But by using the question mark on the psi? and guessing that the ?98rwhp is probably 798rwhp = 38psi boost ??? That is purley guess work becasue if your hardware has changed from the 15psi & 25psi figures then it is imposible to use this method (or if the basic hardware will not support the higher pressure ratios "too small compressor map & massive increase in exhaust housing/turbine/header induced back pressure" will all result in lower than expected increases due to loss of Ve% of the engine turbo combination @ that pressure level.)
I am hoping for .....
?05rwhp @ ??psi

I haven't dyno'd it yet and I've done all tuning while driving it. Keep in mind 22psi is on 92 octane fuel....If I ran C-116 I could up the timing and run close to 30psi, but then my T60-1 would be on deaths door at that point....Not to mention 255's aren't gonna stick with 30psi, so I figure less is more in my case....Everyones got there own thang...
ChrisSpeeds car is the **** in my opinion....What an amazing time for a stock chassis RX-7, but then he's running alcohol....Big difference too... anyway, when I get back from Shitcago I'll post the dyno times.....
Any bets on what it will be @ 22psi?

You must really have to retard the timing to push that much on 92...

Relvinnian: Fear not my firend j/k BTW: the car is Vette silver....big difference
My intake temps are very cool and range from 30C-50C on an 80 deg F day...
I won't run 22psi that much or 20psi at that.....My porting and engine was built by the all mighty Kevin Wyum ASP racing and myself up here in Minne....The porting is a somewhat large single port and nothing was really done to the motor except the porting...
Alf/soul 7 ran 25psi on a simular T04S turbo using an S5 motor and had 500 plus hp....before he bridge'd it.... I have a friend from Puerto Rico who is a Wolf EMS tuning god, so I can't take all the credit.... my point????? 22psi isn't sh*t....

I've ran 28lbs of boost. I know Demetrios and Ray Wilson have run over 30psi. Hell, if you add the stress of N2o, its safe to say racers of pushed upwards of 40psi. Its all about winning.
