Realistic improvements????? Opinions wanted
Posted 02 January 2009 - 02:58 PM
Its an auto 06 mustang gt.It has Airrade cai and a tune.Dyno'd 268/271 at Jim's
The car currently runs (with me driving) 13.33-13.48 with a best of 13.23.....60' times are around2.10-2.14. It traps 101-103
With Sherry driving it runs 13.45-13.70's best of 13.38 60' 2.15-2.25 at 102-104
Thats on its factory tires with 3.55's.....
Would just changing to my slicks, give it a better time?It spins alot on the 17" Pirellas
Would 4.10's give it much of an improvement over factory gears?
If I was to add a 150 shot with my 15" bogarts and slicks skinnies up front (weight savings app. 70 lbs.), what would a realistic improvement be?
Then say to that add 4.10's and a converter????? Aluminum d/s also
On a another note,would the stock con. and tranny and rearend take the 150 shot with slicks?
I would like to get your opinions on it.

Changing gears from 3.55 to 4.10 will make a big difference with your launch and 60' times.
A higher stall converter will also help with a better launch- at the expensive of some drive-ability and transmission heat- when you're not racing.
To my knowledge- the entire car can handle the additional 150 hp from nitrous. HOWEVER, the main reason I don't use nitrous oxide, it the sudden burst of power that puts severe strain on parts. It essentially shocks many internal engine and transmission parts. Now, if you used a stepped or progressive controller- it would help reduce that shock. But, for the total cost of this you may rethink your plan.
What I would recommend is to determine how fast you want to go. This way you can figure out exactly which parts you need- instead of adding one on top of the other (which may conflict with something else). For instance, you may figure out that you need a 3200 stall instead of the 2800 with the 4.10 gears. You may figure out that an auxiliary transmission cooler is needed for repeated racing use.
Best of luck!
EDIT: I just realized I dug up an old thread.
