Joined the 400hp SOHC club...on vitaras!!
 

This weekend we had a local dyno day from a local website... http://www.idahostreetracing.com i decided to roll down and see what the beast could put down, as i have never had it on the dyno with high boost. i only got 3 runs and no tuning was involved because of the time crunch...pretty much strap it down and see what it runs...i was thinking prolly 350+ but then this came up

just for reference my setup is this
stock z6 head
stock z6 intake manifold
y8 block with VITARA's and eagle rods, other wise stock
drag manifold
t3/t4 57 trim .60/.63 about 25psi
3" open downpipe
street tuned on cromePro by me O0

im extremely stoked on these numbers, i never expected it to be over 400whp...it suprised the hell out of me because im still on teh stock head and stock intake manifold...oh and the shitty drag manifold, cant believe i got 400 hp out of that too!!! and for the haters these vitaras ROCK! FJT informed me that this IS a new record for the most horespower made on these pistons...and for those that say it wont last....its been boosted and running 20+psi daily for the last 9 months allready... :S :6

awesome man!

Re: Joined the 400hp SOHC club...on vitaras!!
 

d series FTW!!!!

Re: Joined the 400hp SOHC club...on vitaras!!
 

I'm a believer.. soon as I rob that bank i"m getting a D.

Re: Joined the 400hp SOHC club...on vitaras!!
 

Wow, that really impresses the hell out of me! Great job man. I bet you were stoked when you saw the actual number.

Re: Joined the 400hp SOHC club...on vitaras!!
 

Wow. Nice numbers for stock block, and Viartas!!!!

Re: Joined the 400hp SOHC club...on vitaras!!
 

daaayyyyyym. kick ass numbers.
the D should be the Dark Side.

Re: Joined the 400hp SOHC club...on vitaras!!
 

Damn congrats man. I bet that thing is nasty. :l :6 :y

Re: Joined the 400hp SOHC club...on vitaras!!
 

That is awesome, dirty D FTW......That is just WOW, you got there before Hotrex...lol :-*

I wonder who's going to be the first hater........ ;) :8

Re: Joined the 400hp SOHC club...on vitaras!!
 

---- your piece of ---- d series. I'll shove those vitarias up your ass so far, your ---- will have a 20:1 compression ratio.





Jk :P 400hp is pretty ------- badass on vitaras. good job!

Re: Joined the 400hp SOHC club...on vitaras!!
 

lol thanks guys..i allready had the flamesuit zipped when i decided to post it here lol just waiting for BBKA to come in..he is vitara hater #1 lo

this thing is REAL nasty too...400hp is hard to handle on the street.funny you say that...i sooo thought that about hotsex when i posted it hahahaha!! :-*

i was stoked as hell when i say the 1st number...my daily driving psi is 23 and that got me 386..i was like ---- it i want 400! turned it up to 25 and got 405! the whole dyno shop went nuts!!

lol... you forgot to mention also Oscarmayer

Great numbers :8

Re: Joined the 400hp SOHC club...on vitaras!!
 

obviously you have stock sleeves, but are you running a block gaurd or filler or anything at all? stock HG or steel? what kind of c/r is it at with the vitaras and y8/z6 combo? and congrats on the power, that is ------- amazing... :6

Re: Joined the 400hp SOHC club...on vitaras!!
 

yea stock sleeves...only mods to the engine at all are arp studs, vitaras and eagle rods :S

Re: Joined the 400hp SOHC club...on vitaras!!
 

good job, congrats

Re: Joined the 400hp SOHC club...on vitaras!!
 

The only bad thing is you have about a 1,000 rpm (6-7k) powerband lol... That thing is going to drop out of boost every shift even if you rev the piss out of it. Your going to need some serious head work, intake, and cam setup. Nice job on the 400whp mark though, with a very basic setup.

p.s. vitara's are gay... :P

Re: Joined the 400hp SOHC club...on vitaras!!
 

my penis has spots on it

Re: Joined the 400hp SOHC club...on vitaras!!
 

yea but are they 400whp spots??? didnt think so lol

people keep saying that but the thing is i make 7psi by 3500, on my datalogs from cromepro at the track i NEVER drop below 18psi the entire run. i drop to 5k and rev to 7500 at the track (z6 tranny with lsd) so im only using 2500 worth of rpms at teh track anyways. the dyno run is decieving, especially cause i didnt hit full throttle util about 4500 or so...this was my 1st time ever on a dyno (i really dont need a dyno to tell me how much power i have, if it runs the numbers at the track thats all i need) so i didnt know wtf was going on lol

and pat its ok im just flipping you ----...you were after all, my inspiration to build a d :6

Re: Joined the 400hp SOHC club...on vitaras!!
 

Yeah it's cool man, still probably a lot of fun to drive and I bet when boost kicks in it feels really nice. With some headwork that thing will rip, a gt30r would be nice too and spool way faster. Get some good times in and let us know, should be 11's no problem on slicks. Look into ZC 3,4,5 gears for your tranny if you want to make shifting shorter (freeway will suck though lol).

I got my car back to being my daily driver finally, still feels slow as piss. :( I need a built 2.0L b-series turbo setup now!

Re: Joined the 400hp SOHC club...on vitaras!!
 

Badass man we are going for 350 on a stock head and intake d15b with pretty much the exabt same setup but with nippon racing ebay pistons on 20 pounds. We got 278 out of 14 tuned on neptune by jason herrara, so hopefully ill join the club with you

Re: Joined the 400hp SOHC club...on vitaras!!
 

haha stay with teh d man!! your the og when it comes to the single slam, trust me 400hp can be had cheap and easy!!

btw i have allready run 11's with it O0
11.98 @ 118 (track was real hot that day too...150+ track temps 145+ intake temps and a corrected alltitude of 7500ft above sea level :S ) on 22x8x15's that was with a bad boost leak that ive been tracking FOREVER. i finnaly found it the day before the dyno, it was a couple pin holes in my charge pipes weld....fixed it (along wiht a leaky coupler) and this car has never run so good before....3rd and 4th gear are white nuckle thats for damn sure!

im confident this car will go at least 11.3's at 123+ i just bought bigger slicks 23x8.5x15's and i cant wait to get back to teh track

Re: Joined the 400hp SOHC club...on vitaras!!
 

well i made 193whp on 8psi. i say bring it 8)

Re: Joined the 400hp SOHC club...on vitaras!!
 

Believe me I really wanted to stay d-series, but for the goals I have going with a b-series will be easier and cheaper. The problem with going d-series is the head will need serious money invested into it, plus getting a big turbo to spool fast and have a good powerband won't be as easy, I also didn't want to deal with head lifting issues, the power on pump gas won't be as much on the d-series either.

Re: Joined the 400hp SOHC club...on vitaras!!
 

hey your HMT setup did a hell of a job! i cant believe that you lost hp by uncorking your exhaust..that had me mystified :S

Re: Joined the 400hp SOHC club...on vitaras!!
 

Dynojet is a non-loading dyno. Boost is load dependent.

Re: Joined the 400hp SOHC club...on vitaras!!
 

i run 20 psi on 93 pump with no signs of detonation. even in this summer heat! i agree the head needs some work but you dont feel it on the street...its not as pronounced as say an ls motor, where power just dies off....and i havent had a single issue with headlifting...maybe i have a freak motor or soemthing cause i dont experience any of the issues that other d-series owners do....maybe its my attention to details or my tuning...not sure. :S

what does that mean? im a dyno n00b.

Re: Joined the 400hp SOHC club...on vitaras!!
 

Damn.

I bought some Vitaras about three years ago when FJT first started selling them, then sold them a year and a half ago...

I should have waited until after your dyno plot and sold them for $300. lol

Nice numbers. I didn't think it was possible on vitaras.

Re: Joined the 400hp SOHC club...on vitaras!!
 

Job well done. congrats.

Re: Joined the 400hp SOHC club...on vitaras!!
 

How long do you guys think this setup will last without a blockguard or filler? I aint knocking the setup, I love it and wow, congrats on the 400HP, the reason I ask is I plan around 300HP on my B16 with the only mods being ARP head studs, nippon racing pistons (similar to vitara material) and Thicker cometic head gasket, I want to break in to 12's but also want to have a reliable daily driver.

Re: Joined the 400hp SOHC club...on vitaras!!
 

It should last a long time if it's tuned well. Stock sleeves can handle a lot of power. Block guards are crap and don't do ---- anyways.

Your setup should be fine. I ran 12's in my stock d-series coupe, so I would expect 11's with a b-series turbo setup.

Re: Joined the 400hp SOHC club...on vitaras!!
 

niceeeee...do u plan on doing any head work in the near future or do u plan on leaving it as is...either way its sick...good job on the #'s dude ;D

Re: Joined the 400hp SOHC club...on vitaras!!
 

nice numbers

Re: Joined the 400hp SOHC club...on vitaras!!
 

thanks guys!

i do have a ported and polished head in my garage...im set on a zex cam, and prolly the edelbrock intake manifold...im still undecided on that...i would like to hit 450hp, i think its possible...

this setup has also been running at over 20+ for over 9 months now!! i used to drive it daily until i bought an accord about 2 months ago...so yes its uber reliable, and has barely any issues just normal maintanence you would expect from a build like this....my timing is set at 6 degrees and i street tuned that with a homemade set of det cans so im pretty sure that my tune is on the conservative side and that is to ensure this motor stays around for a while...

stock sleeves seem fine to me ive seen over 500 made on d-series sleeves...there are alot of other weaker components in a d motor than the sleeves.

Re: Joined the 400hp SOHC club...on vitaras!!
 

It has been running for 9 months like this and still counting... O0

Re: Joined the 400hp SOHC club...on vitaras!!
 

Nasty D, serious props.

Dynojunk operates by seeing how quickly engine can accelerate against a load. It is not able to vary load or hold engine @ fixed rpm aka "loading dyno" and that makes it useless to tune part throttle. You still spool on a Dynojunk just fine.

Re: Joined the 400hp SOHC club...on vitaras!!
 

That's what I would have went with if I was building my d-series motor up.

Re: Joined the 400hp SOHC club...on vitaras!!
 

oh ok i see what your saying there...now since i waited until like 4500 to hit full throttle on the dyno that would most likely affect my spool time and also where i made peak power on the chart, am i correct in saying that? on the street if i punch it from say 2k i usually get 7lbs by 3500 and full boost by just over 5k but thats not what it shows on the chart and thats why im catching alot of flak about it only have a 1k powerband....i guess i should have got on it early to see the full power band...am i correct in this thinking? like i said...dyno n00b.

Re: Joined the 400hp SOHC club...on vitaras!!
 

Put it in 3rd or 4th gear and go WOT from 2,000rpms.

Re: Joined the 400hp SOHC club...on vitaras!!
 

i hereby call this thread... inspiration... sohc owns

Re: Joined the 400hp SOHC club...on vitaras!!
 

man, thats awsome. Im tryin to convince a local guy to keep his D in his AWD integra. Hell, even if 400 is a rare case, it sure does mean that over 325 should be pretty easy to obtain.

Maybe a missed it but what turbo are you running?
