As the Street Racing Scene gets fierce.... Its time to Step up..
 

Our local street race scene has been getting some quick cars lately.. Lots of all motor guys running large shots, which has made it difficult for me to beat on the street since I have such a huge traction problem. So, one night I got just reallly really pissed, and wanted to figure out a way to get some traction.

First..

https://www.homemadeturbo.com/ride/89si2/boostcont.jpg

I had to figure out how I could get some lower boost going in my lower gears. 12psi is simply unreasonable with street tires in my car, I could smoke the living ---- out of them 1-2 and half way through 3rd. So I devised a little setup, I used a Sol Duty Valve on a 03 Kia spectra, its basically a 1 way electronic check valve. I hooked this up branching off my boost controller line going directly to the wastegate. So when the valve is open, the wastegate gets a pure source from the manifold.

So basically, I put a toggle/switch off the shift knob, when the button is pressed in I get a 6psi (wastegate minium) and when I let off I get my full 12psi. So 1st gear, 2nd gear hold the switch, and as soon as I shift into 3rd let off the switch and I hit 12psi :) This is by far the best modification I have done, it works so so well!!!

2nd..

At 6psi in 1st and 2nd seemed ok, no traction problems, but not nearly as fast as I wanted.. So I went ahead and put in a full ignition setup, MSD 6BTM, Blaster Coil and MSD Cap to help out.

3rd

The car still felt ----- at 6psi, so I went ahead and orderd a Lightweight Race crank pulley from RVM performance.

This thing is so ------- light, its crazy. I swear it doesnt even weigh 1/2lb. I had to use a custom sized belt though. This really helped up spool time.

4th..

The CUMHO Supra 712's just dont ------- cut it street racing, so I slapped on a set of Black HX 14in wheels w/ a set of (very used) Nitto Drag Radials. Its still a bitch launching with these.. but better than the radials.

Last.... But not a performance mod. heh

My Sparco Race Seat... I figured its been sitting in my white car brand new for almost a year, I could atleast try the fucker out, haha.

Very nice:) I bet its fun as ---- to let it hit 12 PSI on the fly;)

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

wow, that's impressive!

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

thats what i need to do, i have a 90 crx d16a6 t3/t04e 12psi and cant get traction in first or second im on crappy tires for starters. also a lsd would be nice.

and with a pinned b18c1 swap coming soon i really need to do something about it.

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

Thats Badass... is this going to make it's way into the tech projects?

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

he just told u how to do it, put an electronic check valve inline so the wastegate dosent see boost and opens at the minimum spring pressure. then when you want full boost close the valve and let the wastegate see boost.

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

at first I thought jeff was going to tell us all to keep it safe and take it to the track, like a sell out. Then I get here and I realize he did the write up I wanted so much. You know jeff, you aren't such a bad guy after all, I'll stop telling everyone in new mexico that you are a wanker.

Surgeon's General Warning : Using surgical gloves may lead to smarter thinking and better boosting ;D

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

"The push button pimp" Who the ---- thinks this ---- up? Don't tell me you still have a job AND come up with this ----. That's the best invention I've ever seen on HMT. I still wouldn't suck you off, though. ;D

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

i'll have to read that again, and take it all in, but that has to be about the smartest ------ thing EVER. Jeff, your like the ------ einstein of turbo performance. seriously, that is super trick. definately a gold star on your report card this 1/4.

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

Well, I didnt get any gold stars tonite... I think I cracked a sleeve or broke a piston tonite.. shes smoking really really bad. No road trip in the crx next week :(

But as always, when I break something, it always gets better :)

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

damn jeff your car was smokin a lot. but atleast it happened during a race :) got some good pictures of your car engulfed in smoke :P

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

you post those pics, you die! lol :-X

I was racing Scott's GSX 600 on the freeway.. lets just say, he didnt pass me, and I didnt pass him.

----, I sure hope I just broke pistons..

PREY's TO JESUS, PLEASE LET THE B20 SLEEVES SURVIVE

??? ??? ??? ??? ??? ??? ??? ??? ??? ???

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

Werd, we were wondering if you got home okay .....:(

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

take some pics.. and post those smoking pics up man!

----, I sure hope I just broke pistons..

yah.. JUST lol

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

:( :(

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

that's a damn shame. losin a good motor is like losin a member of the family. :-[ saw some v6/civic pics in your post, heard about that... it's better on width, but tryin to shoehorn it in the depth is tite. i can't wait to see what your gonna do next.whats that sayin..
if at first you don't succeed, try try again.

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

umm that’s not that revolutionary of an idea, it’s just a 2 stage boost controller, his way is just cheaper.

that sucks about the b20, did you do all the machine work on that engine after posting it?

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

no no no, it's if at first you don't succeed skydiving is not for you.

I think you should build an odysee

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

I know he just showed how to do it, I just thought it would be cool to have it in tech so newbies and such wouldn't have to search for this post. Plus maybe part #'s etc. would be cool. And there hasn't been a tech update lately. But back to the issue at hand, sorry to hear about the engine Jeff.

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

jeff... is that button a push and hold for voltage or a toggle push button? if its a push and hold I would change it to a toggle because it might be hard to press when shifting.. you dont want to let that go while going into 2nd expecting only 6psi and get 12.

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

that IS sweet...

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

Is that your NOS button on your shift knob??? If so that's the dopest setup I have seen. Nice work man.

Scott

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

did you read the first post? ::)

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

thats a pretty sweet ass idea.. is it hard to push the button while slammin through years? or would some lil ass trigger or somthin work better? who knows ur invention ..lol ;)

Damn, creative ----. I bet a lot of people would have never thought of that.

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

so did you get beat by some cars?

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

alright FOOK, where do i get that little thing-a-ma-jigg??

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

I actually bought the entire assembly off of an HMT member here in OR. its a basic hmt MBC and an electronic solenoid that closes and opens the line. the rest is just wiring and a toggle switch. you could do it like abaz did, use any mbc, get a solenoid off of something like he did, and then its a few vacuum lines and tees, this is basically the same thing.

when its closed, it closes the path from signal to wastegate direct and forces the signal thru the boost controller, when its open, obviously it lets the signal directly to the wastegate and bypasses the boost controller.

WERD!!! At least we know bub is a reader, so that's a plus, even though he revived a goin on 2 year old thread :D

Hey outta curiousity, SiturboD, what page did you find this on, or did you do an unheard of search :o

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

yeah thats nuts who thinks of push buttom

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

omg this is old... still best damn mod I ever did to that thing, ;)

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

yeah SiTurboD joined up, grabbed a shovel, and started digging up dead threads in the databases graveyard for sure on this one.

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

what the ----?

i posted this ---- in the F.I. forum like 5 hours ago

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

haha wtf?...i wonder if this guy is still around. when i first saw this i was like oh damn he got his car running again. then i saw onyx post. so i checked the date and sure enough it was back from 03. i say jeff make a new rule stating you cant bring up threads that are dead or they should be banned. :D

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

Abaz, Do you have a part # for that check valve?

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

no I dont, but I can get it for you if you want. Just hit up some local junkyards you will find tons of electronic check valves out there. Mainly used in Evap systems, some used for other things.

Re:As the Street Racing Scene gets fierce.... Its time to Step up..
 

go grab a black mystery box out of an 86-89 accord, just loaded with all kinds of solenoids etc...
