procharger vs. powerdyne

[Ironman24]

Stefan, you trip me out with your issues against nitrous. I bet the fellow Powerdyne users DO care what the car puts out with nitrous. (powerdyne owners speak up your opinion here)

Here is why I think so... Of course I ran a dyno pull with no nitrous, but only one time because it ran so lean. Results were 284/310. Right around 50hp less, hince the 50 shot. I think the nitrous offers a great intercooler option for the Powerdyne users that don't have one. With tuning I know the combo could produce better results, no question there. Just look at my A/F ratio on the dyno graph, it's all over the place mainly due to the lack of FMU.

pgriffith - My Powerdyne is already sold to another 98 Camaro.

lets not forget you also have a cam, so without the cam it woudl be the usual 250-260 rwhp powerdyne.

Im really interested to see what Shirl dynos.

Nobody is running with just force induction alone. The only one that did that was James Bawkey the founder of this kit. Just read the article at this section.

I haven't done anything to my car lately. For one thing, both my 89 bird (rebuild engine and now the axle) and my truck (transmission gone) is being fixed.

There's no good track here in S. Cali. and I'm not a racer anyway. I wouldn't be a good example. But I hope to dyno later this year when I get my headers and update my fuel system.

Ironman24 Thanks for the numbers. I want to see how the ATI do in your set up. See how the number comes out without any change to other things. If you can, run the same boost number.

To make it even, run it without the intercooler and see if it gives 285. [img]graemlins/thumbsup.gif[/img] My money is on Powerdyne ;)

i went to the ATI website... Am I missing something: they don't offer a kit for our cars. do the individuals who run the ATIs do a custom installl or like order an LS1 kit and adapt it or what? i'd like to know becuase RK sport is jerking me around in my attempt to purchase the PD kit...

SO.........You started out with 220 rwhp with the cam.Then with the powerdyne you went up 64 rwhp on 6 pounds of boost and ended with 284 rwhp. Then with the 50 shot of nos you jumped up another 55 rwhp and ended up with 339 rwhp. Very nice. I just still wish you could have tried ONE TIME WITH THE 10 pound pully. You would have defiently been over 300 rwhp without nos.

Well so far your 284 is the current high that i know of for a 6 pound powerdyne on a v6 f body. But then again your numbers arent fair since you have every mod known to man. He he.

As far as powerdyne users not wanting to see the numbers with nos...COME ON?????!!!!!!!We got no intercooler man. Were already at a huge disadvantage. Everytime I dyno my car here in Hawaii it's 90 degrees outside. Everytime I race my car through the 1/4 mile it's 75-85 degrees out side. Im sure that I gotta be loosing a minimum of 10 rwhp just due to heat.

So if some powerdyners found a GREAT way to kool down the intake charge....Im Happy. Plus for track purposes its all about the 1/4 times. Whatever combo you use to get there ....RUN WHAT YA BRUNG.

Now if he had posted his dyno and been running like a hundred shot and only pulled a 339 when combined with the powerdyne I would not care about his numbers. Theres afew people on this board running close to his numbers with just a 100-150 shot of nos who are also in the 12's.

But who is running 12's with a 50 shot???????Its the powerdyne giving him roughly 80 Hp at the crank and 64 at the wheels thats giving him the power.

I would much rather see some one dyno with just 10 pounds of boost instead of the 6 psi/ 50 shot combo... But trufully without an intercooler or alcohal injection or atleast a 25 shot of nos to kool things down the numbers from the non intercooled 10 psi wouldnt be to much better than the 6 pound numbers. Maybe another 20-30 to the wheels if were lucky.But defiently not another 40-50 rwhp like a intercooled system would see running 4 more pounds of boost.

Im very proud of the 284 he pulled. Thats close to LS1 rwhp. His car was put together very nicely. I will probaly get with him about that cam. Seemed to work pretty good.

Stephan I know you are all about the numbers. Im kinda the same way. I am trying VERY HARD to get you some 10 psi powerdyne numbers. Im getting 10 psi no problem and Ive got an intercooler kit being delivered to my house right now. All I gotta do is get my computer worked out so my third gear can go past 95 mph and 4800 rpm's from a 3.08-3.42 gear change I did.

I am the perfect subject for this because all I pretty much have is a 2 1/2 inch exhaust,160 thermo and thats about it. My cars very close to stock besides all the induction stuff that goes straight into the powerdyne anyway.

Well theres my opinion on him dynoing with the 50 shot of nos. Laterz

There is a dyno day here on March 6th... And I think the kids are going to be gone to their great-grandparents on Friday night for a week, so I should be able to get away.

My goal is to get my mini-afc on this weekend, do some tuning over the next couple of weeks, and dyno on the 6th with the 10 psi (no intercooling and no nitrous).

What is a mini afc. AFTERCOOLER?????

I wish... [img]smile.gif[/img]

No it's similar to a maft. ZZPerformance sells it. It goes inline between the maf sensor and the pcm. I need it to account for running an LS1 maf sensor, because the LS1 sensor output is on a much different curve. Without the mini-afc my car runs way too rich at idle and too lean in the middle and up top. The mini-afc 2.0 lets you adjust the sensor output at 13 different points, vs. only 1 or 2 points with the maft.

The only way I'm driving the car right now is with the maf sensor unplugged and the pcm going into a default mode ("speed density") to control the injectors. So I'm hardly driving it all for now....

any updates?

Yeah I posted in some other thread though....

I was still running lean, but dyno'd anyway, to see where I was at.

I got 230rwhp, compared to 160, so a 70rwhp gain. But... that was running 16:1 and 17:1 a/f ratio on top end!! So that was costing me some serious hp.

That was one week ago. The middle of last week I put the fmu on, and got the a/f under control, for the most part.

Took it to the track this past weekend, and got a 14.10 at 99.8mph, vs. a 15.43 before the blower. About the same temps, and the same 18" street tires. Dropped 1.33 seconds.

The mini-afc didn't do it for me... I just unhooked the maf sensor and let the pcm run in speed density mode.

Would there be any interest from the supercharger guys if we could build an intercooler system for your kits?

[AllTheGoodNamesAreGone]

if its for the powerdyne I may be down.. all depends on price/effectiveness.. otherwise i will just make my own..

[BadAzzRS]

Id like to see one of you guys with 4.10 gears, a cam, slicks, and a blower. i bet your 1/8 mile time would be something interesting. [img]smile.gif[/img]
