We all would say that the M62 can not be pushed to much more beyond 300WHP but what is the Harrop TVS supercharger capable of handling??? I hope it's past 400WHP or at least 380WHP.

Zach06CobaltSC

It's not as much the m62 as it is the heads/manifold. The m62 does create a lot of heat yes, and is not nearly as efficient as the TVS is, but the engine can only do so much.

I don't have the TVS but my buddy does, and I have been reading up on it quite a bit. I don't believe you can hit 380whp, nor 400whp without nitrous. Power like that on the lsj requires a turbo or twincharge setup.

However I know the m62 is good for up to 285 give or take whp, and the TVS is good for 330s+. I haven't seen to many threads about the TVS being pushed really far however it is great to get over that 300 mark, and keep a nice reliable daily driver with a really simple bolt on.

KillerBee

to reach 400 go turbo or go ZZP twincharge kit

XTC_916

Turbo seems like it is the ****. Is it the same deal for big engines??? Does Turbo beat supercharged on the V8's???

Fully built, 400hp could be attainable. You can get over 300 just with the M62.

XTC_916

Damn to get 300 whp with the M62 your going to need a good heat exchanger. and some crazy mods.

Zach06CobaltSC

Building the motor does not add power. It allows you to hold the power that you are already making. The m62 is a pain in the a$$ to get to the 300 mark, or over for that matter.

The TVS is great to get into the lower 300s and the twincharge/turbo setup is great for anything after that. NOW with that being said, if you are going to build the internals, I recommend doing it if you are going over 350whp. Paul has 411whp on stock internals yes, but will it last is the question, and how long.

Turbo vs Supercharger isn't something I am going to get into. The turbo will make more power yes but it all depends on what you are going for, and what your goal is.

Op, let us know your goals, and we can help you achieve them.

The heat exchanger really doesn't play a large roll into getting to the 300 mark. Yes, heat plays a HUGE factor, but the heat exchanger is just a very small role in the bigger picture. Crazy mods - not really. Just a lot of $$$ and some methanol injection, a really good tune, and hopes and dreams. A 35shot also helps a ton!

But as far as having a built motor adding hp, no it does not. And as far as having the m62 reach over 300whp, no not without nitrous. For having the TVS hit 400 without nitrous, no not so much.

XTC_916

I was intrested in Twin-charging but that seems like the easy way to go. I would like to have a pure supercharged cobalt that will beat most Turbo balt's, STI's,EVO's. What do you recommend? Intense Stage 5 seems like a good avenue.

KillerBee

Yeah turbos normally will always make more power then superchargers

As far as a supercharger beatign those cars with the stock m62

60lb injectors
2.6 or 2.7 pully
heat exchanger
Meth
custome tune
nitrous
full 3" exhaust

Zach06CobaltSC

The stock m62 wont beat out a lot of the turbo cars. Period. Hang with them yes, beat them prolly not so much, especially if they are modded which most of them are.

With that being said, if you want to stay supercharged and lay the smack down, I recommend going with nitrous and the m62, or just the tvs, or the tvs and nitrous.

With the mods listed above, you will have VERY high iat2s, and close to 300whp depending on the dyno. I am already tuned, with 22 degrees of timing on the meth, and will be dyno'd monday. However my dyno is very happy lol.

The twincharge kit is the EASY route, as is the hahn stage 5. The TVS is also a VERY simple bolt on. ZZP makes a ton of power, as does the hahn stage 5. Its basically whatever you want to make really, or whatever the car can hold.

As for going with the intense stage 5, etc. NO. DO NOT GET A CANNED TUNE. Also, going with a custom built setup, is MUCH CHEAPER.

What are your goals, and how much $$ do ya wanna blow?

XTC_916

Is meth like NOS which damages the wears the engine faster??? I am against NOS and if meth is similar I am not intrested. But Intense stage 5 promises 275 WHP thats around 323 BHP. For a thousand dollars. How much cheaper would it be custom??? Under 6000 is what i want to spend.

Zach06CobaltSC

Intense stage 5 can promise whatever they want, but coming from someone who has a lot of knowledge on the setup and the lsj engines, CANED TUNES ARE BAD. Remember that. They don't know every mod you have, unless you only have their mods AND every car is different.

With that aside, dont go canned. Now for the methanol, obviously you haven't done to much reading so that annoys me, but the forums are here for a reason. So I will be nice and help ya out.

Methanol and Nitrous are nothing alike IMO. The reason people use methanol is because it cools down the iat2s and allows you to run more timing, and keeps detonation down.

Basically methanol works like this. You spray a mixture of methanol, or windshield washer fluid into your cold air intake or throttle body spacer. This cools down the charge of the air coming into the motor. Colder air results in better performance and more power. ALSO using methanol raises your octane. With methanol being mixed in with the air, your octane can be raised to as much as 116!

I am not against methanol, nor nitrous and will be running both in the near future.

KillerBee

Meth is injected from your intake it helps to lower your AIT temps which causes you to make more HP. And no they are not the same.

theneelster

You can't do that on a stock engine/drivetrain. Build the car prior or pay the price

Zach06CobaltSC

Methanol alone does not help add much hp. However methanol allows you to run more timing. Timing = hp.

I am currently running 22 degrees on a very very conservative tune. I could probably be running upwards in excess of 25 degrees if not more on a higher mixture of methanol.

XTC_916

That sound's perfect for the heat. I am a new supporter of Meth. But 6000 is my limit what kind of power can I add with 6K??? I

Zach06CobaltSC

Paul is making over 400whp with stock internals, allllthough i think he might be having tranny trouble aye?

XTC - I am assuming you will be having someone else install the stuff. If so, if you really want to blow 6grand into your cobalt, I REALLY recommend going turbo/twincharged because thats how you will make MASSIVE power.

AjSS

If you are willing to spend the money, for under $6000 you can easily go TVS, and all the supporting mods. You could get a very reliable 350whp out of that.

Zach06CobaltSC

Agreed, you can also build your internals up with that $$ to keep it a VERY reliable 350whp.

theneelster

Right...so adding a higher compression ratio piston isn't going to give you more power than original pistons.

Zach06CobaltSC

Oh common, that was a cheap shot =P. <3. You know where I was going with that, you don't have to nit pick at every detail haha. Good point though =P.

theneelster

It's not just a full engine build...you need NEW AXLES and a BETTER CLUTCH.

As far as I know the crank and the rods are good but everything else including the pistons needs to go. You could go billet on the rods which would be better and the only aftermarket crank (I know of) from jpb is insanely expensive.

XTC_916

Twin charge is bad ass and I am really considering it but What kind of power can I get with 6K on a Supercharged cobalt? And yes the TVS will be needed i got that but what power can I get with that blower??? Exedy twin plate cluth will take care of that. dont have to much knowledge on axles??? What brands are there???

Zach06CobaltSC

I am going to say you could hit 350whp with the tvs and a built motor going alll out hardcore. THIS IS WITHOUT NITROUS since you are against it for some odd reason. If you build a motor for it, nitrous is just fine.

KillerBee

with twin charge i know ZZP makeing 580 hp or so and 6k would cover that
