K taking things to the next level on my new setup was running a gt4088r with a 1.06ar wanting to make more power this year get into lower time. The car is built for Drag racing like to see some 9s..... was looking at the S372's, do they make a dual bb one? also was thinking about maybe bumping the compression up from a 8:8:1 piston to a higher compression figure car see's more track anyways just looking for some opinions......thanks guys

 

no the borg warner s372 turbo does not come ball bearing non of there turbos do... they are all journel bearing.. as far as raising the compression of the piston .. i would go up to about 10:1.. itll help the turbo lag that your goin to have if you get the s372.. a few of my friends have it and they say its the way to go .. if u have the right setup/tune u should see high 9's... GOOD LUCK

would it be worth ditching my dual bb turbo thats a lil smaller for the s372 or do you think that I could be just fine on that gt4088r

 

a 372 has proven to be better than any 42 series turbo. -from what i read-

 

well it all depends on what your tryin to do with your car... i say a gt40 is good for around 750 whp give or take...if u dont mind the lag and want to make big power then switch to the s372...

but if your lookin for something that makes more power then the gt40 ..with a lil less lag and it comes dual bb go with the new billet PT67 precision turbo... i just ordered mine 2 days ago.. its a great turbo... go in the search box and type in "billet pt67".. theres a dyno graph comparrison on both the gt40 vs. pt67.. ull get all the info you need to know about that turbo i recomended to u..

let me know if u need any more help

correct me if im wrong but i thought compression didn't affect spool time.

 

Well I love the 4088r its badass I have a 1.06ar on it the thing see's full boost by 4000rpms on 10.7psi it never has had any sort of turbo lag plus Im running a full-race top mount twin waste gated manifold to. I wann drag race this car more than just drive it lol its my power monster..... will look into those billet pt67's my wife wants a car now so looking into mocking something up with the 4088r or possibly that pt67
