My SOHC-T 297 whp Dyno
 

Got her up on the dyno and am failry pleased with it. This was not a dyno session but rather a dyno day. Meaning, pull it up and see what it does. It definatly needs some tuning as up top it was pig rich at 10:1 a/f. Then again, I never tuned that portion of boost that high :P

Made 297.6hp 236tq at 20psi. Click the thubmnail for a lrger view. I will try to get a scan for a better pic.

nice. stock block? whats the setup? ;)

Re: My SOHC-T 297 whp Dyno
 

Thanks. Setup is in the sig. Stock sleeves, stock block aside from block posts.

Re: My SOHC-T 297 whp Dyno
 

can't read a sig can ya?

Re: My SOHC-T 297 whp Dyno
 

why a d15 head?

Re: My SOHC-T 297 whp Dyno
 

Cause I had a D15B and bought a z6 block and crank for 50 bucks :)

Re: My SOHC-T 297 whp Dyno
 

No too shabby for the Stock block. I would of bump herup .5 to 1 more PSI just to break 300!!

Running Pig Rich on 450cc's? Nice to know you can go up yet with the boost without getting bigger injectors!

Re: My SOHC-T 297 whp Dyno
 

yea, what was the duty cycle @ 20 psi? 1000%? O0

Re: My SOHC-T 297 whp Dyno
 

wow, those are some good #'s, how's traction with that quaife?

Re: My SOHC-T 297 whp Dyno
 

Actualy I had some room. They were past the "safe" limit at 89% but the a/f went from 10:1 then of the chart. The wideband only read down to 10 so it was unsafe running too much fuel. That is why I didnt want to up the boost even more. Next time will be a tuning session and it will see 300 or bust.

Re: My SOHC-T 297 whp Dyno
 

i didnt see the rods and pistons listed in the sig :P

Re: My SOHC-T 297 whp Dyno
 

Hot diggidy, I bet that makes for a fun street car. 8)

Re: My SOHC-T 297 whp Dyno
 

Good #'s.

Not exactly a stock block if it has pistons and rods.

Re: My SOHC-T 297 whp Dyno
 

no its still a stock block, with other than stock internals. I think he means its not sleeved.

seriously, i dont have an aftermarket pump or regulator, but im maxing ---- out on my supra 440's (and it still goes lean at 18psi and up)

Re: My SOHC-T 297 whp Dyno
 

Look at the size of your turbo :P 60/63 vs my 48/60. I could see how it leans out it flows a shitload more.

Re: My SOHC-T 297 whp Dyno
 

you do realize the jdm d15b head is the same as a d16z6 head with a different cam, right?

Re: My SOHC-T 297 whp Dyno
 

Exactly why I picked up my Percision 680cc's when I had some paypal money sitting around.

Re: My SOHC-T 297 whp Dyno
 

FYI The dyno dynamics dynos read low compared to a dynojet. So...for compensation theres a 10% difference wich would put me well over 300 (around 327whp) in comparison. As for the cam in a D15B head thats still debatable. Although the keyway is different that is for sure, theres still no 100% proof of the lobe lift and duration. I run a Y8 cam gear to get correct mechanical timing if anyone was curious due to the deck height difference bwteen a Z6 block and a D15B block. I still need a shitload of tuning as right at VTEC it would go a little lean in the 13's and richen right up. My a/f was all over the place and tonight I will post it up for you non-believers. The graph clearly shows 21psi spike (long ass vacuum lines to my boost controller) and holds at 20psi. The a/f right around 4600rpm dips in the 13's (rises on a graph) then goes way the hell fat at 10.5:1 and drops more through the powerband and even off the chart into the 9's. There is definatly HP left on the table but I feared cylinder wash with it that rich. I think with some tuning I should be able to squeaze a few more ponies out the 450's. I would like to shoot for 330 to the wheels on the dynamics (read that as 360ish dynojet) but we will see. Sure thats a lot of boost on stock sleeves but its the HP you need to look at not so much the pressure it took to make it. Imagine if I had some headwork, larger exhaust or even open dp and I tossed in my 660cc's heh...nah dont need it. I'm happy with it. I look at it like this, between the turbo setup and engine work I am well under $3k. 300hp is darn good when you consider what it cost for a B swap, turbo and 300whp.

Re: My SOHC-T 297 whp Dyno
 

thumbs up...what comp ratio are you running?

Re: My SOHC-T 297 whp Dyno
 

you just said duty

Re: My SOHC-T 297 whp Dyno
 

Wow, thats a nice setup! hopefully i might be able to push around that with my stock setup.

Re: My SOHC-T 297 whp Dyno
 

how the ---- did you make over 300hp on a .48/.60??? i need an ostrich

no, obviously i did not

Re: My SOHC-T 297 whp Dyno
 

nice setup/ nice numbers out of a stock block 1.6... about the dyno jet/ dynamics, couldn't it throw that number into the 260's too? just wondering. hope its higher so that you might have a chance with me. haha keep us posted on any more info. :y

Re: My SOHC-T 297 whp Dyno
 

damn im jealous....very nice. how is the quaife with 300 hp? do you see any improvement?

Re: My SOHC-T 297 whp Dyno
 

not too shabby.....
