How much faster will I go in the 1/8th mile with these new MODS?

[1BAD93LX]

My mods are as follows.
Cobra Intake
Edelbrock Performer Heads 1.94 & 1.60 Valves
E-Cam
Mac 1 3/4 Longtube Headers
Mac 3inch Pro Chamber H-Pipe
Flowmaster 3inch One Chamber Flows Dumped
Tremmec 3550 Transmission
24lb Injectors
Pro M 75 Mass Air
3.27 gears
K&N Air filter on end of Mass Air
315/35/17 BFG Drag radials

BEST RUN WITH ABOVE SETUP WAS 8.2 @82MPH w a 1.85 60ft on Street Tire's & 17inch rims


Just did
4.30 Gears
Elimnated the AC with the Ford Motorsport Kit
1inch Spacer
March Ram Air Kit

What Do you think I will run now?

I think you will see almost no change. You will probably have much better MPH but I think your 60ft's will suffer. If by some miracle you can improve your 60 ft's then your ET's will improve a lot but a 17" low profile DR isn't going to help with 4.30's. I have no 1/8 experience but I know what 4.30's feel like. It's a good Combo and would run great on slicks but I think that you are going to find that 1st gear is useless on your 315/35/17 BFG Drag radials. Just my .02 - I know that's not the response that you are looking for.

No I appreciate the honesty, So on a slick what do you think it would do?

That's a different story. 4.30's are a little much for the 1/4 but probably perfect for the 1/8. With perfect traction I think you could see .4-.5 better ET's. .2 -.25 just for putting the slicks on. You could see even more because a 4.30 is way better than a 3.27 for a short distance like that. With 3.27's I would guess that you barely got into 3rd. With 4.30's you will be topped out in third...I think. Does that sound right?

I've got 2.73's and I get to like 3.5k in 3rd gear in the 1/8th.

Well I am going to put a 28inch slick on it, I am hoping to not have to hit 4th gear, So what do you think on a slick & not hitting 4th!

damn it do 1/4 mile! lol

Well, you eliminated some weight form the A/C delete, added more bottom end with the spacer (longer runners) and really gave it a kick with the 4.30's.

I am just not sure if you'll see the true potential due to traction. Throw a 28" slick on there and you'll definatly be in the 7's.
