Wow, 3 pages already, huh? Sick.
Whats up Sean?
Whats up Guys, Im Max. The owner of the Prelude. I see I have alot of questions here...
Some I can answer right off the top of my head - like, someone asked if I was running a stand alone. Yes. I am using an AEM EMS stand alone unit.
Car is down right now, getting the head worked on. Right now it flows almost 360CFM, which is alot for a honda head!!!! Im using oversized valves, and its a nightmare because of the camshaft's lift. The exhaust Cam is -3*, and the intake is +5*, and the valve overlap in VTEC is .040", and givin room for heat expansion, id' say its closer to .030" overlap. Close? yes. Major VTEC? yes.
Not running Methanol, Im running a Straight Alcohol Blend into the intake manifold with two 1,600CC injectors, but I plan on going with 4 500CC injectors, placed right under the 440CC RC's that im running for gas. Im familiar with tuning, but not with this stuff, a friend of mine is doing it - and Im not sure hom many questions I can answer about this subject, without finding out information first. I think its around 70 - 90% alcohol when WOT over 7,500RPM...I know that it fucks up my Wideband (AEM UGEO), and it says my A/F is 4.0 hahaha.
Generally I am running around with 91 in the tank, some times I may blend it with some 118, but that shits getting to expensive...If I know im going to go race around, I'll put straight 118 in it, and go VTEC around
VTEC crossover is at 7,000 RPM, and carries well to 10,200 RPM. Even though I know the motor can do it, I play it safe and stop it at about 9,200 RPM. The torque steer is actually pretty bad. I dont remember talking about this sean! haha. Well, its not terrible...but its annoying. It even worse because im using an Un-sprung clutch, and its hard to get off the line quietly. hahahaha.
Here are Dyno numbers. I know they arent "sheets" but alot of people can vouch for me (maybe not here..but ya).
91 oct. straight - 268whp / 200ftlbs
91 oct + Alcohol - 340whp / 243ftlbs
118 oct. straight - 321whp / 221ftlbs
118 oct + Alcohol - 369whp / 276ftlbs
Those are my standing numbers right now, without the ZEX 175 shot of nitrous that I am adding on as well.
So im guessing with the ZEX kit, on 118+A will be somewhere around 540WHP / 350FTLBS.
Its rude. its crude. its impractical. its a pain in my ass to drive. But its alot of fun...but the thing that sucks is FWD. I miss my 04 Cobra for that reason only.
Thats all I can think of for now. Any questions/comments are appreciated, good or bad.. Everyone has thier own opinions!
