Vengeance Racing/TrickFlow 346 LS1 503RWHP!!!!
Vengeance Racing/TrickFlow 346 LS1 503RWHP!!!! I posted a graph a few weeks back of an 02 SS with TrickFlow heads/VRX1 Camshaft and all the bolt ons... This bad boy made 488/429 ... At the time the car had stock 2002 injectors and a stock fuel pump...
The customer brought in the car last week and we upgraded his pump/injectors and strapped it back down for some additional tweaking. The results speak for themselves....
List of mods:
TrickFlow TFS cylinder heads
Vengeance Racing VRX1 Camshaft
Harland Sharp roller rockers
Kooks stainless 1 3/4 Longtubes, no cats, GMMG catback
Fast 90 ported by Vengeance
Nick Williams 90mm TB
Pulley
Mezierre street pump
4:10 rear with 17x11 rims/tires
PUMP GAS/NO Flycutting/28.5 TOTAL TIMING
The torque impressed us more than the horsepower did!!!! Now this badboy just needs a 12bolt/slicks/ and more importantly a DRIVER

Very well done! 
Most robust torque curve for a 346 I've seen in a long time!

500rwhp is cracked by 6250RPM, in the days that was a good RPM point to crack 400rwhp!
I cant help to think that there is a small correction factor issue, that the max rwtq is more like 430rwtq or so and that the power is exaggerated.
But if its not, damn thats alot.

Awesome job guys, I'm sure the owner is quite pleased, keep up the great work!
Nice job guys- [QUOTE=Ron@Vengeance]PUMP GAS/NO Flycutting/28.5 TOTAL TIMINGQUOTE]
Hi Ron,
Why so much timing?
Do you consider "28.5 TOTAL TIMING" as a pike somewhere on your curve or is it a consistent number between max torque and max power?
Maximum high flowing intake numbers (characteristic of good head) are usually mate with High Volume Efficiency and in my (old) experience of Europeen Racing it induce less timing.
Specially if you can double the efficiency of the head system by adding "increased speed combustion" in the equation of the head enginered design.
Some WRC engines on a 102 ron are using timing pics aroung 16° and their SCR is still not so high, I agree yours is lower...
Do you take any advantage with this 28.5°, is it related to your particular head combustion shape or a particular flowing valve event you decided to use or simply a fact it works better like this?

That torque is rediculous. Every other 500+hp 346 I've seen the torque has been a little lacking due to the big cam. Wanna give a rough estimate on the cam durations? 23x, 24x, or 25x?
What really gets my goat is that those numbers can compete with a big cube setup in terms of peak numbers...granted, there's more to an engine than what it makes peak, but still. These little 346s can move out...
