"When I look at your engine I touch myself....."

Ok you must give more info???

That is crazy, is it suspose to bolt on like that???

Looks like a regular chevy blower but mounted in the wrong spot?

isnt that big square hole for the 4bb to bolt up???


looks cool, where does the air come out???

how much boost?

I am full of question.

what kind of cost are you up to so far???

how much weight does it add???

Can I touch it???

your M90 install is nice, but please dont take this the wrong way. Its better than nothing.

SATURN5

No problems, I know the limits and drawbacks, but this is more for chitz and grinz more than anything. Later I hope to build a 355/383 and add a second M90 and use a LT1 intake. Sorta taking Mikes info from his T-bird and applying them to my Malibu, something different than whats currently appearing around here. cheers, Bob

Looks good man. I take it this means that you're scrapping the twin turbo idea?

B4Ctom1

I see so now your in the R&D phase? cool. I like the twin idea that will be murderous!

that's pretty sweet, i like the idea, keep posting updates

Guido

I thikn that is a great setup!! Add that other eaton and you will REALLY be dazzlin us!

Keep up the good work.

LMFAO @ gumby, hehehe

saturns whatever - where is the compressor intake on that? i saw one of those at the junkyard on a bonneville i think and i was wondering about the possibilities

Trux

is that a supercharger from a v6 grand prix?

SATURN5

The intake is on the back, and it is a Eaton M90 Series 2 off a 89-91 T-Bird SuperCoupe.

Are one of those big enough to feed a 350? It is set up to give a 3.8 liter what 5-6psi boost? What will it give 5.7 liters? 1-2-3 psi? Are you going to change the pulley to up the boost? Any ideas on how to make one of those to work for a draw through carb setup?

mat89RS

MAN, That's awesome, I was thinking about something like that last night, I'm REALLY suprised that you're building that ... I need to know the results.


MAN This is sweet... you ROOOCKKK.


Talk about saving money ! .


Anyway really sweet.

Hum... been there done that. I know that I posted pictures and some info here before, but here is a picture of my brother's t-bird M90 blown LTD that I spent some time last year cutting out brackets and flanges for:



Not a TPI but the same basic idea. It's run 11.5 at 119 with tuning and traction issues.

What size engine is that? You know you'll have to spin that thing to the moon to see some boost. With the stock pulley you'll have enough air flow for about 2psi or less. That one is turning 18,000rpm at redline to make about 7-9psi, (yea, I know, way past the maximum according to eaton's site, but I have some friends on the inside and I can tell you that they get more efficent when you spin them faster. Over 15000 all bets are off, but his seems totally reliable). We also took turns porting the blower housing to see more airflow.

Any other details?

SATURN5

Yeah I saw that pic. Plus Mike's Bird too. I plan to add a second blower later on a better SBC and see what happens. 11.5's... wow! love the sleeper LTD. Hell if this thing pops low 13's I'll laugh my butt off, just a stocker rebuild 305 with a mild cam, fresh 88 heads and a ported intake.. Have a 2.88 first T-10 and 3:50's in the 9 inch. Yeah I hear max is "15K" but hmm from what I have figured with the TPI crank pulley is 16400 blower at 5800 crank. No reason for me to really rap it up, this is just a for grins exercise. Did you port it similar to what Mike shows on his site? How much did you gain? Was it worth the time/effort? thanks, Bob

Actually he's got 2 cases right now, the one that is on the car started as one of mike's ported cases (most of what he did was radiused the inlet port), though I don't know if it was one of the ones that you see on his web site. We did a lot of reshaping, mostly on the inlet since that. The less restirctive the inlet the better, and you can remove a lot of the area around the inlet and with the only side effect being more flow. The slots in the outlet side are mostly for sound cancelation and there is a little to be gained there. If you can get to see the inside of an older and a newer case you'll see that they completely changed the bottom of the case shape to increase efficientcy and it is pretty obvious which way to go with it (sorry, no pics of them).

Right now he's still running older rotors and talks about trying to find some new ones. The newer rotors are epoxy coated to tighten the tolerances between them which is supposed to make them more efficient and build more boost.

Unfortunatly the car wasn't run at the track between cases, but the data logs showed almost 2psi more boost.

Do that to your V6, Gumby.

Gumby

Ive had that idea for many years actualy

Fallen2603

Then do it!

Hell, I'll admit, if I could find a decent V6/T5 88-92 Camaro that wasn't rusted to hell, for a decent price, I'd attempt to do it myself.

Unfortunately, I have too many projects...

Gumby

Well the GF keeps spening my money to be able to pick up a cheap turbo or M90 , beyond that id fab the rest for nutin

Fallen2603

I hear that.

What do you consider "cheap enough" for an M90?

Gumby

Somewhere in the $100-$200 range, I can get a decent turbo for under $200 with a built in wastegate. [save room]

Fallen2603

Found one at a salvage yard about 50 miles from me for $200.

I'll keep me eyes open for one, for you.

Do you have any more drawings, or photos of the brackets you made to mount the blower? I have an M90 I'm going to mount on my TPI 305 C10 pickup, and I'm just gathering as much info and ideas for mounting as possible.
