What power would be expected from a 35' at 15-20 psi? been researching and found a cheap variant ( not best at all but worth a try) which is a t70, 0.68 ar, similar to a gt35 but smaller, so like a gt30-35.


Been comparing some specs of different vehicles with this turbo at different boost levels, found on on a rb20det skyline running 14 psi which produced 330whp.... for not much boost thats alot of power dont you think? around 370-380fhp.

cheers!!

 

where do they make the power though, have you ever actually driven a car with a gt35 on it? for a road car the best place for a 35 is in the bin lol

 

haha nope dont think many people have drove a car with a gt35 on it, would be an experience though!

i just want to build a norweigian sounding 3rd gear wheelspinning flame popping weapon lol

Nothing till 4500 rpm then a lovely break of traction and scream from external wg!

mates got a gt35 on his evo and that seems to spool very quicky, alot sooner than my t34 to be honest, got a tiny ex housing for such a big turbo though.

 

here il show you the turbo il be getting, you can rip shit out of it if you like lol.. its just something i want to try, will probably last a moth or so, the car wont be used everyday anyway!

theres horror stories of these cheap turbo's falling apart and launching shrapnel into the engine, causing terminal damage, just be careful with em bud.

 

aye, will do, either way if anythin happens id save for a 200 bottom end and do it properlly, Just want to do something different thats all, i always have

ive had a to4e before (t3/t4 .50 ar) and that was fine, ive heard the main thing that happens is seals or lack of balancing at manufacturer hence destruction, ive seen a few fords in magazins though with cheap variants of turbos..

 

My mates got an gt35 on his 3door, goes well.

Here is a new Norwegian monster engine procject, sorry for Norwegian tekst

Is it Strokered Dan or still 2litre??

 

yes Pete, its stroked, 2.4.

 

With the right cams in, a ported head and some decent mapping - a 2.4 GT35'd evo is an absolute animal!

I remember supporting one at the Nurburgring once and it was described as "like wrestling a lion in a phonebox"

 

its a big spec engine, came out of a track car that was doing high 700's apparently, i dont quite know the full spec, i have seen the head and the ports are seriously worked, has a custom jenvey inlet too. Been mapped by Andy Nicholls, struggling to get power from it though, boost control is all over the place, and when it does run properly it still doesn't go aswell as it should.
Want a job fixing it, Will? lol

 

High 700's from a gt35 ?

 

no, was on something else before, didn't buy the turbo with the engine, using his old GT35 on it.

 

Ah ok

 

think that may of been stretching a 35 a touch!

 

Just a touch lol

If you had said yes the piss taking would have started

 

lol, i might be thick, but im not that bad!
as i say, i really dont know what turbo was on it!
Fuel system was fairly hefty though!

 

id have said it would be laggy as fuck without useing it to its full protenchual its a 600bhp+ turbo and 15 to 20psi of boost is such a small amount i run 38 on a gt30

 

too high boost kills engines though....james what power have you made at 38?

 

Go for a run in MADAdes car & you would stuff that remark up yor arse , simply the fastest road car out there. Yum had a GT40 & most thought that was silly fast on the road. These silly comments about badly Specced surge monsters are really annoying if you have a Tuner that can make them work .

 

Its an m.a.d 500 set up and it hasent killed mine in the 3 or so years its been like that!

 

thats what i was thinking... Why the fuck can swedes and norwegians have 600-700bhp cossies built cheaply but they work, and look and go lethal, yet to get 400bhp differently from a yb in the uk is a mission?! i just want a external wg and a different turbo than a t34, t4 or a gt28rs ( all expensive way over priced now days imo)

i dont mind lag as long as it comes in with a bang and kicks your head in lol

edit * just looked above!... i always had a spot for msd, but now i think im turning to the m.a.d side... gonna ring mark shead tomoro i think!

 

i guess we have different views of a road car, mines about 400bhp tops, so i will stick my comment thanks

infact the best cosworth road car out there imo is a standard small turbo escort

Dont get me wrong, if your after 600bhp+ then the 35 is a good option and works well on the correct spec engine, but the thread starter isnt after 600bhp, he plans to run it at 14psi. and for that power level he would be much better off with a smaller turbo charger imo.

i would be genuinly interested to see a gt35 car against a small turbo esc cos in 5th gear at 20mph, and both floor it. i wonder which would be the most driveable on the road?

 

A 2.4 Evo lump making 700s would be most probably on either a GT4094 or a GT42R variant...

What boost control is it running?

Drop me a PM if you like as we're taking this thread on a tangent

 

why would u be in 5th at 20 anyway lol pointless thing to say and small turbo escorts are slow why? because the turbos to small to make any power lol and dosent rods make full boost at 4200rpm thats hardly laggy is it and his turbo is much bigger than a gt35!

 

drivablity, im a lazy driver on the road

my last saff box broke at 30mph in 5th after coming off the motorway and rolling down a slip road, gave it a bit of throttle and bang oops.

i dont find small turbo escorts slow really, for road use they are ace little cars.

like i said, on the right engine i find the 35 good if its power you want, but i dont see the point running it at 15psi and living with its downsides when a baby gt30 would be a better option at 2 bar, using something like a gt35 to make 370 bhp to me is madness.

its only my opinion but i generally pick a power level, and then chose the smallest turbocharger that will make it reliably, and ususally that means it will ultimatly be as drivable as possible.

 

ive used a couple of these before mate in the t3/4 variant with .63 ar exhaust and .50 ar inlet, worked well with me, no probs at all

 

yep it is totaly pointless at that power will only make the car slower in the real world on the road low down in gear but i dont think they are laggy turbos when used right

 

And you are correct, as are all the car manufacturers who spend billions on research and then do exactly the same thing. Thats why you work for me James, you are very very good at what you do mate. Dont feed the trolls. LOL

 

I built and ran a 2litre ZVH with a t34 .63 running 15 psi boost, TBH the turbo was too big and the car would of been quicker with a smaller turbo and maybe a bit more boost. So i totaly get where you are comming from stu, what really matters is what it drives like on the road/track IMO

 

power is like cock size lol na mate not if your into haveing a fast car people only say that if they dont have a fast car! lol and if u think big turbo = not good on the road maybe u should change tunner lol

 

i can tune my own cars mate, i need not a tuner to do it for me! and my car is plenty quick enough mate, it just doesnt have an unnecisarily oversized turbo! and its all very well having 600bhp for 1000rpm between 6 and 7k, but how is that any use on the road? a good turbo diesel would beat it on some of my local twisty highland roads!

 

havEing lol

 

lol ok then mate but what about when they make between 500 and 700 bhp from 4500 to 7000 and 500 to 650lb ft for the same rev rang? and bolting bits on isent tuning is it lol anyone can do that the hard bit is knowing which bits to bolt on so they all work well togther and how to set it up so the bits all work well togther!

 

Thats good im sure, but then it all depends on turbo choice as mentioned, and sorry i meant tuning as in mapping as well as engine building, i do it all myself im sure there are good big power setups out there, but the OP is on about an ebay turbo that is going to be well laggy and not make much power low down.

 

yep i know mate i was commenting on other peoples commens that big turbos are laggy and no good on the road which is not the case but yep the turbo stated will be no good for what he wonts!

 

cool

 

i just want a norweigian cossie lol!.....

Big bine, external gate, downswept 3" pipe which is heatwrapped,swedish plenum, standard lattices with crap rear tyres, and 400 odd bhp

things of bringin lag down surely would be

swedish plenum
tubular manifold
3" boxless heatwrapped exhaust
fine mesh over inlet of turbo instead of filter

sure with a live map at 20 psi that would go well?

 

http://www.youtube.com/watch?v=8Fm7w...eature=related fast forward to 2.30 minutes odd

then this

http://www.youtube.com/watch?v=-Q1z_...eature=related

this is only 350-400bhp
holset hx35 is bigger than that t70
