark with steve kans tune. On a dynojet which reads high it pulled 410rwhp at 15psi. Turning up the boost didn't do anything top end.
Is there alot of difference between the 60-1 and the 62-1 turbo?
Well we will see soon with AI when I get it tuned in May what the new numbers will be.

A 62-1 flows about 10 percent more.

I agree, But an ET is insurance and can put you in the area close.
So this is off topic but what dyno reads the highest and which reads the lowest?
I have always heard Mustang, dyno dynamics read the lowest and dynojet the highest. Is this correct?
