Yeah for sure. And not only that, but as has been said multiple times now, the lower heat of the turbo boost would lead to less chance of preign. and detonation which would lead to our pistons being safer.

 

did anyone reply to taht whipple comment im interested? Is there a whipple supercharger that you can buy for the cobalt?

 

not a whipple, but there is a twin-screw.

 

Tag racecraft has been working on a twin scroll blower swap. check out tag's site, or our supporting vendor section

why was everyone calling it the "whipple swap"?

 

i made 260 with a custome tune, bolt ons and a 2.7, ohh and a broken down pipe.
stay tuned for new numbers soon, got a new custom downpipe, retune tomorrow, cooling mods in the next week or so, 300 hp can be achieved with the stock blower, porting the head is definatley a route i will take to get there.

 

 

yea it will help alot. See what i was talking about though... At 10 psi the damn m62 eats up 40 of your chp...you guys run 12 psi stock, and some of you are in the high teens/20ish... say goodbye to 60hp at that point. you made 260 with a 2.7. I can garuntee you would make 300+whp with a turbo setup on a conservative tune and would have less stress on the internals.

 

you seem to know alot, about alot... so, do you think it's possible.. or even worth it to swap in a thunderbird supercoupe blower (eaton)- i know you knew that... it was for everyone else's benefit

 

you mean the m90? It would take alot of work, and no it likely wouldn't be worth it. For all the cost to fab it up and get it working, you could likely be close to the price of a twin screw swap. It may not even fit properly. It is also going to take more to spin that blower, so you are still going to be losing quit a bit of power. Making more...maybe, but it wouldn't be alot. If you want to swap to another eaton you might as well get an mp90. More efficient, and i beleive it is a bit smaller. Personally, if i were you, i would not swap to another roots blower. There is really no point. What you are looking for is better efficiency, and you will not catch the twin-screw on that with another eaton, at least not yet. If you are gonna do all the work/spend all the money, go twin-screw or turbo, not another eaton.

 

not worth to swap in the m90, yes a turbo is a more efficient way of making power, look at outp4ms, 323hp with an exhaust and a stock cooling setup, he was pushing a bit less in the psi range than i was, so take it for what it is, the twin screw should get you close to 300 or a bit over at less psi than what im running thats forsure, our blowers start to loose efficiency around 18 1/2 to 19 psi, im right on the edge of that so i will not drop to another pulley size and start to create power elsewhere, traction should not be over looked either.

and when i say traction i dont mean get the stiffest mounts you can.
1, the vibes will be annyoing to most
2. the vibes WILL cause false knock causing the comp to pull timing thus loose power.
there are a few companies that offer decent poly products, im in the market for some testing of a new line of motor mounts, we will log and see what is too much for the knock sensor.

 

What's your opinion of the Intense transmission mount inserts? They look to be of good quality. I am about to put them on and just wanted to see what you thought.

 

Let's forget turbo, let's say i want to reuse my stock supercharger, I will be using aftermarket internals to achieve the strength rated for higher HP/Compression what parts should i use, from the aftermarket for the internals which are Bulletproof (assuming I use stock supercharger)

Thanks

By the way dont forget I have GMPP STAGE 2 KIT to work with so can i build on that to make more HP, cause I have a never ending lust for Horsepower, I eat, breathe, and talk horsepower. I am new to the cobalt Ecotec engines and from what I drive, and from what I hear this engine is capable of INSANEE Horsepower, but I don't know how to go about getting that horsepower, I know I want and need to upgrade my Internals to take a beating lets start there, Which aftermarket companies offer the LSJ engine Pistons, cams, Valves, Rods, that are strong, and that will be bulletproof.

Thanks

i really don't know why you don't want to swap to a twin-screw or a turbo. Turbo i would understand if you want the responsiveness of a blower or something, but a twin-screw is just all around better in every way than the m62. But if you insist, you are going to spend a shitload more money trying to make huge power with the m62, and it wont be nearly as drivable. You are going to need a **** ton of work if you really want insane power with the m62. I'm talking a totally reworked rotating assembly, not just pistons/rods. Maybe a stroker kit. Head/cams, ported blower, MAJOR cooling mods, etc. Then you are gonna need tons of suspension mods, axles, etc. I hope you know what you are getting yourself into because you are going to probably be upward of 10-11k in mods when it is all said and done if you intend to use the m62 even to make 350whp without nitrous. With nitrous it will be different. If you want INSANE power like you are saying, on the m62...assuming you are talking 400+fwhp...its gonna take TONS AND TONS OF MONEY.

 

Let's put it this way....GMP likes the Ecotec with the M62, yet they do not use that configuration to build a true race car. They always go turbo; and it's not even because of the money (Which they have alot of to play with), it's because of all around efficiency.

I urge you to use a different compressor whether it be twin screw, or turbo (The most cost effective of the two) to make the kind of horsepower that it seems you are referring to. It will still be the Ecotec making the power, just using a different power adder. It almost seems as if you want to use the stock setup because you're afraid that you won't have as much credibility (Sorry if I'm off on that) as if you used a different compressor, when in fact you would be highly respected for realizing the limitations of the stock setup.

 

well, say i use the stock supercharger. Where would i get all the internals from to reach that goal. meaning which companies (aftermarket) make a stroker kit, make good pistons, make good cams ect.. for the LSJ mind you folks i'm gonna go in steps. but it will all eventually lead to that huge horsepower, maybe i might TwinCharge it when i'm done with it

 

as long as they dont cause false knock, your good, do you have hpt or an interceptor?

 

I do not at this time as I just got this car. I plan on getting an interceptor soon, but in the time being I do not plan on launching the car over 2000 or so. But as far as the mounts go they are good?

 

not sure, dont have them, testing a new line of mounts this week with feedback.

 

I need the formula to build a 300 - 310 WHP SS./SC soo lost and don't know where to begin! Heellp By the way how much more HP can I put with $1000

 

$1000 American or Canadian?
