So I went to the track again Friday. I have been having a hard time getting traction so I did a little work on the car this last week. Installed new LCA bushings (Kept splitting the bushings last two trips). Added a BMR extreme roll control bar and LCA relocation brackets.
Well that solved my traction issues! The car is dead hooking now!!
We made 2 passes on motor to get the launch right. Then we decided to go for it and spray out of the whole! The car does not yet have a roll cage so we new this would be the last trip for the night! WRONG!! Had a great launch and dropped my 330' by 4 tenths. However, when I shifted to 3rd I missed the shift!!!! AAArrrggghhh!!!
We decided to make one more pass and try it again. The same thing!!! 3rd was gone!!!
Turns out a stock Cobra twin disk clutch just can"t handle launching 660 rwhp on a 5 grand dump with slicks and bogarts (surprising huh). I would have thought the Ford engineers would have planned for this!! LOL
Well this is what the clutch looked like this morning when we pulled it!
It's toast!! But I got a solution for it!!!
That's right we're going to an automatic!! I'll keep you guys updated on the transformation!

Couldn't make a clean pass! We were making 1/8th mile hits to get the launch right. When we went to run it out, spraying out of the whole, it was too much for it!!
The best we've done on the car so far is 11.2 at 127 but we were spinning bad on launch and only spraying in 3rd and 4th.
We will see what the car can really do this weekend with the new trans!

Are you going with a full manual valve body and transbrake? That's the way my car is setup for bracket racing, along with a 2-step. It's like a manual without a clutch and you can't miss a gear. Last time at the track (almost a month ago), car made six passes with 0.098 of a second separating slowest from fastest times. Automatic is helpful for competitive consistency.
Plain and simple the auto is much quicker (shifting) and consistent for the track IMHO and the stick is fun for DD and street racing. Ask almost any truly serious track racer and they will say the same!

Forensicsteve; Exactly! We're putting in a 3 speed racing transmission with a Neal Chance converter and transbrake. The car will be going out to have a compound boost system with twin 60mm turbo's feeding the Eaton put on after the World Ford Challenge. Goes up to Eastexas race cars to have the cage put in afterwards.
MYGT500: You are correct the Automatic is much more consistant. It also keeps the car in boost during the shift normally a whole second can be taken off the time with an Automatic over a manual!

He's running the same "girl-o-matic" I am. I should probably let John Urist (three time NMRA champion and owner of hellion turbo's), Danny Bagginga, Don Burton, Richard Lelsz and 1/2 acre now that their 7 second cars are running on "girl-o-matics also.
As far as the street goes.....I'll give you 2 lengths and the move and still smoke you like your in reverse!

Even with nearly stock cars the automatics consistently put down better times than manuals...its just a fact of life...
You are correct! It's just faster and more consistent. On average a conversion from manual to automatic will cut as much as a full second off your time.

No worries......that car of yours looks nothing girly-like and performance-wise? Pfft!!! You've created a BEAST!!!! I think you could easily give anyone a damn good run for their money!!
So you'll have the new automatic installed in time for this weekend?? This should be very interesting for you track times!!!
Please keep us posted on the progress of that racecar of yours........man, I can't imagine how much fun it is to drive it!!
After reading the article in this months MM&FF I have decided it is the answer to the question no one has asked. Theirs was down 150 something rwhp from running Turbo's alone.
I think just running the turbo set up would be better, but to each his own.
If you are going to do it, why not try it running a compund twin turbo into a 3.4L whipple. At least the blower wont be as big of an inlet restriction.
Also I thougt it was weird the way compound boost..... well compounds. 11psi from the blower and 7psi from the turbo's made 23psi. I am an engineer, I could never put something so illogical on my car .
Good luck with the auto, for a track car you will be much happier.

You cant ask much from someone who makes that type of comments anyway ...
Gl with your project PLstang !!

I cant wait to see your numbers with the automatic!!!!!! I love my manual but damm, sometimes I wish I had gone with the automatic. I think Id be doing much better at the track too!!! lol
Keep us posted for sure!!!!!

Very good question!! Yes I have read the same articles. While a straight Turbo system may make more power that's not the only thing that matters at the track. I could go with a big single 94mm turbo and a 400 cube engine (that's what my race car will have) but this is supposed to be streetable. I really don't want to gut my factory wiring on the car to put in the Big Stuff and all the MSD controlers necessary to make a car like that affective on the track. It's not only about power, but useable power and when that power comes in. The compound boost system appears attractive to me for some of it's benefits on both the small end of the track and the big end. It also lesssons the chance of being "burned down" on the line by a Nitrous car.
I'll definetly let you guys know how the project progresses. I have complete confidence in the people building the settup ( I can't say who at the moment). We'll see if the theory works in practice.
Thanks!!

To each his own. It is a pretty cool set up, just after seeing the numbers I was a little less impressed. It will certainly make good power and the added cubes from the 5.4 wont hurt either.
Just after reading all this stuff about the 3.4L whipple, I am pretty impressed. Maybe you should one up ChevyKiller and put the 3.9L whipple on yours.
