just take it to a track and forget about dyno numbers.

[TexStang06]

All I can say is I rode in it when it was on a break in tune at i think 614rwhp...and it hauled. Whether it made those numbers corrected or not I don't know, but it definately felt like the fastest car I've ever been in. Sam's a cool guy and I don't think he has any reason to lie about the numbers. He can't tell ya'll what it made other than what the dyno shows.

what i get from reading is that he had it pullied for 20... Bought heads and cam and it dropped to 14 psi because of the efficiency of the motor. What is going on with the tune is anyones guess and there could be several hidden factors. Lets say, he has 19.x and now he has 14.7 psi showing. Thats not an unrealistic drop if someone put on some race ported heads that flow 315 cfm

plus it could be std.

who cares

BTW this car needs an AUTO with a 3500+ stall depending on gearing. i would not put a t56 in it if I planned on making any more hp than you already have. Id rather run a 9.90 at 140 than a frustrating 10.8 at 135

Good luck and enjoy

thats a very unrealistic drop hes already said what pulleys hes runing and there is already someone in this thread with the SAME pulley set on a fully ported head cam motor and they have already said its 19 pounds

im RUNING the same blower WITH heads that flow 315 cfm and makeing the exact power hes qouteing at 19 psi with the same head unit and very large cams and huge customn exhaust..


alos you wont gain mph from the auto .. you would lose it but you would also run a faster et.

[s_x_i]

The car is what it is and it made what it made. I can't argue any more points than that... the boost gauge hits 14psi every time. I didn't build or tune the motor, so I haven't a leg to stand on in this argument.

I've given up on this thread... you guys figure it out.

you said the exact same power.... is he running the exact same pulley size you have or is yours even smaller?

he will because he willa ctually put the power down. How many 600 hp KB cobras have you seen trap 128 with the t56?

Actually, it's pullied for 24psi with the 3.5 upper/6lb lower combo and it's not realistic to loose 10psi of boost.

The horsepower numbers are about where they should be...boost is not.
I'm running the exact same pulley combo on the same blower with fully ported heads, cams and lt's...I see 19-20 psi.

Hey don't sweat it ..... you are just going off the dyno sheet you have . Maybe its a little on the loose side and you aren't making the power it shows . Maybe your car is a freak and making more than it should . I've seen bone stock LS1's put down over 320 rwhp while others barely put down 290 . They were on different dynos at different times in different conditions . Which one is wrong and which one was right ? The answer lies in your ET's and MPH .

24? holy crap. Yeah, that is not losing 10 pounds. so everything on his setup is correct, except for possibly a malfunctioning boost guage.

I know the typical loss for heavily ported heads and a stroker will be about 4-6

just a 302 with AFRs and an s trim pullied for 10 psi will put down 430 rwhp at 6 psi almost any day of the week, of course e7s flow like a cofee straw

probly 50 of them they trap in the 128 to 130 mph range when they make 600 rwhp regardless of et


ET is effected by traction your MPH will be relativly constant withing a few mph unless you just do something stupid.

a loose converter auto will run much faster et wise due to the dynamics of the way they work but will show a drop in MPH due to converter slip on the top end

[95 GTS]

I know that. I consider wheel hopping and or spinning to be stupid.

traction will increase mph if you go from not putting but about 60 percent of your power down in 1 stand part of second to all of a sudden a full hook.


if someone else got in your car, Dean. they would probably run .5 slower and much less mph. do you agree?

I can run my car on 19 inch street radials and SPIN all the way to the 8th mile nad the mile per hour is only 1 mph off of what it runs on slicks even though its a full two seconds slower et wise

spining doesnt effect mile per hour all that much.

would they run slower maybee sure but what i mean is if the car is driven well IE no missed shifts etc the mph should be the close + or _ 2 to 3 mph regardless of traction.

Stang13 you agree with 97pony lover but in the same remark you were very blunt to the point where you are making your self "holy-er-than-thou"

I just want to know one thing,........what pulley combo are you running or do you not know that either????

come on man some people just dont wanna do all the work themselves and are told things that they see as true and go from that

it does if you modulate your spinning by providing less throttle.


do you know how many c6 z06s go down at the track at 12.0 at 118-120? you should not use yourself as an example.

like i said IF you dont do something wrong.. and if they are going that low of a trap they are doing something wrong short shifting etc.
