ManiFold arrived ok...I'm sending him pictures if the engine bay, going thru build threads to get pics of it on and off engine :p it's a tight fit bu doable...and a gb and preorder will be done once the prototype is done...but I'm not a vendor onthis forum so I don't want to post anything as this is a RnD thread, so I don't want it getting locked...turnaround is around 1-2weeks for a prototype

k got the pics, ill be sure to fwd them over to vulcan, also something im planning on working on...genIV/V m90 blower from the 3800 series II/III engine 
they sell for way cheaper than a TVS, and when u combine the cost of the m90+manifold, total cost will be cheaper than a TVS and have better cooling abilities along with better blow than stock, but that wont start until i get my hands on a m90 genIV/V blower...for those who will try and bash my idea, the m90 is a good blower that works well on 4cylinders...and would be a cheaper alternative to a TVS

It's been proven the M90 will not have any significant gains over an M62 because it cannot be spun as fast. Lots of threads on the subject. It's been beaten to death.

I can't find his numbers but it was something like 280 ish to the wheels.

A simply search would have saved you a little brain power coming up with this idea.

Somewhere either here or on RLF i did all the flow and parasitic loss calcs and basically even on a race head and cam ud maybe start to see a 5hp gain over a m62. And that was a m90Gen V...not a m90 gen III like u have. On a m90 gen 3 u wont see a gain ever. On a m90 gen V You may see a gain of 5hp but only after spending 4k on a head setup...and thats still a big if...IIRC u had to stay under 12psi to see any gains.

no water pump, or alternator. 10 hp right here. easy. now factor in the drag from the balance shafts as well. we're down another 15-20 hp. im being generous. humor me.
372 - 20 = 352.
speed density tune on a m-800. there is an easy 10 hp right here.
342
lets stick a trans on this sucker and shove it into a car. now you get to turn the axles. hub bearings, brakes, wheels. lets be generous and use 15% loss
51.3 drive train loss
290.7 whp
doh!
how does this work in reality? not very well in the favor of hot rod mag. i am not going to even try and figure up the drag loss from the failure of trying to spin a blower that displaces 1.9 liters and trying to cram that into a 2.0 liter engine.
290whp can be had on a box stock m62
300+ can be had from the tvs1320 blower.
my math and idea's are no way in any shape or form exact. numbers were merely used for a reference to get real world numbers. use them as you wish

hmm...thats assuming a 2.0l engine, now put in a 2.2 with higher compression and higher displacement...and i have seen quad4's use a m90 and get a 100% increase in power, if not more, the m62 so far has only yielded me about 80%...took me from 129whp to a est 220whp...and thats considering the samller pulley, now wouldnt a m90 make more efficient cooler power than the m62? hmmm...still something im going to work on it...and hood fitment and clearance is not a issue bc this will have a manifold made for just the m90, and im trying to get every ponyout of a sc set up on my 2.2 w/stock engine, so a TVS is not a option, and evenw ith a 2.8 i dont think it will break 250whp...than again only people that have dyno'd have been 2.2 running a 3" neither interviewatruins or hunterkiller have dyno'd their 2.8 m62...once again, its not deffinant, i may change the blower im picking to something else, thats always a option, with a custom manifold, i could slap any blower i thought would be better than the m90, maybe not a tvs1320, possibly something smaller, dont know yet....but for now im stickign to the m62...

By all means.. its going to be a experience seeing how things work... if they even do or not.. and why it works the way it does...
Personally, the more testing.. the more its gonna show against its favor.. But proving something doesnt work is just as good as proving something does...
good luck, i wouldnt mind to see the updates.

yeah i mean it wont be as expensive as it used to be, not with a usable manifold in production, even if its a 1 off manifold just for me, i can have vulcan make it for me ad just me, id pay for manifold+m90...and have a cool different project...i guess im just tired of being a m62sc 2.2, just like everyone else, but i dont wanna go turbo, and having a m90 in th bay would change the look everyone is so used too seeing in the cobalt

here's the progress so far on the ld9 manifold
the eco manifold will begin shortly...waiting for the m62 flanges to arrive so work on it can begin
