I will be putting a blower on my stang soon but I am trying to figure out how much will the stock internals(including Transmission) take before I start breaking stuff. 99% of the time is done off the track. One of my co-wokers has a GTS with 150 shot of NOS and he said that he has launched around 3000rpm under spray about 9 times now and have seen no problems with anything. Clutch still works fine Everything. I am worried that the internals will not hold up. I plan on having 6psi and water/methanol injection. Some Dyno's I have seen measure 410 rwhp with this set up. I am not sure if it was really all stock, but that is what the shop manager said. If you do the calculation of 17% drive terrain loss (found on web) that comes out to 492 bhp. That is a lot for a stock set up. What do you think. Or does all this sound fishy.
