love the whine of a SC but i will say this i do ALOT of dyno tuning and if you make 3 back to back pulls on a JRSC car you can expect to lose 10hp all the way up the graph every pass...... let it kool for 10 min.. power is right back up there. havent tried one with h20 injection yet i gather that this would help ALOT
Man you guys just motivated me to put my s/c back on ,I took it off to sell it for b swap.But I,m glad others are using this setup.[IMG][/IMG]

hey all you ef supercharge guys out there, do you have clearence probs with strut bars, i have the password 3 point and looks like it might come really close to the throttle body, anyone know if there are clearence probs with these setups?
thanks
thanks

looked like it was ok but you never know, im finding that out after installing my dc 4-1 headers
boo</TD></TR></TABLE>
told you to get the kamikaze anyway.
i never had a problem with the 4-1 header on any of my old EF hatches.
i even had a B16 with one. it sat close, but never touched.
maybe because you bought one for an EK. who knows?

they do on higher boost levels. that graph is most likely on stock pulley.
then again, look at your graph, and see where your peak tq is...... probably redline.
on the blower, at 3500 rpms, its probably got more TQ than your engine at redline
tuning is really needed to make good numbers on these. cant just slap one on and go.
if i ever get around to it, i'll get mine tuned on 11psi. (hopefully soon)

On the third run with some fiddling (timing) we made 113 @ 4500 plus I had the stock exhaust holding back a ft/lb or two. This was also on the stock computer

what do you have done? that ***** a super d16a6!
</TD></TR></TABLE>
This motor died last summer R.I.P. when a valve smacked a piston out of the blue.
D16A6 Block
D16A6 Head --> Head was rebuilt with all new stock parts by a local head place in CFL. A smidge milled for flatness and the ports cleaned up. Not even enough to qualify as a P&P but just enough to make it nice and pretty like it came from the factory. Stock Cam and cam gear.
D16Y8 DC Sports 4-1 Header
D16Y8 Intake Manifold --> Qualifies as a bolt on....well so do turbo's but you have the idea.
B18A1 T/B --> IM Port matched to 58mm
Ebay Intake
Distributor King Dizzy
PM6 ECU
Stock LX Sedan Exhaust
So maybe it wasn't a stock D16A6 because of the I/M + T/B combo but it sure was fun. This dyno was also done in 102F Heat

Considering I made like 75wtq stock I'd say it did a pretty good job for 6psi.
You've got it a bit wrong too, it's up'ing the torque DOWN LOW, it's the press and go feeling.

Well the easiest way of hitting 200whp with a SC SOCH is bumping up the compression. A friend of mine made 207whp on a D16Z6 with arias 11.5:1 pistons and ditched the FMU for RC 550's and Hondata S200...the car had all the other basic bolt-ons he had a greddy 4-2-1 header, Full 2.5in exhaust with Carsound cat, Straight piping all the way to his magnaflow oval muffler, AEM CAI, ZEX cam...
Alot of other people that i've talked to have said the bumping up the CR anywhere from a 10.5:1 to a 11.5:1 is a CR that superchargers love to play with...

What octane fuel was his dyno/tuning done with? I also assume that wasn't with the stock pulley. More details please.
I'm running A6 pistons in my D16Z6 which nets around 10.5:1. I ran that with stock 6 lbs. pulley with out any problems. However, I doubt I could've gotten away with anything much higher on California 91 octane pump gas.
I wanted to play with water injection but, never got around to it. I think that would allow for higher compression on 91 octane with a decent safety margin.
BUMP....

Hey was running 91 Octane on a 9lbs pulley....it was tuned a bit on the rich side AFR 12.5 - 13.1...they ran it a rich to advance the degrees on the cam to get the most out of it....I can't remember much of the details on his set up since the car was sold about 5 months ago...
I have another friend thats doing a similar setup but on a D16Y8 engine but he's using an SMSP header, ITR 3in Short Ram Intake,ITR TB,2.5 Straight through exhaust, Crower Stage 2 Cam, 9lbs pulley, Ported& Polish head w/ 3 angle valve job, Arias 11.5:1 pistons, Crower Rods, Similar fuel setup with alcohol injection, tuned on Crome Pro...I was talking to him and he said that set up will get him close to 210 -220whp since he can run alot more timing with the alcohol injection...
