Re: (tpi 421 vette)
the block is a 408 with forged everything, 8.0:1 C/R, hyd. roller cam, 58mm t.b., the turbo plumbing was pretty "easy" to rig up. A relative of mine who larned the trade in the army helped out. Everything except the turbo's is jet hot coated.
I took her for a spin today and traction is manageable keeping the rpm's under 2500 rpms.

Re: (Speedracer176)
If we do not get the h.p. we are looking for, we may swap in a singlel turbo manifold and ditch the twin setup. I think in some regards its too much for this motor that wont rev much past 6000 rpms.

594RWHP & 808RWTQ
That's all? I really would expect alot more than that.........Just kidding of course (some people get this). Those numbers are friggin awesome! Please send pictures. Who did the CNC porting on the Track 1 heads? I'm looking for a good person to port my AFR 195's currently. I can't find anydoby I like.

Speedracer176 I'm not looking for your secrets, but I've been jealous of the F-body guys and their turbo superram setups for a while now. It always seems like there isn't enough room in the engine bay to do this, but you've done what I wanted to do. :)

Re: DYNO NUMBERS 12/16/02 (Mr. Magoo)
we feel confident in the transmission so back on the dyno we went to day and made 4 pulls.
The best of the 4 @ 20 psi resulted in 662RWHP @ 5900 RPM and an amazing 902RWTQ at 4500RPMS. At 6100 RPMS RWHP was at a amazing 649RWHP.
Its cool to have killer torque, but even with the heavy duty port job on the lower manifold it still cannot support the necessary airflow for more power. All that torque makes me think im going to break a crankshaft one day. We have a 25/50/75 hp shot of nitrous lined up. Its injected before & after the compressed air leaves the intercooler. This will be used on hot days in the summer.

Something's not adding up....plugging your 902 tq into the simple formula for HP at a given TQ yields 773 HP, which is alot more than your quoted peak at 5900 RPM. My Combustion Engine Processes instructor would be quite skepticle...
How about some pics and dyno slips??

Re: DYNO NUMBERS 12/16/02 (Speedracer176)
Does this hp/torque model apply to long runner TPI cars too? Say if I got a friend whos long runner TPI style car makes 580rwtq at 4000 rpms and 400rwhp at 4700rpms would you apply the same formula?
I think what the previous poster was saying is that you posted your torque peak as 902 rwtq @ 4500 rpm ..... which equals
902 x 4500 = 4,059,000 divided by 5252 = 772 HP @ 4500 rpm...... However, he noticed that you had posted 662 rwhp @ 5900 rpm as your HP peak..... but that woudl be impossible considering you were making more HP at 4500 rpm than 5900 rpm based upon what you have posted.
Makes you wonder...
cheers,

He could have 400 rwhp at 4700 rpm..... but his hp peak was obviously well before 4700 rpm.

We have a winner!!!
The h/p forumla never lies!!!
:lol: :lol: :lol:
The car has never been on the dyno....im busted
:cry
Good way to find out who knows what about cars though!
To everyone else who believed the hp/torque numbers, do not be so gulable in the futuer
:lol: :lol: :lol: :lol: :lol:
But the car does exist
