How do you find the turbo performs? what sort of boost threshold does it have? and what sort of power/pressures are you running? anyone had reliablity issues?

..i dont think anyone recommends you run a GT series turbo on a yb without it being external wastegate.

Phil,

that is utter nonsense mate. There is no actual need for an external gate on a GT30

JonnyBravo

Marco Polo's GT30 is internal wastegate as supplied by Reyland

Speak to them as no doubt they can tell you what you need to know

K.Goa

I have a GT3076r with internal gate, APT`s ultimate internal gate in stead of the original garret one. Have high expectations for it, but havent tried it yet.

Dan

Sorry Phil, but your totally wrong there!

A mate's Dad who has a MAD tuned Escort Cosworth has just fitted up an internally wastegated GT30, recommended by Mark!

...sorry the tuners i deal with must have said the gt35 upwards and i just assumed they meant all of em

hi will the one on my car i cant really tell you anything because i haven't gave it any abause at all i will, once it's live mapped i dont have any serge issues when it comes on boost

it makes boost about the same time as my t34 with .63 but kicks twice as hard i have heard rumours they they do suffer from cracking the rear housing .............im not really botherd about that as long as it lasts a good while im happy nothing lasts for a long time in motorsport anyway i forgot to add the internal wastegate wont make as much power as the external one ..

the internal one is not as laggy as the external one, horse for causes and all that

you will have to show me next time at the RSOC meet at the greyhound mate, I was going to say hello Tues night, but I didn't get chance . Car looked stunning though. , although you might need to upgrade your brakes

You recon the GT30 is a good compromise then? thinking when I rebuild my escort it might be getting one

marco polo

iTrader: (1)

will there was cossie parts flying all over the shop myself and steve talking cossies all night (sad i know) did you notice why the back end was so high ? i couldn't be botherd to lower it because these are off the rs2000 mk5 and i dont want to mess about with the hight fitting them back on the rs2000 .........lol... i could do with bigger brakes my others have gone in for re-valving should be back next week

Stu.H

Stick the 35 on will

You'll need it



Actually, no, make that a 28

marco polo

iTrader: (1)

it should be called Black country& birmingham rsoc

RWD_cossie_wil

iTrader: (9)

thought it was just the stance, usually see 3 doors/saffs sat about "1 higher at the back for the handling people slam them on the deck then wonder why they understeer into oblivion

RWD_cossie_wil

iTrader: (9)

for the escort Stu, not the saff, besides, I will have TRACTION not a 320BHP FWD tyre smoke creation machine

Fiecos Dan

what are you after?

my gt30, made just over 500 bhp on road fuel on a engine dyno, @ 26 psi.

hits 30psi by 4000 rpm, and i still havent played with cam timin to improve that.

marco polo

iTrader: (1)

mine does normally sit on the deck but has all been set up to go around corners

RWD_cossie_wil

iTrader: (9)

sounds exactly what I want , although I will have to enquire about a huuuuge midrange spike, as a 500BHP/500Lbs/ft engine would be ideal - just want a huge midrange, the BHP could be a bit lower if I gain the area under the graph on the torque

marco polo

iTrader: (1)

this is how it normally sits




heres the turbo

Stu.H

looks nice marco, have to take me for a blat sometime

RWD_cossie_wil

not a fan of cat's eyes then marco?

marco polo

iTrader: (1)

hi stu

yea no probs will be live mapped soon by karly

K.Goa

@Fiescos Dan, sounds good that! what is the spec of your GT30?

Fiecos Dan

a Rough spec =

0.70 comp housing, 55lb comp wheel, 0.82 AET ex housing.

marco polo

iTrader: (1)

mind does not hit 30psi @ 4000k far from it , i wont know untill it's finally mapped

Fiecos Dan

What rpm are you expecting to see 30psi, lower or higher than mine.

marco polo

iTrader: (1)

well i would say a bit higher that would be no good for me , it would be all over the shop in the corners for me in a rwd car, coming on boost with that much psi

rapidcossie

Marco...why do you have a dipsick in your slam panel?

RWD_cossie_wil

iTrader: (9)

At a total guess here, I would say it's because he runs a big-wing gated sump, and if you use a dipstick it stops a gate working, so you have to use a blanking cap and just use the std dipstick whe you want to check the oil

K.Goa

@RWD cossie wil, how is the GT35 on your sapph coping with the ALS?

RWD_cossie_wil

iTrader: (9)

don't know, it's not built yet, , But I have heard that they don't like ALS at all, so I might have to change my plans

AndyRS

Thats just the reflection of Marco taking the picture

RWD_cossie_wil

iTrader: (9)

so, any more GT30 owners got any info?

GARETH T

PMSL thats funny,, sorry marco

cos47

Me and my Dad are just fitting one to his Escort Cos then it will be off to M.A.D for mapping so I will let you know how it gets on

Rick

30psi at 4k is less than a t34 63 makes surely?

marco polo

iTrader: (1)

Hi Euan

Wil is right i use a 7.5 litre gated system touring car sump and if i leave the dip stick in it stops one of the gates from opening , i just use another cut down dip stick and a dummy


marco

marco polo

iTrader: (1)

rick i dont know but when the boost comes in i only know from 1st if you know what i mean my t34 with the .63 use to start making boost @ 3k and this turbo does the same in 1st gear it comes on boost about 3k well it's making power it's hard to explain
