How many ponies does our 2.0L put out without the SC? my buddy was saying hes going to get a SC on his 2.4L and was boasting that he'll have a faster car than me. I just laughed and said my engine was built for boost and for the price of him getting a SC i can get stage 3 and still have coin in my pocket lol.

 

most def he will make more power then you. displacment and comression over you plus a better baseline.

 

Exactly, if he puts it up to our stock 12 psi, he would smoke us, but then his engine would be smoking in about 10 seconds. The most he would be able to run would probably be like 4 psi which would probably get him up to a stock level SS/SC.

 

Sorry to go off topic, but what heads/fogs do you have on your 'balt, Apex?

 

he will have a faster car than you if he adds a s/c to his 2.4 with a good tune.

 

stock man... i have no idea how they look like that. must have just been the lighting and the input on the camera. if i could find bulbs which look like this i would most def. buy them haha cause they sure as **** dont look like this stock haha

 

Im buying Nokya 8500k heads and Nokya 7000k fogs, and I bet they look similar to your picture if it helps at all

 

awesome man, can you pm me pics when you get it up, if i like the look ill most definatly buy em!

edit: so.... does anybody know what our 2.0's put out?

 

Well, since its low compression, and the displacement is smaller than the 2.2, if you took the charger off, i'd say in the range of 90-110 hp

 

what?! no way i would be thinking 130-140.

My 1.9 L saturn was 124hp and the supercharger kit for that only pushed it to 160 hp. Granted that engine isnt meant for boost...

 

Your 1.9l saturn was meant to be N/A, so it was probably higer compression than your 2.0

I highly doubt that the 2.0 would push 130-140 which is damn near the 2.2 which is tuned for N/A and has higher compression, I would be suprised if the 2.0 ran more than 115hp without the S/C and stock rods and pistons

 

buddy put blower on his 2.2 cavy and i spanked him very badly, his is a complete tube chassis, it was a strictly show car setup with bags and all sorts of stuff so its light, and it was ugly when i raced him.

 

True but remember a supercharger won't yeild a 100% gain, on most larg displacement engines your lucky to see 80-100HP out of one, on a car making 300-400HP already it's only about a 25% gain.

So that said, the 2.0 without the SC is probably around 130-150ish..remember that the 2.0 is also a newer design than the 2.2.

 

We need to ask NJHK, he's the master of ecotecs anyway

 

Yes, the 2.4 is a bigger motor with higher compression. If he just puts a supercharger without an intercooler, he's only going to be able to boost about 5psi before seeing KR-more than likely. He still will not make as much power as a stock S/C 2.0. Remember the 2.4 twin cams? GM makes a supercharger kit for that and it only adds 40 flyweel horsepower with 4.5lbs of boost. Even though it's a different motor, the results will be similar. If he adds an intercooled supercharger, he should be able to run 10lbs, which would obviously make more power. A stock 2.4 dyno's what, ~150whp? He would probably be real close to a stock S/C SS, making roughly 215-220whp. We can only assume since we haven't seen any real results. I would think it would be a close race, but I still give a slight edge to the 2.0 S/C. Add even a GM stage two, or any of the INTENSE stage kits, and it's over for the 2.4. I'm curious though, so let us know.

 

I disagree.
The LSJ is 2.0 liters of displacement with a 9.5-1 compression and a shorter stroke
The L61 is 2.2 liters at 10-1 with the longer stroke.

The difference in displacement between these engines is purely a function of the shorter stroke crankshaft. So, exact same combustion chamber diameter, longer stroke, higher compression, the L61 wins. At 145 HP, the LSJ normally aspirated has to be less, and I would estimate it at around 120.

I am currently running the L61 with a 8.9-1 compression, and while I haven't dynoed it to give an exact number, we estimated it was making 120HP after we finished it.

 

so why wouldnt they just sc the 2.2L for the SS/SC models?

 

They did, they just shortened the travel of the piston to lower the compression ratio, but in the process they lost 200cc of displacement

 

LOL

I'd have to agree with Halfcents post...I think he's dead on.

 

none, it won't run. the ECM will shut it down.

Guessing by higher displacement, i'd say that the stock SC blower on the 2.4 will yield about 9-11 lbs of boost over ambient. i'm thinking that with good injectors and a well tuned set up... you'd prolly get about 240hp at the wheels and just about that in torque.

 

True, two NA engine with the only difference being compression ratios, the higher compression would make more power.

So the LSj without the SC is probably a bit less, but the point is moot as the LSj is supercharged. and and the 2.4 can't handle the PSI that the 2.0 runs. if anything I would say they are probably around the same HP. The LSj can take more PSI, and the 2.4 has the larger displacement.

 

Here are some screen shots from the Street Tuner Challenge on Speed channel.

 

Ok, if we are going to now change the discussion from what an LSJ can do normally aspirated to what a LE5 can do forced induction, then lets try to keep this logical. The Hahn Racecraft LE5 turbo system for the soltice produced 250 WHP at 9psi intercooled. That is a real world result of what it HAS done.

Further more, what supercharger is he gonna bolt on to his LE5? I'm not aware of any such product? Is he just gonna take a GMPP Eaton M62 kit for the J-body ecotecs and bolt it on his car? Tell him good luck with that for me, will ya?

 

woot for joe's crystal ball dynometer.

 

Yes, but that was a turbo. He won't make that much with a supercharger, parasitic loss will keep him from doing so. At that same 9psi, he'd probably only make ~220whp. You really can't compare turbo results with supercharger results, they're not even close. A turbo is far superior in terms of power, less created heat, etc. However, +1 on what supercharger will he use?
