As title.

would like to know your opinions of it in regard to spool up, esp compared to the smaller housing like the .83 or whatever...

STILL not sure why some rate them at 700tho, the compressor is only 65lb/min, and thought it wa roughly 1lb/min per 10bhp...

Thanking you kindly.

 

it is, but then if u look at a t34 comp map. its only about 300lb lol

 

queue phil

 

Ive got one on my car steve But all i can compare it to is my old t4 which used to make full boost by 4k but the gt35 dont make full boost until 4.5k

 

Think Rod ran a 1.06 Steve

 

Steve, its more than 10bhp per lb (10.5 is far closer in most cases and sometimes as much as 11bhp if you have enough ignition advance and a decent quality fuel), so 700bhp from 65lbs is perfectly realistic, but also you should know that all those quoted figures for flow are fairly easy to exceed on most turbos, they tend to be very conservative.

 

Aaaah thanks. Got 3litres and a 100shot of gas to get the fucker going so the big housing shouldnt be a prob.

Hopefully by end of this year or early next youl be seeing a S13 in the 9s and pulling some class wheelies off the line

 

Steve,

I know it does not answer your thread title question, but I have posted the manafacturers spec/figures below

One thing I did find out when going the GT35 route is that most tuners are very cagey when advising about the "correct" exhaust housing size......I deduce from this that they (or their customers) have found out the "hard way" (i.e. expensive) what works and what does not work on a YB engine.........

Why only 100bhp of nitrous?

Surely you would get far better results with more gas?

At least you have seen the light and are using it at all though!

 

Absolutely fantastic signature you got there Stevey boy.

 

Doug, those figures ALL have 60lbs per hour flow, and yet make wildly different horsepower figures, so im afraid wherever you got that from, its not correct, it simply cant be.

 

From here Chip:

http://www.turbofast.com.au/GTseries.html

 

Or 60lbs per minute????

 

Maybe they are quoting a max theorectical flow for the compressor, as opposed to the actual flow the turbo will achieve with the exhaust housing used?

Either way, its very misleading.

 

oops, cheers for spotting the typo! Ill take that as a well deserved

@ 60 per hour it would only make about 10-11 bhp max, PMSL

 

Soon as i saw what doug posted i knew it was Ray Hall Turbos.

Chip- I like nitrous. Hes only gonna go about a 100shot for now as we talking well over 600bhp before the gas and its far from a big spec engine, itl do the job tho

Might do gas on my car one day, but not yet, should make more power without gas than the car in question with it.

Not as light tho

 

Steve, is the Ray Hall Turbos info not accurate???

They are one of the few people that put up information on the entire Garrett range on the internet..........AFAIK even Garrett dont do that

 

Doug, like i said, i think perhaps its a theoretical compressor flow rather than flow for the turbo in use, so not innacurate, just irrelevant!

 

Chip on the subject of gas its somethin Ive always wanted to have!

whats your expoerience with it on the 200sx!? is my enigne to choclaty for it!? i really have no interest in doin internals as i never plan on goin more than 350hp!(other than head gasket)

 

Ive only ever driven an S13 on gas, no other 200sx, so im not sure TBH mate.

The S13 was fooking hilarious, it was a right old shitter with a big kit on it, and it roughly doubled the power and more than doubled the torque, went from slower than an astra GTE to quicker than a skyline GTR at the flick of a switch

 

Fair enough!

Would be a long way of b4 i even thought about doin it! but just thought i would ask! seeing as u quite knowledgable! & i can quite obviously not even spell knowlegable!

 

Do you have a way of retarding the ignition timing when "on gas" on your car, like a programmable ecu or whatever?

If so it will drastically increase the amount of power the standard pistons can handle.

 

Not entrily sure to b perfectly honest m8!

It runs a air flow meter!

U can chip the ecu & u can also wire in a fuel controller in2 the ecu to adjust fueling not sure if u can adjust anythin else!

 

Doesnt sound like it then mate.

TBH i would leave it alone if i were you, you want a reliable car and standard ones tend to do that better!

 

Its using a standard Holden VL Turbo pistons, crank, and rods, they good for 750bhp, and a fairly std RB25 top end, but we a bit sceptical about going further than a 100-150shot, no need either really I doubt.

Dont know the exacts of the ecu or nitrous setup as yet, but its a fully mappable ECU yea.
Being done by someone whos done it all before on the same engine etc, jus not in a S13

Wheelies, 9s, and 140 terminals Should end up holding the S13 record for 2 different countrys

 

Yea think standard is best to b honest!

I love gettin in2 my car & it starting 7 workin!

The SX is all about pimpin! & 4x4ing!

 

Steve, i take it thats on wrinkle walls then to run such a quick time with such a low terminal?

 

Chip - Yup

Got a set of 4 for my car too

 

I hope your clutch / diffs / shafts / transfer box / gearbox are all made of something from mars then, lol

 

Ive seen a big heavy R32GTST4 with totally standard box and diffs, running in RWD mode and running wrinkle wall rears, run consistant 10.1-10.2s at 135-140mph, so i doubt a far lighter car with stronger trans will have serious grief

 

wrinkle walls, sounds like the dodgy decorators have been in again

im guessing its a drag tyre that has a collapasble wall so as the wheel starts to turn they tyre is still stationary to aid grip, bit like a fluid flywheel clutch (as used on busses) to make it smoother instead of just lighting up the tyres??

 

Yes mate, thats spot on.

Its also about contact patch as well though, the tyre collapsing at the start before you launch means more rubber touching tarmac

 

cool
