Opps forgot one more thing also remember you are NOT going to have the same amount of high TQ with the Vortech you had with the Nitrous on launch so wheel spin should be less of a problem on launch with DR’s. The car should really come off the line good (hook up) with the 4.10's with the right air pressure in those DR's I see no problem but improvement vs. the nitrous as far as launching and spinning should not be a problem in the first 60' vs the TQ of nitrous before.

 

Thats a good point.. I forgot his launch has been setup using the nitrous and 4.10's.. So yes he will actually have alittle more control because of less torque..

TJ06 is right.. You'll be ok with the 4.10's.. I completley forgot about your car was setup for nitrous previously..

Anyways, the only thing you can do is try it out.. The 4.10's are certainly going to be a huge benefit after the 1/8th mile.. They will probably add 2 to 3psi of boost more on a shift from 3rd to 4th over the stock 3.31's.. With the 3.31's your shift from 3rd to 4th gear @ 100MPH using a 1.41 3rd gear ratio, and 26in tires places the rpm's at 6031rpm.. With the 3.25in pulley this is 10.05PSI of boost.. Now shifting into 4th gear places the rpms at 3558RPM and 5.93psi of boost to start off 4th gear under WOT circumstances..

With the 4.10's you will have to shift at 80MPH @ 5976RPM from 3rd to 4th gear, and end up at 3526RPM and 5.87psi of boost!!


OMG Scrming!! Dump the 4.10's! LOL!! This may change somewhat with the automatic transmission.. But the principle will be the same.. Basically the 4.10's are taking you out of the powerband.. Yes you will probably have the faster 60ft, but somewhere around mid track, the taller geared car is going to pull on you real hard, and you wont be able to catch up by the before he gets to the traps..

WOW!! I never calculated it like this before.. No wonder Powerhouse like the 3.55's!! That sure is an eye opener!!

Now it is understood your 3rd gear may be slightly different.. I just used an example of the situation in my car which is a 5spd manual with 26in tires..

Actually, the unknown will be how much of an advantage will you be at by shifting into 4th gear sooner.. ??? The unknown.. You figure the 3.31 car will be able to run up 20 more MPH before he has to shift into 4th gear.. So the question is, since you shifted sooner, will it play out to your advantage at the traps..

Thats the big unknown.. So its not clear really which is better..

 

Well like TJ said, i think John will be ok. He's got 28" DRs.

 

He most likley will.. I like to calulate it to understand it.. He should be ok..

 

The proof is in the pudding actually.. Bottom line is PHP went 11.65 with 4.10's.. So the 4.10's cant come out.. Its a done deal..

Scrmings all set to run 11's.. LOL!!

I'm still shooting for 12's!!

 

If I get mine procharged,I will be running high tens at 13psi.The power of having a gt and not a v6.

 

And we will all be in the stands rooting for ya, because you are still running a S197 Mustang!! HaHaHa the power of the S197 is awsome!!

Sure am glad I bought one!

 

You have no life, hahaha, you hang out in V6 forums and make stupid coments, hahaha.

 

LOL!! Its all good Jimp! We must show compassion for our brother.. He will come to understand that we are only trying to represent the part of Mustang which makes his V8 passion possible..

He does not yet understand that it is you and I buying a V6, which made his V8 much more affordable for him to enjoy..

It is us who support his dream.. The V6'ers!

 

funny ive seen 2 procharged gt's and neither of them were even running quicker than 12.9 They were only on 10pi, but i can tell ya 3psi isnt gonna put u into the 10s from there. 13psi procharged with a drag setup on a gt might yeild an 11 flat, which is still fast.

 

Cool man...right on...but um, you said "if". Why not just do it and get it over with. Get the procharger! Until then, fiction is for kids.

 

Actually, I like the fact that his parents drive it, not him

 

Hmmm... can't wait to see that!! Hope you have a spare motor.... LOL!

 

Yep, same weak *** pistons as us.

 

Hopefully your parents will let you drive it one day, huh, junior....

 

Convince Mom and Dad to go 13#'s, and make sure to call ahead for the Tow Truck at the end of the block after they got WOT - It'll save you waiting an hour or so on the side of the road for them to pick you up from school
