Two weeks nothin, its been two months lol, first time down was a month, this time is going to be the same. Those shims are .00078" difference, the difference made 2 inch lbs of force change. So I think what I need will be 3.81 if each shim is only 2 inch lbs difference. But it could be linear change with the decrease in thickness so the next shim may make a substantial difference in turning torque. We shall see, Ben is sending me a whole collection. I would have just had one milled but I don't really have much time to work on it anyways so I dont mind just waiting for the right shim.

 

FI is weaksauce anyways, NA tuners are more respectable Come on in, the waters fine.

 

CTSC/AC, gears, and lots of hard driving. No problems what-so-ever.
Problems are not as common as the threads on S2kI make them seem.
Nobody (except a few weird-o's like me) is ever going to post in a problem thread to say that they've had no problems.

Our diffs are more than strong enough to handle a centrifigual blower, given reasonable care and a little respect. That doesn't mean you can't do stupid stuff like donuts, burnouts, autocrosses, etc., because I do all that stuff. It just means that you can't *abuse* the diff while you're doing it.

Naturally, higher boost levels will require other upgrades, but the car handles the centrifigual blowers without problems (based on the experiences of the vast majority of owners running CTSC or VTSC).

IOW, if you want boost and don't go too far with it, the stock diff, clutch, and so on, will be just fine, as long as they aren't abused.

BTW guys, my car was down for two weeks waiting for Comptech to get a resupply of air filters. I ordered a spare, because it was so stupid to be down for so long over such a trivial part.

 

Hahaha. Doesn't take much to make more power with a blower.
BUT, increasing the cars power output is fun no matter how it's done.

 

RED MX5 , Is that a 71 Vega wagon in your sig??
I would love to put an S drive train in one

 

That is a bone stock, like new, all original, 1972 Vega Comback GT, the car that all the reviewers loved so much because of the way it handled. The picture was taken at an autocross back in 1972. Any drive train other than the stock drive train would be a major improvement. The car was a constant source of trouble, but was an effective little autocrosser. Lots of fun going down mountains, but a bit of a drag going up.

I went through all our old pictures the other day, and it was the oldest autocross picture I found. Thought it might be fun to put it in my signature and see who noticed.

You're the first.

 

A Vega is a drag racer dream car, sooooooooo light
We would drop a chevy 350 V8 in just for fun but, if we wanted to get a real rush then a 396 or 427 big block was the choice Ford Pinto was cool for the V8 swap too. One draw back was stoping the POS

 

My uncle had a 600hp one lol, never raced it, sold it. That was the loudest motor I ever heard.

 

Heres an update, and to say the least I'm pissed. So I got a distance collar and two shims but neither were the proper size so I call Ben @ AJ and tell him I need something more like a 3.81mm shim to get the proper preload. Well two months have passed and I have yet to receive anything. The first two weeks aj screwed up and thought they already shipped them out. I call Ben and he tells me he is going to send an email to J's as soon as we get off the phone, month and a half later still sitting here with my my a$$ with no way to put this junk together. So I take it upon myself to take my existing shim and have it milled from a 3.89 to a 3.81 Well of course the idiot I let mill it milled it down to a 3.79 and fubared the first one. So tomorrow I have to take it back and get the last hope I have milled about one thousandth thicker than the existing one in the diff.

 

Well fellas a .001 thicker shim did it for me, I had 12" lbs of turning force and I'll be putting the diff back together tonight and maybe even put it in and yes .001 made a 10" lb difference . We have some nice 43 degree weather today (it was 28 yesterday lol) Then I have to put the manifold back on and break the diff in fully. All the headache finally payed off. I will be posting a full how to install, LSD, Gears and distance collar. Thanks for all the advice from everyone, especially puddydaddy!! He definitely knows his stuff so if you guys need any parts or an install or if you want to build a bulletproof diff you should hit him up.
