Blown 4-banger

Nice HP, but I was expecting more in the torque department. Hell, Paul's got ya beat by 50+ ft-lbs!

We went over this a few pages ago.. haha... Lower compression + cams + big turbo = < Stock compression, stock cams, smaller turbo... haha so yes it was expected

Blown 4-banger

Ha! I stopped readin after the first 20 pages

Very nice numbers gentlemen. God now I cant wait for that snail swap on my car. Bill, I still want to do that custom setup I talked with you about. were these numbers on the meth injection?

Hahn RaceCraft

No sir. Straight 93 octane, nothing else but BOOST!

MVP

That's HOT.

twiztidcobaltss

I dont know if anyone asked this or not but can u buy that hahn turbo kit or have them build it.

Hahn RaceCraft

Yes, we are in the process of putting together pricing for this system, as well as our soon-to-be released Super 20G TurboSystem. If you'd like to get on our update list for information as it becomes available, just email sales@turbosystem.com and ask to be added to the Cobalt list!

MVP

email sent to be added to the list.

AHHHHHHHHHHHHH! Thank F'in GOD! I've been wanting/waiting for so long. I need to beef my savings account back up!

Super20G kit pics to wet your appetite (Unfortunately the turbo just barely hits the frame in the Atom but these are the parts you guys will get for your cobalts, thanks to Bill he is working with my builder to get a different manifold in there)

I'm thinking I wont even add an exhaust - just leave it like that with flames shooting out the back of the car




Thanks to Bill who has been extremely helpful with my Atom project. You guys should give him all your money and buy lots of his stuff

Smarty Art

He first has to have something for us to buy so we can give him all our money.

06noscobaltss

Bolus, THAT IS PURE SEX! WOW! Even I am jealous! That is so sick! Cant wait to see vids of it on the road. Def going to have some flame issues. Hopefully you get the manifold situation figured out soon!

i wanna come up to oregon and tune that sucker!

440.....Don't get me wrong, 440 is niCe, but I must be the only one who thinks that's pretty low for a gt35....especially with cams and built valvetrain reving to 8000rpm....i'm surprised to see that it looks like i'm the first one to say that

Is this a mustang dyno?

luciano23456

ill have to say i was expecting more hp, but i know he is on his way to 30psi+ and race gas so no need for anyone to tell again for the 10000000th time

MVP

remember though hes only on pump gas he probably hasnt added much timing if any at all not to mention the motor will more likely still handle more boost. me personally though I'd stick to adding timing. with either race gas or even better(in my oppinion) meth injection.

memphisr24

Yeah i'm not about adding timing either...I still run the stock timing chart...only time I play around with timing is when I use 100 octane

MVP

I think you read my post wrong. I'm Pro timing. I think there needs to be a balance between compression boost and timing. I dont get the guys who jack the compression way up on a boosted street car for power(not that it happened in this case) i always think, whats the point of even having a turbo charger or supercharger on a street car if your going to jack the compression way up. IMHO if you do it like that (on a street car) your taking away from engine longevity. I could see running mild amounts of boost and high compression but only on a race car.

you said you only add timing when you run race gas. Why not run meth injection and eliminate the need to run race gas all the time? bottom line i think the folks at hahn race craft and o6noscobaltss did a fantastic job on this car and the only way the power numbers are goin on this project is up. I like the idea of lower compression and alot of boost and timing with higher octane fuel.

memphisr24

No, I know what you said. I was just saying I don't add timing either (including hahn if that's what they are doing) I have meth...but I only installed 50% of it

And I can get 100 octane not too far from me from the pump so it's easier

About the compression situation, unless you're going to a full standalone, there's no point to drop the compression because the pcm can only take so much (when it comes to map pressure and fueling etc). I think our 9.5:1 is perfect and i'm staying with that. It's still easy to obtain 20lbs of boost on 9.5:1

Hahn RaceCraft

The thread is soo long now, some finer details are a bit mired, lol! Perhaps you're the first because the others read it all.

Yep, it's 'only' 440 WHP because we decided to just set the high mark for pure pump gas first, then move on to the full output of the turbo with high octane later.

Just to recap for those who'd prefer to not have to read 1000+ posts :

• 440 WHP record was set on 93 octane, no meth injection, no 'just added a little octane 'cuz I was scared'...just real, honest-to-God pump gas!
• That's over 500 engine HP, or more than double stock power output, on pump gas...certainly nothing to scoff at for any 2.0 liter street car.
• The next step (after we get some other projects further along, like the Cobalt 20G TurboSystem) is to put some octane in her and turn up the boost.
• Like Paul mentions earlier, we will then be targeting the 525-550 WHP range, thus realizing the full capability of GT35R.
• It's a Dynojet 224xLC dyno

2K5SS/SC?

Props once again. I hope to be seing some 20G results soon though because I should be getting back late June if all goes well, and my pocket has a hole burning in it with money for a Super 20G, manifold, and the oil/coolant feed & return kit so I can make my own kit! If the 20G is fully spooled by 3500rpms and lays down around 350whp at 20-22 psi I will be a very happy camper! In fact get back to work Bill, no forum time until we get some numbers!

Area47

change the cams and put an exhaust cam gear on it

Rage915

still no price on theses kits, anything? so we have a target number to save?

2K5SS/SC?

Who me? Area, you like the little devil on the opposite shoulder from the angel!

The thought has crossed my mind several times and is always in the back of my head. I just really dread taking the head back off because it's a PITA! You know I'd have to have the head P&P'd too while I was it, along with installing some neutral balance shafts, and then the issue of swapping some forged slugs in there comes into play as well. However, those additions would set me up for success in the future.
