Damn those mopar springs were cheap, too bad they dont sell em anymore. Id love to get my hands on a set of the 300lb eibachs but retail is too damned expensive!

IIRC those are discontinued too.
Dont push the red button.You hear me?
Still around but I'd need a used set not new.
Ive seen used sets around $100 every once in a while. I think you'd still be a lot cheaper doing something like SHO front and Cherokee rear from a junkyard or something like that. You can actually mod the rear spring perches to run coilover springs (in the stock location, not around the shocks) which are floating around all over the place.

Right on, ill keep an eye out in the yards for those springs, thanks again for all the help and ill post updates as things move along.
Sorry for the long delay in updates, life sort of got in the way. The weight shedding has begun. Anybody need any interior or other bits? Its not in too bad of shape actually, grey cloth interior. I also have a good radio and the entire HVAC system to get rid of as well. The A/C currently works quite well I should mention so if anybody needs a good working one I would be happy to get rid of it.
Once you get your belt routing done for the blower i would like to see a picture of that.
Dont push the red button.You hear me?
Oh that's been done, it's ridiculously simple actually just used a longer belt and added the blower pulley inbetween the alt. and the upper idler. Cuts the belt contact on the alternator by about half but it hasn't been slipping on us. I'll drawup a routing diagram if you want.
Excellent, that was what i was planning to do for mine as well. I was mostly interested in a pic to see if you had to do anything with the fuel lines.
Dont push the red button.You hear me?
Fuel lines went through the belt, for a street car I'd probably reroute them for safety reasons.
That's enough wrap on the SC pulley that the belt doesn't slip under full boost? I thought I remembered them having more than that?
Still...AWESOME project!
There was a Neon a guy did YEARS ago where they swapped in a 3.0 and mounted the supercharger exactly the same way you did. At first it was an M62, but then they went with an M90! It was MASSIVE on that engine mounted like that! LOL To cover it they built a cowl hood...it must've been over 12"!! It looked ugly, but is supposedly RIPPED!
You pretty much can't get any more belt around the blower pulley then that, its just shy of 180 degrees. I did this more for LOLs then speed, Lemons rules pretty much prevent me from fueling the thing properly, however with some creative epoxy work all of the ports to remove the blower whine are gone so it makes a lovely howl. Perhaps when they value it nothing a few more times I can get away with doing some more work to it, like an extra injector or two on a pressure switch I think. Its funny the blower was 45 bucks, all the crap to make it work was another 200... lol.
I am working on putting a m90 on my lebaron and I am replacing the plenum and making it from scratch I am using a t bird housing and the neck and pully from a 96 riv how fast is that one you got spinning
Im pushing 14k rpm with it due to the sheer size of the crank pulley on the engine. The largest pulley I could find(3.125" IIRC for a shelby cobra) just barely got it to below blower redline at 6k.Originally Posted by carmody87
so if I run it as is I will over rev the blower?
Easy calculation there, Im not sure what the redline of the M90 is. Your crank pulley is 7.5in. So if you divide that by the blower pulley diameter it should give you your drive ratio. lets say you have a 3.25" pulley, your drive ratio would be 2:1. So if your engine redline is 6500, your blower would be spinning at 13k at that speed. Make sense?
yes that dose thank you. from what I found the m90 makes 500cfm at 12k so I think that might be redline
I chose to use an underdrive crank pulley with the stock Tbird SC pulley to bring down my ratio and lower the boost number. Someone in the past (forget who) ran this combo and landed at about 7psi which is right where i'd want to start.
