Ok guys, I have read the basics for more power but am lost on some of your initials. I took back my race cobalt and am going to keep it since I cannot bear to sell it for so cheap.

I have a K & N Intake, stock exhaust, Hahn Hi flow DP, as well as the Hahn program and an upgraded FMIC, do not remember the model, those are my power mods. I not believe in changing something because it looks good or sounds cool. Thus I still run the stock exhaust due to changing really only changes the sound not the power.

I was never looking for more power because with the hahn flash the power came on so quickly I really could not use it in auto x unless I was running 285 hoosiers on 11 in wheels on the front.

Now I would like to make a more powerful car. I believe now I probably put about 300 hp or so to the ground and about 320 tq, based on information others have.

I would like to get to 350 or greater hp with more torque also. What has changed since I was racing this in 2008?

Please let me know what to do for mods. I am not looking for peak power, I like power all across the board, but build slower than the hahn program does. I do not want to change turbos if I can help it.

Thanks for taking the time to answer. sorry I do not know what has improved since 2008 and 2009. From reading above it sounds like I am close to having what I need, except for maybe a few minor improvements. Also I want to run on regular pump gas nothing else.

Again thanks for the hep and sorry if I offend anybody by not researching this or that.
I am going to sell my RX7 and Corvette and keep my balt. That is how much I really love our cars.

Again thanks for the info. Also who do you suggest in SW Florida to tune, or Florida for that matter. i will drive to where it needs to go to get it professionally tuned.

Thanks

Unless I am wrong it looks like all I need is the ko4R turbo and have it tuned to be where I want. However I want a turbo that spools just as fast as stock if I can get it. But it appears for the money the turbo and tune is the way to go. Am I correct, or wrong or missing something. I know things have changed since I raced this baby in 2008 and 2009.

It's gonna be hard to make close to 350 on straight gasoline unless you do as you say and get a k04r, but even with that if you don't have 93 octane there isn't a huge bump in power on 91 octane. Getting a different tune on it from the guys who know the cars well, will help. If you have e85 close and that would be a consideration, it would be easily doable. I mix 1/2 93 and 1/2 e85 and still get decent mileage. And you would be in the 340 range on that without going to the r.

The R isn't really worth it without meth or e85

if you have e85 just go that route and blend it 50/50. i made 357whp 375wtq on stock turbo and e85. thats on a pretty conservative tune as well, only running 22psi but its a great working tune and has a lot of log time as well. that tune came from 2 very reputable tuners that arent on here anymore lol.

Like others have said, K04R or E85.
I made 359/418 on full E85, stock turbo.
You may need Opels to run full E85 at sea level; I'm a mile high. Or go the E47 route.
Unless you can't get it where you live, I see no reason not to go E85.

That was great huys. LEARNED ALOT. Big power, fancy fuel. Modest power standard fuel. Fancy ko4r or whatever it is, not a lot of increase unless fuel changes.
You guys r great. Thanks alot.

No one is going to comment on Jeffs Z06 pump? Very interested in the how and why to that one?

He made a separate thread about it but he would need to put more info about it and finish testing

Personally, I would run the Z54 if you are going to turbo swap. I would not waste my time with the k04r. You can surpass the power you are looking for easily, with much more room on just pump gas. Spools quickly and can be controlled with a nice ramp. Very inexpensive compared to other options.

this right here!!! this is the route i will be going as well once i can gather some extra funds, lord only knows when that will be lol. best bang for the buck in my eyes!

In all honesty, the Z54 is still brand new and nobody knows how it will hold up over time. I have to think there is a reason why it is so much less expensive than say a 6758. Cheap is usually not the way to go. Just sayin'...

True. Overtime we will see the durability and how much difference it makes with a journal bearing vs ball bearing. For the price, it seems to be a good buy.

I'm one of the guinea pigs that have one of them. I'm going to give an impression thread after I rack up some miles on it(currently have around 2000, whole bunch of driving these past few weeks).

Inital thoughts? Curious about how it stacks up to the 6758

Tdubbs

I like it. With the journal bearing and steel wheel instead of ball bearing and the titanium wheel it does spool slower, but power seems like it would be on par. When I had it tuned a few weeks back the dyno was down, so I had to go with a street tune. Dave at Pwerks said the flow he was seeing(I forgot to ask for number, too excited) is right around 400whp, with more room to grow. He only tuned it to 25psi on 93, so I'm sure someone running E will see more.

Boost comes on nice and smooth, but I need some headwork to really use it, since I don't rev out past 6500rpm I'm sure there is still some on the table even with just 93.

Edit: As to longevity, only time will tell, but I can't be too pissed if it dies eventually since it's got ZFR power capability for K04R/WR-1 pricing.

Does your car have the flutter issue when you let off that ive been hearing about?

Tdubbs

Not that I've noticed, but now that you mention it next time I drive it I'll pay attention more and see.

I have a used (6758) ZFR kit for sale if interested. It will definitely meet your power goals and spool quick as hell.

The cost cut is in the journal bearings and the steel exhaust wheel. A Precision PT5558 MSRPs for $1050 add ball bearings for another $600.

Tdubbs

Forgot to answer this for you.

It does have mild flutter, but only in very select situations like low boost part throttle. It's not obnoxious in any way. No flutter or surging when you go full boost and let off, or while casually driving, so I think that it's just the typical ZFR style flutter most of those guys talked about, with not much to do about it.
