TPI Dyno thread, stock and modded
I've looked around, may over overlooked it but haven't found a thread on stock and modded dyno numbers for the TPI owners. Could we make one to see what people are putting down and with what mods? 305 and 350, list your mods, miles, type of dyno and graph if you have it. I think this could be some valuable information....
I don't have any numbers for mine yet but will soon, just a stock L-98 right now.....

Re: TPI Dyno thread, stock and modded
Thats exactly what I was looking for, thanks!
Like I said in your thread, that blows me away at how much torque these TPI motors make. If we could get them to spin to 6500 while still making power then they would be perfect. So it looks like, from what I've read, its real easy to build a mild 350 with good heads and cam to give a modded LS1 a run for its money. Now I've owned three LS1 cars so I know them very well... but since I have my dream car, a true L-98 IROC-Z... I can't wait to see what I can get out of it.
