kinda new to the forum .. just curious if there are any fast third gen turbo iroc's on the forum ???

 

Yeah there are a few...how fast is fast?

I've done 9.72 at 142 in maryland and 9.86 at 141 on pump gas at my hometown pittsburgh track. Mild 401sbc twin 60mm turbos EFI

superirocz has been 9.7's at over 147mph. 406sbc i believe with twin 70mm on drag radials...street trim

leeperryracing is building a twin 76mm 401sbc that should also be deep 9's with 8 second capable power.

fast82z has a 406 with a single 91mm setup coming along if not already done...it should be pretty bad *** but not sure where he is with that setup. I think his old 383 with 91mm went 9.4's at 142..more of a drag setup on his car but nice setup nonetheless

I think we all could get 8s in a more drag setup with good gas and more boost. I've only ran 15-16psi and pump except for a bit of 110 in maryland to experiment. I'm going twin 70mm's this upcoming year so hope to see more fast times.

 

those are some nice times for pump gas street cars ... you are going from twin 60's to 70's ??

 

Orr's car is sick as f&&k...that is all haha

 

his car looks pretty bad *** ... cant wait until my twin turbo iroc is done ..

 

going from 60's to 70's should be a big improvement.. back in 2000 i had a twin turbo gn with a stage 2 v6 with twin 60's and the car went 8.70's@158..the next year we went to twin 70's and we got the car to go 8.15@173 by the end of the year...spool up was a little slower though..

 

See I thought the 60's had alot more in them but everyone I know building 400 inch motors or larger, either sbc or lsx were using 70's. I want to go 8's and I know 70's have enough to support 1400hp but just wasnt sure how far I could go on 60's. The car didnt pickup as much as I thought it would going from 12-13 psi to 14-15 and then to 16-18 but it was abit rich on the higher boost levels. I got small heads on the car too so that may be hurting things abit.

did you have the same turbine side? My 60's light off in an instant, makes it undriveable on the street from a roll below 60mph. Alittle lag would hopefully help it "roll" into the power and keep traction

 

i honestly cant remember what exhaust housings i had ... i know with the 70's i was able to run more boost ... i ran vpc16 and 36 lbs. of boost with the 70's ... i cant wait to see how my promod 91's spool...

 

mine is coming together nicely, just got my th400 t-brake valve body from "fast383" here on the boards, he works for transmission specialties...no BS, he'll hook you up plain and straight!! Pretty much identical motor to Orr89RocZ down to the shp block, twin 76s with .81 ar housings, 9:1cr, blow-thru carb on e85(no IC), will run a water injection kit later on if deemed necessary. Planning on running 7-8psi per turbo and shoot for mid 9s or so with 3.23 gears and 28" tires @ 5280ft altitude which royally sucks for racing!!!

 

I think the cars spoken about on here are more steet then race cars witch is very cool. I ran my car with the 17s on all 4 corners and still run the kyb gr2 shocks and struts and stock iroc springs etc.

I will be putting a new set of heads and cam in my car this winter along with a T-brake to up the ante . I have a nice set of heads for sale like new

 

i love fast street cars,especially turbo cars ... when i went 8.00's with my twin turbo t-type it had factory leather seats,all power ,full moonroof,all factory steel except hood.. my new twin turbo iroc is all factory steel except hood, 3300lbs.,drag radials,no wheelie bars and it should go in the sixes and over 220 .. i know its not a legit street car like your guys's but im trying to keep it as street looking as possible , except under the hood..

 

please keep us informed on that build. Thats a tall order to do 220+ You must have some budget

 

 

 

its a all aluminum 548 with twin promod 91 turbo's .. there already 3 or 4 guys that have my combo that have gone 220+ in the quarter so i hope im right there with them .. as for budget this is my fifth turbo car that ive built and i have no idea why i sink all this money in these cars ..

 

 

like i said before its all factory body panels ,factory floor,factory glass,factory dash and door panels with custom carpet ..besides the wing and dual chutes you'd never know how fast it was going to go ..

 

i saw we take that wing and shoots off and lets go make some money lol nice car man.. wish i had that kinda $ to drop.. im just starting my lt1 swap.. maybe one day ill be able to procharge it.. lol ill take the easy way out for boost

 

Very nice setup, what are doing up front with no inner fenders and where to bolt a front clip to that?

 

As said above, my 91mm on the 383 a couple years ago made 9.4's at 142-144. Never got spooling and traction to cooperate together with the altered setup and the 406, but with this and a tighter converter I got 146mph out of 15psi. Converting to twin 70's this winter that hopefully will solve the spooling and traction issues so I can easily crank out the 8.90e.t. that the 147mph suggests as well as plenty of growth to go faster. Don't think I'd really call my car a "street car" although it can be street driven and runs on pump gas, but I do call it a sleeper since it looks stock other than the roll cage or equipment hidden under the stock hood.

 

all new tubular bracing has been made to bolt the factory front clip back on .. i saved alot a weight and made the turbo install alot neater..

 

my dad races outlaw 10.5's and is in the sixes. 525 big block no turb nitrous.. point of this post is it ought to be quite some fun with no wheelie bars lol thats a nice *** car ur bulding tho. ive just started my twi turbo car. nothing nearly as nice as everyone elses but fun.

 

my car has been 135mph in the 1/8th so far at 17lbs of boost with a
1.5 sixty foot still dialing it in .....
BBC with a pt106mm stock suspension drag radials switching to e85 ..

wow that orange car is a beast!

 

xdamxincx,

That looks brilliant!

 

ray jr and xdamxincx
What size drad radial are you running ???

 

im going ro run the mickey thompson 315's ..

 

i run 295s now gunna try and fit some 315s for some street play.. it has a front half mini tub.

 

And I only have 1

Soooooo, is it weird that I'm slightly turned on right now?

That is one awesome looking set up!!

 

thx for answering my question. I was curious on what size drag radial will fit my trans am with minitubs.

 

my camaro is also just mini tubbed with stock frame rails ..

 

I like the turbos out in front like that. With my car I would reallly have to move the radiator/fans up under the nose to allow turbos to sit in there, but then again not sure where I'd put the intercooler.

 

is that your garage because if so i see we have some sort of 68 camaro and an elcamino of sorts

 

ray jr- your engine picture is now my inspiration for my future build. fantastic job!

 

Ray Jr.. That is awsome! Nice looking setup.

I'm the only V6 on this site.. Got a buddy with another Buick Powered Iroc that's been 9.40's
Hope I can get some single digit passes still on pump gas next year.

wat kind of intercooler are u going to run if any? a big old ice water intercooler in the passenger seat?

 

 

looks pretty darn good

 

would twin 50mm's be a good size for around 700-800 hp range?

 

orr's has twin 60's and makes 850 i believe i read somehwere. theres ppl on theturboforums runnin smaller ones. good site to check out for turbo related topics.

 

do you know what psi hes running to make that?

 

look up at his earlier posting he talks about them. click his fquik link in his sig for some more info on it. and back in the main section of the power adder forum he has posts in multiple threads with info and such

..post number 2 up top on here^^^

 

yeah....your not the only v6

 

maybe he didnt see the whole section labeled v6. i could see where he is coming from

 

twin 60's made somewhere north of 800 hp on motor on my car with plenty of room for more. They should be good for 1100 or so depending on motor combination.
Twin 50's pushed right could do 700-800 I think...but be alittle on the smaller side. I ran 14-15psi to be somewhere estimated at 800-850. Its 650-ish whp on mustang dyno on loose converter. Cant wait to dyno it again with the newer converter

 

ha that would be understandable for you...however he posts in that section

 

lmao now i wonder y he said he is the only v6? maybe meaning on this particular thread..

 

haha who knows....i mean just because his is the fastest v6 one(right now...that could change) and was in a magazine doesnt make it the only one ha ha ha ha, either way +2 for v6s on the thread

 

That orange looks killer. I was looking at a dark orange for my car but wasn't sure how well it would turn out. What color is that? Oh and the turbo setup is sweet too. IDK how I missed that lol.

 

Dang I had to adjust my pants when I saw this pic.
