Car was running well until the tranny just let go. Can't say I'm suprised. But it's gonna take a few weeks to a month to get the ATF speed built auto up here from Florida. But at least I can turn the boost up and run some race gas on the dyno.
We ran into some tuning issues and never really got a good tune on race gas. We hit 450rwhp during the tuning session on 25 psi of boost and race gas. For some reason we couldn't get anything more out of her. So we decided to hold off and do some troubleshooting before we go forward. Trying to figure out what the heck is going on. We figured we would lose some more power on the dyno with the built auto trans, but we were making 440-460rwhp in 16-17 psi on pump gas and a stock trans. Thinking we may have to adjust the trans settings in the aem a little more. Car runs great on the street, no problems at all. Just not showing the power numbers we think it should be putting down.
Looking good.....you should be able to hit over 500hp at 18-20 psi on a good tune...Are you trying to keep the auto trans or do you plan on swaping over to r154 or v160 at some point
Ya we were looking for a 550-600 pull on race gas and 25-30 psi of boost. Keeping the built auto trans. Got the billet 2nd gear sprag and upgraded valve body. So this should hold a good 800 plus rwhp. If I was gonna switch id do the v160 swap.
