There is deff more power down low but still thats how a k20 is. Thats why they rev out to 8400 stock. And vtec kicks in a 6000. Mine kicks in at 3200 tho, so that helps.

I dont want to cause an argument, but i prefer usable power before 6000rpm. I think most on here will agree.

Yea power every where is nice lol.

Im not one to argue if both sides are understanding of the good and bad of both set ups.

Again thats y why when we get tuned the vtec gets bumped down to 3200. I feel no lack in low end power.

Also i get thru rpms faster then you guys so i get to higher rpms faster so there is less of a time lag. But yes k20s love to be high.

They have the gearing to easily be in their powerband most of the time. Very close ratios.

someone was asking about the power/torque curve. doing a high gear pull shows how it responds. now in ur video i THINK u were in 2nd at about 3000 rpms when you started... and it took off very nicely!

Ok heat exchanger is a general term. Turbos use a air to air heat exchanger to cooler the charge air before the throttle body. An aftercooler cooler is a specific upgrade mostly used on superchargers. It used a small air to water heat exchanger that sits under the supercharger inside the manifold. Then the water coming out of that heat exchanger is cooled by a larger front mount heat exchanger.

This is what it looks like under my supercharger

No i was at 70 and i dropped to 3rd and got to the very bottom of 5th. 6th starts at 137 mph.

Thats what SS/SC have, its just different. It uses laminova cores, much like the intercooler, which water passes through and then is pumped to a larger FMHE. The problem is the laminova cores can heat soak quickly due to them being stacked on top of eachother.

Mine has zero heat soak it used a bell core that is 3.5 thick. 3-5 gear pulls put my iats to about 130 then it drops back into the 90's in about 3-4 sec's.

Your setup shows that with a free flowing head, high rpms, and the proper supporting mods you can make great power with an M62.

The problem with a lot of our members on here is they give up so fast on the M62, because they can't "easily" get to 300whp+ with the stock head, cams, etc. Our head stock does not flow as good as the K20 head stock.

If they were willing to build their setups properly (ported head, cams, nb shafts, etc.) more people would be making decent power with the stock blower.

I think we can learn a lot from your setup, and should pull together and share knowledge and information.

Once again, I thank you for bringing useful/good information to our site.

It seems the way you have it, it is much more efficient. However...the blower on the SS is a Roots blower, and the intake manifold is where it compresses the air. Is that a roots or Twin screw? i may have missed that information earlier, and if so...I apologize in advance

Thanks a lot man!!

Yea honda made it way to easy for us to make power.

CT stage 2 kit and good i/h/e and you have 300 with a tune.

Yeah, that's pretty impressive.

I've been sourcing out a rare GM Racing exhaust ported head for my car.

Once I find one, I'm installing S2 cams, valvesprings, bolting it on, and having some fun.

I have a slightly different M62 blower on my car than the general Cobalt crowd, and it helps create a bit more power.

A ported head will really make it shine

gotcha. wasnt sure how it differed from our intercooler / heat exchanger system. i have no clue what the laminova cores look like, but i really like the system you have set up. very cool. i hear that the laminova cores we have are not as efficient as other aftercooler set ups... kinda sucks.

Our Laminova cores are fine, and do a decent job at removing heat from the charge air.

Although, an intercooler such as the one the OP has might do a little better at cooling.

Yea my aftercooler is a small version of what SVT Cobras use with the blowers they use. Works very good.

I might even have something up my sleeve for you guys. Have to talk to my boss.

Remember lowering your iats will also lower your psi and make it easier for your engine to handle more CFM.

(psi is bad CFM is good)
