I'm at 704 whp on pump gas, similar mods although I do have a BAP. My car is an auto and dyno is a mustang. 9.8 @ 139 mph.

Adding the 18-20% loss in the drivetrain, That motor is making over 900HP at the flywheel????

My new setup made 745 on 91 at 16 psi. That converter probably isn't hurting your 1/4 mile times..... Or the DA. I think my posts above are just stating what lots are thinking. Seems abit high for mod list. But it's none of my business!!!

Dyno numbers are great but often can be misleading. One car can have an ice tank, dyno on a 68 degree day with a -1200 DA on a dyno jet with no correction. Another car may have done another pull 5 minutes earlier in weather far worse on a mustang dyno. Its great for tuning but I feel confident if you took all these cars and put them on a dyno the same day the HP numbers for many would change.

Agreed!! Just seems high given no additional fuel supply and pump gas with blower only 30% overdriven. No matter how cold or what dyno. I see most tuners posting up results in the 650 to 690 range with similar mods. This is 100rwhp more.

Do you have an aftermarket fuel system or just a pump booster?

Also, are you still using the stock short block? Your car is running exactly what my goal is.

I'm also interested in you build, if your willing to share some info what cam and converter are you running and what stall is it. Thanks Mike

Interesting thread. I've been following it also. I have a similar build without LT headers that made 100 rwhp less in good air and I am almost out of fuel.

Hey Man, definitely. Do you ever go to the cruise nights at Macungie Memorial Park? Maybe we can meet up some time. It is going to take some practice, that is for sure.

Maybe I missed something, but I would be seriously interested if the builder/shop could post more info in here and offer something to all of us!

Let me see if I can get Mike to give you some information. I think he has an account on here.

I know you are running ported/milled heads done by Jeremy Formato. Jeremy did your tune as well if I am not mistaken?
