TurboProbe Dyno Numbers???

[turboprobe]

I put my car on the dyno at NCR Performance, Matt Maas's shop, and we decided to do a little tuning and testing. Turns out that I am fairly rich, which is good, and running a 12:1 a/f ratio across the whole power band. So, I guess your wondering what kind of numbers I put down.

On The Dyno

270 WHP

Keep in mind, this is to the wheels, and I'm only running like 7psi. So, with a little more tweaking, and a little more boost, 300 whp is not far away.

12.1 is probably right where you'd want to be at. Nice #'s, it's always cool to see quick sport compact that is not a honda. Now get some tires and take it to the track!

nice #s

X2 im glad its something different

Real nice numbers and the tune looks spot on! It's going to take 9.5 psi to make 301whp according to the efficiency equation. Since you are running such a large compressor, it's actually more efficient running more boost, so you probably will be making more power per psi than the equation makes. Just so you know making horsepower per psi should be a linear equation off of a base run, but (in your case) where a turbo hasn't even gotten to it's main efficiency islands yet, it generally does beat the equation, assuming you run into no problems (flow limits on other parts).

I'm not trying to start a shouting match here but by the results posted it looks like a few might have come close to putting their entire 'foot inside mouth'. I must admit, I was skeptical also but I've learned to hold back comments unless knowing exactly how the outcome is going to be. Those are GREAT numbers (and not to take away from yours) but I've seen turbo'd probes make a lot more power, so I know it's possible. But like always it's all about the setup and most times that is the #1 secret to making power.......

Congrats turboprobe, hope to see you around!!!

yeah, i know that i can make more hp. my friend matt has 486hp to the wheels in his turbo probe. but he also has stand alone fuel managment, among other things. as far as hitting the mark, i was planning on getting a manual boost controller, and running 10psi. that way id hit 300, and then could turn it up or down as needed. and yes, the piping i have isnt the greatest, but itll do for now. when i decide to upgrade, the turbo will reside in the a/c compressor spot, which is on the front left side of the motor, which means less piping, which means more power. so we see if i ever get that far. all i want is 300 hp, and a decent track time. just to prove to myself that i could do it. and also like others say, to do something different. but thanks for the compliments guys.

I am wondering what would happen if you tried to run a higher boost at the lower RPMs. The reason I am wondering is because the heat loss due to conduction of heat with the cylinder wall and head will be greater at the lower RPMs becasue of the longer period of time for the air to cool, which will keep the air and fuel farther from higher temperatures and avoid detonation. Also, the lower rpm will give the injector more time to fire fuel into the cylinder. In the end, you could have a flatter hp curve.

If you do not want to try this at max boost, try to add more boost relative to a lower setting for normal peak boost. If you are running 5 psi, try to run 6 psi at an rpm before your peak hp. To be sure that everything is in working order, pay close attention to the exhaust gas temperature and compare it to other areas of the SAME HP, not boost or torque.

CJ you are pretty right!!! hehe!!!!

so 9psi did about 300whp??? if so that is pretty low considering it's 6cyls. Alot of the 4 bangers I do get high 200whp at 9-10psi. Either way 300whp is 300whp at whatever boost level it's still nice to have that power. The setup with 2700lb should run mid 12sec. The reason why you wouldn't would be traction... I've seen Probes have tons of trouble hooking up. don't know why, but they just don't hook so good even with slicks. maybe a coincidence!!! good luck at the track bro.....

Don't you think the RPM at which peak HP occurred, is an incredibly relevant detail not being mentioned here?

Judging by the Probe's dyno, he made peak HP at 6200 RPM. I'd say it's very likely the 4 bangers you built made peak HP significantly higher than that.. How about comparing the torque to torque? Just having some technical debate with ya

you are correct there syclone no doubt. The probe will make 300whp at a lower rpm and more torque. The reason why a honda/acura same weight as probe(2600-2700lb) 4cyl with the same 300whp w/ less torque would run close or even better then the probe would yield to no other then the gear ratio. Most of the cars I do depending on the car weight and size slicks I can gear them differently for best results!!! Most Vtec hondas/acuras come with very close ratio gears therefore even if the smaller 4cyls need to spin up the rpms to make power....it's still fine since it's gearing keeps the BIG power on tap in the next gear........ That's the reason why 4cyl fwd turbo are so deadly at a downshift @ high rpms!!! Most guys in here know that don't lie!!! hehe!!!

Hence, in my wife's blk civic h.b. turbo with 6psi ls/vtec I was already beating 95% of whoever I downshift-raced.........and don't go flaming people I don't race cavalier's w/ type R sticker, camaro V6s, ghettoed-out hondas, DSM stock boosted turbos etc...... I did race a syclone(maybe it was you 11.7-12.0s) and hung pretty good to about 100mph or so!!!

[Bee]

who's the guy with a V6 Probe that ran 11.0@130ish????

Now that was one fast Probe.... haven't seen him in a LOOONG time...
Last I saw it was on boost and NOS... VEry big slicks too!!!
One of the cars that truely impressed me!!! He was out at IMPORT wars for like 4-5times and couldn't get the car to run good... Then one event he came out and busted almost 10sec!!!! bow doooown!!!!

I think most of the time, fast cars are down so long since it takes big time money to keep them up-to-par!!!!

[junk mx6 no rly]

dont mean to jack your post but is your probe the silverish grey looking one?ive also got a turbo probe well from the factory im working on getting a t3/t4 on it.

But is this a comparison of a 2.5l 6 cyl to a 1.6l 4 cyl


200 = 300
1.6 2.5

the displacement is a big player here.

Alot of the 4 bangers I do get high 200whp at 9-10psi.

Mine gets around 244 @10psi, and 271 @12psi and it's only a 1.3 liter.

It takes a bigger turbo and more boost to fill larger cylinders. Therefore, you'll gain a lot more power in small engine applications, because your pressure is that much greater in a small area.
My bike @ 33psi puts down over 550+rwhp, and @ 36psi would push nearly 600. With stock bore, stock stroke, stock cams, and a stock head, that's pretty impressive. Add turbo grind cams, a little head clean-up, and I'd see hp numbers well into the 620 range...

[Syclone0044]

Do you have a dyno sheet of your bike's 550rwhp run? What peak HP RPM and what was the torque? How fast does that bike run??

[Blackhawk01]

I'll try to find a picture that I took of the dyno sheet.
Peak HP is made around 10,000rpm, and torque is a hair shy of 300#.

I can't tell you what it runs, then everybody will know...
Just kidding I run with a clocks on all the time, and race it in a series.


Best ET is an 8.50, best speed is 172.
But that will change this weekend.

[Blackhawk01]

Here you go.




is 431.8hp 235.6# @22psi
is 461.3hp 248.1# @26psi
is 514.2hp 273.9# @29psi
is 553hp 296.0# @33psi

[Blackhawk01]

Here's the machine...







Should go very, very low 8's maybe even 7's if everything goes perfect on one complete pass.

[twicks69]

My god, that is the most beautiful, scary, crazy bike--AWESOME!!!

Freakin kick ass numbers--is that the GT35R turbo kit?

Good luck at the track; I hope that you get some clean passes in!
