2K5SS/SC?

That 350whp you speak of was my ultimate goal since day one anyhow, so that would be perfectly fine with me. I can't wait to get my Cobalt turbo'd since I should have done it a long time ago, but it's probably better I learned the tricks with my Integra first. Hopefully my patience and knowledge attained pays off with some nice parts from Hahn.

Oh, and I expect a full review on the BOV!

Hahn RaceCraft

Got the driving report back from Tyler...he's out having fun with the car now at the base 15 PSI, 320 WHP boost level.

He reports "that turbo kit made so many improvements to the car its crazy." To name a few:

• Much more powerful (naturally!)
• Better fuel mileage
• Easier to launch
• Reduced torque steer
• IAT2 after a long haul to 6000 RPM in 4th gear is now 77 degrees...used to be 175-200 with the S/C and 2.8 pulley (he also adds that he tried a 2.6 pulley at one point in the car's previous SC life and was just TERRIFIED of the IAT2 that resulted in!)

Overall, a very happy convert!

2K5SS/SC?

Nice! Why did he go back down to 15psi though? To get used to it? Great to hear, now the question is a little pricing soon?

Hahn RaceCraft

Well, you see, that's one of the great aspects of going turbo...multiple selectable boost levels from the driver's seat!

Even at 'only' 15 PSI, it's such a leap forward in the car's performance from its previous SC iteration (about 70 WHP more!) that yes, he wants to get to know this power level first, then turn it up incrementally. Of course, as a Beta car, he's also making sure the car does everything right at every power level, not just on 'kill'.

We'll ease into the additional reserve power as needed and/or desired. There may be a clutch upgrade involved to really enable the higher boost...the torquemonster is pressing the stock clutch to a degree!

We are working feverishly on website and pricing as I type. I'd say another day or two and we'll launch!

thats amazing...

so with those low IAT2 temperatures would it be safe to say that one could push the stock internals a little farther, specifically the pistons being rated for ~350hp???

2K5SS/SC?

Very true. I completely forgot he is on the stock clutch as well. I'm sure it won't last long though at those power levels.

I can't wait to get my hands on my own 20G now. I think this definitelt sealed the deal. It wasn't the overall numbers that did it because I expected those, it was the power band and torque curve that sold me. That is exactly what I've been aiming for and desiring for my Cobalt. Great work once again!

So what was the surprise by the way for being the closest? Is it still a surprise?

Hahn RaceCraft

Without a doubt, the lowered IAT's significantly hedge one's bet insofar as higher power levels without spark knock problems, and knock (detonation) is what takes pistons out.

So, to answer your question, yes...we can expect more power, safely, and cars like this one and Paul's help prove that point. This one's running 375-425 engine HP, and Paul's been up to about 475 engine HP. In both cases, the engines themselves are stock.

The LSJ is a very magnificient engine once it's not being force-fed by a furnace!

Uhm Pricing??

Hahn RaceCraft

Haha, I was hoping to only pay out if someone guessed right on, but that's almost impossible. Your guess was within less than 1%, so that's close enough!

As your reward, I will hook you up with a discount on a system. Once we start talking turkey, remind me and I'll hook you up. I can't promise hundreds of $$ off, but if nothing else, you'll be able to have a decent dinner with the significant other using the savings!

see posts #74 and #129

2K5SS/SC?

Sounds good. I'll be on standby until then, and looking foward to updates as they come along. Once again thanks for all the hard work, and a special thanks to the tester for putting his car on the line.

Hahn RaceCraft

You are most welcome. Thank you too for the support and interest.

How would the intercooler hold up during road-race conditions at the track (up to 1 hr races)? Would I have problems with heat-soak using your level 5 setup? Would I need to turn down the boost pressures for track days (non-drag racing)?

If I buy your cat-back exhaust, would the piping for the supercharged cat-back bolt-up with the header and down-pipe from the turbo configuration?
Thanks
Eric

i cant wait to see the final product at my door keep the updates coming bill !!

Hahn RaceCraft

The intercooler is BIG. Core dimensions: 4.5" thick, 6" tall, 24" wide, for a total of 648 cubic inches of core volume.

As for setting up the car for track days: I'd say your best bet would be to equip the turbosystem with a low-pressure wastegate actuator (say 8 PSI), then turn up the boost with a boost controller until IAT's and/or coolant temps finally become a too high, or you overpower the track...whichever comes first. One positive aspect of removing the stock intercooler heat exchanger is that it frees up airflow to the radiator, so that's an improvement. I might also tune the cooling fans so they are come in harder at lower temps.

Yes, the exhaust is compatible with the turbo downpipe, and the turbo downpipe reverse compatible with all exhaust systems (3" adamantly recommended!).

hey hahn, what about us ion redlines will it be relatively simple to integrate a cobalt kit into our cars or will you release one for us too? i could be wrong but the only thing i could see being different in the kit would be the tubing?.

Hahn RaceCraft

Tubing would be different, yes, as well as air intake...there's slight differences elsewhere too, such as intercooler mounting, but I bet an enterprising type could start at Level 2 or 3 and take it from there.

So I guess you figured out why everyone is getting the lean spike at the higher RPMS.

yeah that's been taken care of finally.... thank god

and 2K, you'll hopefully have that review tomorrow or thursday, unfortunately I got damn jury duty, so I have to swing past work I guess when I get out.

once again, us redlines get left out, we will have to find ourselves some custom piping and everything $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$. one day hopefully we will get somethingn to help us

06blackg85ss

iTrader: (1)

people will help you, but someone needs to man up and give up there car for a week or so to get it done, I've been offering around here for months and no one wants to do it.....
SO SOMEONE WITH A REDLINE MAN UP AND DO WORK

2K5SS/SC?

Sounds great. I'm really interested in tuneability for the most part and how you mount. A sound clip would be great too to satisfy the "ricer" curiosity side of things.

As for the redine guys, piping should be an easy day. You guys have way more room, and piping is easy to do. Buy some mendral exhaust bends, mark and cut them to size, and if welding is necessary and you don't have a welder go to a local exhaust shop and have it done. It's not that expensive at all. Hell if someone bought the materials and provided me a redline to fit the pipes to, I'd do it for a good meal and a couple brews.

SilverSS/SC

I was fairly sure of the path my SS would take ...the TVS threw a temporary wrench in though . This thread has me back in line . Awesome stuff Bill , cant wait to send some money your way

I wrench on to many other cars to really have time for my own plus Im building a Camaro , so I would likely go with the full deal for simplicty and my sanity . I think you touched on this a long time ago ....just to make sure , the supplied tune wont be locked correct ? I want to explore E85 at some point , couple friends turbo cars are using it to amazing sucess and corn gas pumps are plentiful around here .

does the piping come painted to match?

Hahn RaceCraft

We may offer this as an option. All of our piping is always powder-coated for great looks and durability, and our standard color has always been basic gloss black. Matches everybody, and has a clean, understated OEM-type look. But we are doing things differently with this setup...this may be one more way we can customize it!

sweet, well if your looking to gauge interest, i would be interested fo sho.
