Met a guy with a cool custom Prelude

[SeanPlunk]

Today one of my friends brought over a buddy of his who has been building up his custom Prelude. He wanted to do something different and not do forced induction. His goal was a normally aspirated 4 cyl with 400+hp. The work is impressive: custom paint, a totally beautiful fabricated header, built motor, etc. The car revs to over 10k rpms. Here are some pics and a list of mods (http://www.precisionautocustoms.com/homepage.htm):

I think Max will get on here eventually and he can tell you more about it then.

wow freakin impressive a 2.6L honda motor dang. its kinda cool i wanna hear this thing in person. the only thing i dont agree with is his N/A is best sticker lol but a freakin clean car none the less

[Vettezuki]

VERY impressive. My only question is weren't these FWD? Torque Steer? Even though, awesome skills.

I thought so too. I think the whole thing is kind of cool and tastefully done. He is currently getting some head work done, but should have it back up and running soon. I'll make sure we get a video :)

They are FWD, but he indicated the torque steer wasn't so bad. I'll ask him more about it later or hopefully he'll sign up and enlighten us :bigthumbsup:

lsd and better tires usually make tq steer managable. my 04 evo turned to front wheel drive when the transfercase when out and the turbo kickin in so fast is what made it violent same with the srt-4 on an N/A car with a smoother powerband it should be more managable

[BADDASSC6]

13.5 compression:nuts: What fuel is he running? Serious build. Any dyno sheets or runs made. 400hp is alot for 2.6 even with revving to 10k and 13.5 compression.

He is running 91 octane + methanol. I think the 400hp is flywheel, not rwhp.

[BADDASSC6]

Wow! That's insane. I guess the methonal would definately get hte job done, but does that means he has to run it all the time or only whenit's on a heavy load?

Not sure. I think he said something about a 5 gallon tank for meth, so I'm thinking maybe all the time.

DAMN IT ALL TO HELL, I DO THAT ALL THE TIME. Stupid FWD :rolling:

:huh:

[st-evo-9*corn fed-8urvet*]

hmmm the how much meth is ran and how it kicks in question is actually a really good one im interested in the answer!

unless he has a stand alone ems then i doubt he is running it full time.

also if it where running full time then the 5 gal would go out on him quick.

the only thing i could think of is its activated when his vtec kicks in *no this isnt a honda joke* that would make the most sense, being as how vtec raises not only timing but compression and just like boost when the hightend compression kicks in thats when he would need a higher octane fuel to not detonate. thats my theory on how he's running his.

but i wanna here it from the horses mouth and see how close i got. :bigthumbsup:

He was talking about the VTEC and tuning, I wouldn't be at all surprised if you're right. If nothing else I think the engine bay and headers are kind of a work of art :bigthumbsup:

As I recall from bgn8711s Turbo Buick, the alcohol pump gets it's signal from the MAF, so it's continuously variable. Then you have a manual "trim" to turn it up or down, so nothing under low boost, bunches with heavy boost. In short pump controlled by MAF signal. Have no idea here. :huh:

LOL, I agree, forced induction FTW :judge:

I do admire him for doing something different though and for doing it tastefully.

hmmm maf signal controlled meth interesting ive never heard of that. all the kits i hear of at least for imports are boost controlled and pretty much throw more meth the more boost signal its reading.

but then again there is something about gm mafs that make them easy to hack into...most imports actually swap out to a gm vette 3" maf becasue of its bigger size duhhh but with a simple signal translater kit thats pretty much plug and play kinda cool shit.

i do need to check out this turbo buick i think if i ever had a domestic id want to put that engine in it lol.....imma sucker for turbo's :-(

Technically, you're more of a "blower" for turbos.

[kameleongt]

car looks great cant wait to see this at the next motorgen meet if he makes it down :)

lol hey suckerin or blowin it all fun till someone pokes an eye out :huh:

[MeNmyType-SH]

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 :sm_laughing:

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. :thumbs_up:

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! :)

Welcome to the board dude. We may not have talked about torque steer, it could have been my imagination, LOL.

When do you expect to have this thing running again? I'd love to see it at our dyno day in February...

[MeNmyType-SH]

For sure dude, thanks for the warm welcome!!

I think I can probably make it down there...but I may not be able to go on the Dyno...we'll see. I have brand new rings on the pistons, as well as bearings and some other odds n' ends, and I gotta break it in. I should be cool to go by then. I might have my alcohol setup off though, I take it off whenever im breaking in a motor.

Even if i come down with just 118oct, I'd be happy to lay down some mid 300's on the dyno for fun. :)

Here's an alternative to using the MAF signal

Joe, are you using any alcohol with your CS?

[joedls]

Joe, are you using any alcohol with your CS?

No, but I had a snow performance boost referenced kit on my 68 when I increased the boost to 12 lbs. Unfortunately I fried a piston first. So I replaced the piston, installed the water/methanol and life was good again.

[MeNmyType-SH]

Hey, Sean said something interesting. He said something about the hours that went into the engine bay..I don't have it infront of me, but I can take a CLOSE guess and say that there is probably about 750-1000 HOURS in that. About 10 hours, 25 days a month, for 4 months...

Welding, Grinding, Primer, Sanding, Grinding, Primer, Sand, Weld....a lil' bit of filler...sand, prep, primer, paint.

It was a nightmare. Could have taken the easy way out and bondo'd everything, but we did it the right way! Welded all the holes shut.

I have to say, Honda metal is HORRIBLE to try and weld with. its really crappy quality.

Just another day at the shop. :)

That is an INSANE amount of hours, LOL. It does show though, the engine bay is a work of art. I fixed your user title for you by the way :rolling:

I noticed when I posted the last one.

Sick.

And ya, I can tell you more than afew days, where it seemed like it was never going to happen..

[BADDASSC6]

So what was your goal when you decded to build this car? Show? Cool daily driver? from the pictures the craftmanship looks great, I was just wondering why a predlude. I've thought aboutputting together a Honda hatch for road racing because the runing cos of there series is so much less.

wow dude u put in some time and love into this car and it shows. im usually not a honda fan but wow i would so drive the shit out that lude everywhere i went lol. good job man. so whats your end all goal with this car and on what type of set up do you plan on stopping at?

[MeNmyType-SH]

Well, as soon as I get my head back, it'll be going on the cover of Honda-Tuning Magazine...

Then I plan on showing it somemore, maybe afew races....then selling it...

Think of a new body M5, or i might get another 03/04 Cobra.

the new m5 body would be cool. it seems like price isnt really the biggest issue with you on things so beefing up an m5 would be amazing to see done. or if you can afford an m5 then maybe you could consider the audi R8 sense its in a similar price range and a sexy car. either way u seem to do good work so im down to see whats next from you
