Just Dyno'd My Car Again

Well i just dynod my car today ok
Before Gude Head w/ cam it made 141.3 hp 143.5 torque
After Gude Head Install 157.2 hp 154.6 torque
Not too bad do u no Gude actually clain 50 hp more at the Wheels!!!!!!

Those numbers seem low. Ive seen other SOHC VTEC's dyno around 160-170 with a GReddy kit. How much boost are you running? Im not trashing your car or anything, I just want to know because I thought the turbo alone would give you more hp than what you posted.

I guess Gude made a little mistake in their estimate! :rolleyes: :D

Im running 7 psi boost!!!!!!
I dont know thats my numbers and i got a lot of parts on there???

You need to build your bottom end and turn up the boost. The reason you have lower numbers is because you have less displacement than a SOHC VTEC.

out of curiosity what kinda cam is in that head?

The cam is a high lift cam that cam from GUDE

but ramp duration and overlap would be the key

Not to be a smart@$$ or anything but doesn't his sig say that he has the 1.6SOHC VTEC D16Z6 conversion?

Thats what I was thinking, and how much less displacement could he have? (1.5 vs. 1.6) With all the upgrades and running 7psi of boost, I still thought the power output would be more.

might be the tuning....how's the fuel curve look like?

I think one of you is talking wheel hp, and the other is talking Flywheel hp.

So am I not crazy in thinking he should be pushing closer to 170hp?

And turbocivic4, again, Im not trying to slam your ride, just the opposite. I just want to help you get the full potential out of your turbo, being that I am not that technically advanced, Im hoping someone else can help you out. I just know what Ive read before on power output with the GReddy turbo, and your numbers seemed a bit low.

No I am talking about wheel hp. Maybe Im just remembering the numbers wrong?

You would have to have one extremly welll tuned D16 to get 170whp from only 6psi.
170hp at the crank is about what I would expect for a basic bolt on install. With the cam and head package, and the right tuning, then maybe 180-190. But thats still about 130whp in basic forum, and 140ish whp with the add ons.

170whp is 10psi with rods and pistons. Or about 220-230crank hp.

I think I read it wrong then because I thought I read D16 head conversion.

hmm, must've got my numbers mixed up :confused: I think Ive overloaded my brain with all the turbo D16 research! :bloated:

We built a kit for my buddy's car running 10lbs...stock d16z motor with stock fuel delivery and it did pretty good. Never got it dynoed, but it outran a cobra....had a t3/t4 .50 trim compressor with a JG manifold....spearco IC, HKS wastegate, and custom made piping and dp....a couple weeks after, we turned up the boost to 20lbs for fun and blew it. Damn that thing was fast for a stock D16z.....GOt a b20b now...turbo setup was sold in pieces

oh, forgot to say what I was gonna say....

did the guys that worked the dyno show you your fuel curve? Is it a pretty smooth and straight curve or is it jumping up and down?

I dont no the turbo makes nice boost all the wayz u can really feel some mean power in the car. u barely need to press the pedal and ur flyin stead 80 90 or what ever, it will instantly gain speed. i have actually had a b16 with boltons and my d16 feels much more strong. i was in fact talking about 157 hp at the wheels which would be bout 180 or sometin at the flywheel

Thats what i was going to say cause i know of an EX motor runing at 8 PSI of boost with no upgrade in the internals whatsoever, just a better fuel sysrem and its pushing around 190ponies to the wheels.....

hmm, Im starting to think tuning is extremely important when turbocharging a D16, maybe moreso than with a B16? I thought there was something of a discrepancy in numbers, especially when you look at all the other things turbocivic4 has already on the car. To me, it seems like you could take the turbo out of the equation and with his bolt ons alone be making some significant power. Thats why my first reaction was that something doesnt add up.

tuning is the key when it comes to any type of Induction on a motor....even Na applications apply to this
