the 63 will take you to 133+mph with the correct combo and some boost. The 6776 has been 139 and the 66 S tnetics will go over 140
Has anyone done that with the 63? I used 3700lbs and 133mph and got close to the max hp figure posted by Precision for that turbo. If someone has, how much boost and other details of the combo?
I have gone 126 at 3700lbs with a 63 on a stock longblock. I do not think the turbo was maxed out yet. But I never pushed it any further since I already pushed it pretty far.
I've been considering the 66S.
We've butted heads...but I'm glad to see you've added your expertise to this thread. Thanks Bison.
expound?The compressor is not the limitation in the 3 bolt configuation.
Whats the best way to record back pressure?
i noticed a huge difference between the p/65 wheel and the s/q wheel.leaving the potential power aside you must have a right converter with the s/trim.the s/trim 9 times out of 10 runs the .85 presicion ex housing,while if your alittle tight on the converter with the p/trim you can run the smaller ex housing t/netics .63.presicion .63 etc.both t/netics and presicion don't recommend the .63 housings on the s/q trim wheels.
Damn! Thats impressive! Did the turbo have a garrett housing or precision? .63 or larger?
If its a journal you will need something that goes to 3800 at zero boost/vacuum. A commercially available 10.5" will not couple an S trim under anywhere near its power potentialbison i will take your word for it on the ptc spooling up the s-trim .85.i know my 10.5 lock up 3200 doesn't even come close to spooling it but i am going to try the 9.5.i had no problems with the p-trim,lightning fast with the .63 ex housing,still quick with the .82,but the s-trim seems to be a hole different animal.
