Had a great day at castle comb today (rally day) an after going out for a blat with Porkie in the 3dr for the 11.30ish session i was on a high all afternoon dam that things quick just seems to have endless amounts of neck bending accelaration had to be 1 of the quickest cars out today... Thanks again m8 very much enjoyed

 

Was a good session until that Mk2 spun

 

How did Lee get on with his new turbo?

 

Went very well all day Had a bit of surge out of 'Camp'

 

chip


he is delighted that he took that stupid gt35 off that turbo really is good on bigger CC's well over 2 litres

personal think that the GT35 on a 2.0 litre is a waste of time the Gt30 better suited the 2.0litre engine he proved it today on track

he said he should have done it yrs ago

marco

 

Marco, glad to hear it, ive been nagging him on and off for a while, so I would have felt a bit of a cunt if he put it on and it was shit, although im sure me nagging him wasnt the reason for doing it of course.

Richie, im sure a bit of surge can be relatively easily mapped around

 

How much power does Lee's car have? Seems to be at most track sessions with out fault all the time.

 

dont know mate he is on gt30 safe to say 500+

 

Thanks mate.

 

Cant comment on the gt35 but was going very well with gt30 hardly any lag that i could tell

 

Surge? BOLLOCKS....

It doesn't surge one little bit if you floor it in 5th at 3500rpm let alone at 5000rpm in 3rd!

he has a Tiger stripped 'Corsa Combat' Saff..... and so its clear the Geezers got SHIT in his ears as well as his fooking eyes!!!

The GT30 is the soooooooooooooooo fooking good. Suits the engine soooooooooo well, as Marco said... should have done it YEARS ago!

Enormous power band now!

 

now now lee, tis only the tinternet

 

See no evil, hear no evil Richie knows I am only joking with him!

 

Knew itd be awesome with a GT30

Cracks me up these days everyones hearing phantom surge Now every time someones feathering the throttle etc so you get some chatter someones like "ooooh! surge!"

 

Stav.... I now have the worlds first Sierra Automatic trackcar. You just select 3rd gear and drive it like a big go kart! 2 gearchanges the whole lap of Combe now!

Pulls HARD to 8300rpm no worries PROPER Turbo

Even you will be SHOCKED at just how different the engine is now!

 

Glad it worked out Lee. You still running the same boost?

 

Car was looking mighty fast Lee.

Can i ask for some opinions regarding turbos, im building the zetec T engine at mo and the turbo needs to be decided upon.

For a power delivery of around 400 bhp would you recommend a GT28 or a GT30.

 

LMAO @ "Phantom surge"

Glad to hear its going well Lee.

Must be nice to put your foot down and something actually happen straight away, I thought someone had nicked the turbo when I drove it on the GT35 and put my foot down at about 3500rpm

 

was looking good mate. Goes very well. Was trying to find you in the paddock, but only saw the car

 

Depends what GT28, as most wont go near 400bhp.

 

i can pull away in 5th in mine lee

ps 6th is shit unless your doing above 90
think i need to change the diff to 3.9's of 4.11's

 

i remember asking about this before i got my T34. I think stav said that a GT28r wasnt a "proper" Gt28 or something. If you run any of the GT series, do you need a custom manifold to suit to get the best from them? im not too clued up on GT's

 

"Disco potato" or "GT28RS" is the term you want to be banging into google for the right blower for 350+, but 400 is really pushing it.

 

Its the big decsion of choosing what power figure to go for..

Run 370 bhp on a Gt28

Or go for 400+ on a Gt30.

I cant decide at the moment.

 

Eh? No i didnt.

28RS would be lucky to do a genuine 350 imo.

but there are much bigger 28 based turbos that do 400 odd.

 

Big thanks to Lee for taking me out in the 9.30 session, fook me that car is awesome, driver aint to bad either lots of chaos before we got on track, spiky left my jacket on martins trailer i had to borrow his misus jacket, then i couldnt adjust the harness, marshall had to do it, felt a right dick. Got 4 laps in and i wont forget it in a hurry, was buzzing all day. Cheers Lee

And compressor map:


So as you can see, you will be off the edge of it well and truely at 400

A 2871 one though, is very comfy at 400bhp:
