New dyno numbers... Not happy??

Skip the port dude. Get a TS on that ride

This and should have bumped up the compression

It's probably just the Eaton and the fact you were on a dynodynamics (which reads similar to a mustang dyno). your numbers are fine. My ported eaton did 432/420 On a mustang dyno and I put it on a dynojet and made 494/488 on a 2.76 upper only with no changes.

Only think that might be an issue is if the engine builder didn't degree the cams properly that could be a loss of power right there.

There dyno is within 1% of a Dynojet.. IT's not the dyno reading low

like others have said, the stock eaton is holding you back. either get it ported or upgrade to a bigger blower. your going to have to stay upper only as the guys at AED are opposed to using aftermarket lower pulleys. with that considered i would just move to a bigger blower. now, are you worried about emissions? (i dont think you are since you dont have cats) that will limit your blower choice.

So you have this built motor, where do you want to be? HP wise? 500, 600, 700..? That will decide what blower size to go with. To be redundant, open it up.. you should see the numbers.


For now with an Eaton, intake (SBTB, port) and exhaust (headers). If you want to bother.

I will be buying a 2.9 whipple and goal is 800

When you do that get some 1-7/8'' primary LT's and a 3'' X-pipe

Perfect, don't piss around anymore with the Eaton. All it is now is a new engine break-in tool. You are on your way.

very nice. what are your fuel options in sf? i think there are only a couple e85 stations. if you have to stay with 91 i recommend staying with the standard inlet 2.9.

I'm going with the e85 but I will also have a tune for 91oct ofcorse I won't see anywhere close to 800 on 91 but e85 I will..lol I just wanted to hear someone options. Of what u think.

An ported blower would help but a twin screw would better even better

Your gonna need a fuel system if you dont have one yet to run E85 at the power you want. But yes E85 is the way to go for power in ca.

If is a upper only eaton then those numbers are about right even with the motor upgrades. Your A/F is on the rich side and you you could use 2* more timing and you would be closer to 470rwhp.
