If you're doing a custom intercooler, why not use an M90, and get it to work on the series 1?

Because you'd need a CUSTOM lower intake manifold to do it, and nobody here has that kind of money. Custom fuel rail, too. Shorter nosedrive, TB adapter or AFC, maybe both.....that'* a TON of cash.

Put the custom IC between the lower Mani and the blower... The M90 basically has longer rotors/body, and a shorter snout. A custom IC will need some of that stuff anyways. You could even make an adaptor plate between a SS Intercooler, and the series I manifold, and modify fuel delivery, etc.

I havent had the M90 off my Buick to tell if the intake mani area is anywhere near the size of the M62s but it doesnt look like they are even close. By the way the snout length on the M90 is like twice as long as the M62...so im gonna say that doing either a M90 intercooler on an M62 or a full intercooler supercharger swap would be WAY to costly and really not have alot of point to it. on top of that im not even sure that the SER1 L67 would produce the right air/fuel ratio for the M90 blower....if I was a millionair I might try it just to see, but you see im not.

Well if bigger blowers are out of the question, and More boost is, then working with timing after you get an intercooler is one option to consider with a colder air charge.

I dont think more boost is out of the question especially for us 94-95 guys most of us are only running a 2.5" pulley (if they are pulleyed at all) so we should be able to easily go down to a 2.2" for street drving and not be running at a higher blower RPM than the 92-93 guys and we know they dont seem to expericance problems (at least not that ive seen) plus PBs (at least used to when they were up and running) makes pulleys down to a 2.0" so with an intercooler and some high octane I think on race days a 94-95 could even run as low as that....but i wouldnt run it on the street....can anyone calculate an approximate boost level for a 94-95 with a 2.2 and 2.0" pulley......

Im getting about 11 psi now with the 2.5" I would think at least 15 psi+ for a 2.2 and maby 18+ for a 2.0" but I dont know.......dang 18+ psi Boost!!!

OK people major update number 1...I got the SC off the Bonne...so the measuring begins
a couple of questions for the big dogs that know the answers...one in the first picture the big square is the intake tract that the air is pushed through so this is where the heat exchanger would need to go....but those little holes to the outside look like they go to the intake as well...so would they need to be intercooled as well? If so this may be more difficult that I thought. If not then I just need to have someone fabricate a plate that goes over the whole shebang but allows me to put a heat exchanger over just the square part...obviousely the little round holes would have matching holes in the IC plate as would the boost bypass hole on the right and the coolant passage hole etc. The second picture is taken of the underside of the SC as reference. again WillWren....DrJay....you guys know more about the SER1 L67 than just about anyone else here so if you could help this would likely go WAY smoother.

what is that hole towards the front for?

the little tiny one is actually a dowel pin for centering the SC on the mani when installing there is also another one at the back right.....if thats the one you were talking about

sorry, I meant the big one in the center. Its close to the centerline of the manifold.
