Finally, Divorce is settled so I decided to celebrate with a visit to the DYNO.
The LXI-FLYBY 429whp 88 Honda Accord A20 Turbo Dyno (http://www.youtube.com/watch?v=gkpj3LkdhMo#)
A20-T/SC6152S powa!
429whp and 361wtq at 26psi boost!
It made 325whp @16psi boost, 282whp at 14psi. I think the SC6152S is a little on the small side for this motor and choking it up on the turbine side because we were spooled and fully boosted quick but the peak numbers seemed to be at 6500 then the power stayed flat after that, plus we made good numbers in lower boost levels but gains sort of leveled off after 400whp... I feel there is more power to be had even at the same boost level (running out of spark badly, its running an obd1 accord internal coil distributor with the plugs gapped at .020 :/ ) but with a bigger turbo/bigger injectors, ( 880s are almost 90% duty cycle) I cant imagine that 500whp would ever be an issue.

Congrats on the dyno numbers, love seeing old A20s boosted. :noel:

Nice. No build thread?
-
Excellent. Never wash it.

Amazing what you can do when a vagina isn't sucking the lifeblood out of you.

Unwashed=street cred haha. Meh thats what happens when you have the car on a tow dolly in the snow. Filth.
Amazing what you can do when a vagina isn't sucking the lifeblood out of you.
truth. That is a very long and fubar'd up story.
But yes, ill have to get a build thread going...
-
nice to see ur still around. not too many of us left
-
Thinking about upgrading to a precision 6262 or 6265 vs the SC6152S I have now. Looking for more exhaust flow primarily... opinions?
-
FUCK YEAH!
-
fuckin love this car every time I see it.
-
very good sir! awesome ##
-
specs?
What dist are you running?
-
Thats a fucking badass sleeper.

"You put up with it" is not long, but it is fucked up.
It made 325whp @16psi boost, 282whp at 14psi. I think the SC6152S is a little on the small side for this motor and choking it up on the turbine side because we were spooled and fully boosted quick but the peak numbers seemed to be at 6500 then the power stayed flat after that
If it did that at lower boost then it comes down to a flow issue; eyeball fuck the manifolding and consider a cam, or a cam gear to retard the existing one. A turbo only makes power and then holds it flat when the compressor is maxed out.
running out of spark badly, its running an obd1 accord internal coil distributor with the plugs gapped at .020 :/
Plug gap is irrelevant. If the car wants 0.015" gap then you give it 0.015" gap. It means nothing.
You're dealing with 3000 year old rotted wiring. Upgrade the power to the coil with fresh 10 gauge switched across a new 30A relay. The Mustang boys do this with the classic 5.0 cars and get 600+ from a stock coil.
All that said, solid fucking work. 400+ from one of the finest sleeper chassis ever made = awesome. I liked it so much I two starred your video (lacks nudity, sorry).

Ill take that as a compliment JD O0 Anyway, Its got a ported head, AEBS intake mani and ITR TB, SI industries Valves/Springs/retainers with an old Gude Bullfrog 252 cam (yes, a medium NA grind)... Im running a stock 90 accord obd1 internal coil distributor off a chipped p06...

Any transmissions issues,kick ass stuff man
-
thats fucking awesome, good power too!!

<3
I didnast click the thread you linked to because I'm on my phone and it's alhassle, and necause zsteven Paz sent me some authenic Columbian FUUcl you liquor. IDK what your turbo manifold is like, but a BiG plenum Vickie-X or a ca. (Plus adjustents on the dyno) will shoot you right.

I thought the 6152S was good for a hair over 600?

Hoo-aaa!

Heres what the compressor map looks like right now at approx 500 crank hp at 26 psi boost:what the engine makes now. Going to 600hp results in the chart going off the map... im guessing around 525whp but its showing 35psi boost. Either way adding more boost im starting to hit a wall but i can tell compressor efficiency is starting to roll off and this turbo has a small turbine I belieive its equivalent to a .63 stage 3 wheel which isnt very big.

Right now the motor seems to peak out at 6500 rpm but my thought is that with more turbine flow Itll free up some power at the same boost level and maybe even make more power at a later rpm, because the power seems to flatten out after 6500.

Around 630 max according to what I was able to dig up. From my understanding it used the GT35R wheel, but the other differences make the map for the GT35 not applicable.

This is a GT35R

This is a SC6152S like the one I have (on left). I cant see a difference in the housings, and they use the same wheel, so what differences are you referring to? This is not an SC6152E which uses a different housing
-
Just going off of memory, the fact that precision says it is good for 630 and the map for the 35R does not.
Several DSM guys have touched 600 with it also.
-
That is true but but the 6176 is is rated to 680hp same as the 35R, the difference is in the turbine. The main difference between the SC6152S/SC6176S and GT35R is it that the 35R is ball bearing and they all have different turbines. the 6152 has the smallest by far and I believe thats whats limiting the motor... The SC6176 has a p trim turbine (76mm) which I think would free up some hp vs the 69mm turbine in my 6152S...
Edit: Also im using an (8" JRC intercooler its either 2.75 or 3" thick) but im not sure if it has become a restriction yet...
-
Crank vs wheel numbers. Corrected vs uncorrected numbers.
-
good numbers regardless
what gears does it hook?
-
havent had much street time to see if itll hook, its cold in ny. The dyno numbers were with the sae correction on, uncorrected the car made a good bit more power

WNY Area... specifically southowns area...

Damn your not that far (I think) North Nj.

What up Brian! Yeah man it has... too long. I heard your car was making 750whp now? Do you have it still together etc? I always a big fan of that car. Sleeper=WIN!

His Accord has been in article in Honda Tuning and last fall in a book about Sleepers. :noel:

Update:
Had a problem with the car... Engine has maybe 100 miles on it, and the headgasket is blown pretty bad. Im actually surprised that it didnt blow on the dyno... The oil is chocolate milk now, but never looked very clean in this engine. The engine never overheated and ran okay... It looks to me like the head is warped though, so it must have been like that since installation. The engine has head studs on a stock composite gasket and the block is decked... The engine still has 70+ psi oil pressure hot so im betting the bottom end is still ok, but the cam looks marginal. Im gonna have to have my machinist take a look at it. Fuck this shit sucks
edit:
Thats probably why i could only get 429whp at 26psi boost, I felt it should have been 500+whp. At least I feel a little better knowing that the headgasket must have been messed up before we even showed up on the dyno.
-
ya car came on boost very fast at dyno after some tuning issues were fixed. that being said turbo def is limiting it from what I can tell. you could hear some pretty bad compressor surge on the top end before lifting off. I still say screw it jay toss a freaking hx35w on that beast and come to the dark side

Were both of you nogs at the PNW meet?
Dustin I wish had those name tags, I do not know how many nogs I met and did not know it. :-\

Thats the part that sucks about a meet. At last years NE meet, once most the rhmt'ers put them on, it was like meeting family that you never met :noel:

I wish. Me and shanerv and a few others are in NY. It would have been awesome to come to the PNW Dyno though
