Final Dyno Nos. Looking Very Good!!
some of you may recall my recent posts concerning the loss of torque i experienced and not hitting the numbers i had hoped for with the install of my new cam. there was even an indication of a possible problem with the dyno pull since my peak torque was coming in at 5600 rpms. well since then i have put 500 miles on my car, gone through several heat cycles and been back to MTI Racing for another dyno run and final tune.today they invited back to watch and i just returned with the results.
i am very pleased with the results. 472/437. please take a look and let me know what you think. please note, this is with 3.90 gears..
tks, dal

Remember two things. The numbers are std. A Z06 runs 450 rwhp sae. I'll add a third thing. Driveline loss, even with mods, is still around 55 hp.

hmmmmm,, well then hopefully i can still at least run right along side a stock Z06.. that has been my goal all along. to have the same performance, save 20k and best of all,, do it stealthy.
i hope you do not have any more numbers or things to add that are going to take that away from me.

55-60 RWHP is lost through drive train losses. Yet when I talk to NON CF
folks I give them the Dyno reading + 60 RWHP. If I have 450 RWHP and they ask me what ya got in there I weould say a little over 500. Sound right ?

other members with much more experiemce than me may have different numbers. so i would have thought a car making 450rwhp would be making approximately 530 hp at the crank.

Glad you are finally happy with the results. It would be interesing to see the SAE numbers if you ever get a chance, but if not you have the car running the way you want and that's what matters. Don't get too caught up in trying to back calculate rwhp to bhp. It's a futile effort with no exact science to it. Good luck with the Zs. You should be able to scare a stock one but don't take them for granted. The 427 power curve is killer.

The midrange torque is killer on the Z. Even after they shift they can still be making about 400 HP if the driver takes advantage of the 7000 rpm redline. His gears should help even the score, especially if the Z forgets to downshift as far as should.
