Dont matter if your runnig the .86 housing as i think not many would run the 1.06 but i have to because of the higher comp ratio i am using I guess i will have to add on another 500rpm spool up time!

So when does yours spool up because i hear it is better than the T4?

Also what BHP did you make and at what boost pressure?

.....i guess i will make around 630bhp @ 2.5bar on pump fuel and alot more on 102ron @ 2.5bar as i understand you get more gain on higher comp than lower comp from the race fuel....obviously this is subject to the engine holding together and my head being ported correctly..as THAT is eesential for making the power without over boosting the turbo! Plus i am not garanteed goin to the dyno instead just live mapping on road and final @ Brunters as this will save me ALOT of cash!...I will however put it on a dyno pack if it dont go to dyno just to shut the haters up

On the road i think i am goin to run it @ 500bhp so what boost pressure do you think i will achieve that at? (The reason being i want the engine reliable so its only got to do a couple of top speed runs @ monte boost to acheive the 190mph plus target...plus lets face it...over 500bhp on the road is it nessecary..infact is over 300???!!)

1.05 is a hooj housing for a 2litre, ive seen 3litre Supras in the USA get 900+bhp with .86 housings, but its one of them trade-offs, as a big housing like that will really lower your pre turbo backpressure

Providing the idiots DONT start posting crap cause of the thread starter, this could be a good post

Anyone have any real number or info on the difference in spool up time with a turbo, JUST changing the exhaust housing size, from a small one to a biggun?

Phil,

Vince (Universal Turbo's) quoted me 24 - 26 LBS PSI for 500/520 BHP with a GT35 - but that would have been with "typical" a .86 housing

Edited to say:
Some of the EVO boys (high comp: 8.1:1 ish) are using the equivilent HKS turbo (slightly diff exhaust housing) and getting 500 + BHP at 1.6 BAR.................. ..........makes you sick, dont it?

ADUSR33

phil who cares get a ps2 and get on gt4

Jon(m600)

Hi phil my engines going on the dyno hopefully within the next couple of weeks,and its using a GT35 with a 1.06 housing and im hoping its only gonna be as laggy as my old t4 but with more power at sensible boost

for the untechnical of us why does your comp ratio mean you have to run such a big exhaust housing?

ImaRacing 700

As its gonna be running alot hotter than a lo comp and i can keep the temp down by running a bigger exhaust housing....thats all i know..LOL...its just safer...ok it means running more lag but the off boost drivability is what i want.

ImaRacing 700

PS...thanks for your input re rev range and BHP Porkie

Phil
Mine made 507bhp @ 1.2 bar if that helps.
Rod
ps. Prob is it feels so slow you think you can push it faster. if you have 640bhp no way you can run it with 500 its like pulling a Tanker.

What makes you think I have any experience of those exhaust housings?

and I was under the impression that this was an ImaRacing 700 specced and built engine?? you couldn't possibly want or need any input from anyone else could you?

take the turbo off then

Or put LOADS of ignition advance in

Phil ,

You soooohhhh could teach the following people so much....

Mark, Stu, Karl, Julian, Harvey, Ahmed......

Why do you waste your time selling german car parts

ImaRacing 700

Because i make a profit ????

Cosworth & SECS...go hand in hand...both unreliable pieces of shit

FYI, Ignition advance can actually reduce turbo spool up time
and may not make the engine feel any better off boost.

As an example...

Retarding the ignition around the 500 to 800 rpm before the point at which the turbo starts
to make 10 to 20% of its boost can actually decrease turbo lag.

Obviously these figures depend on engine spec and can only be
determined with live mapping and experience.

This is because more energy is allowed to leave the cylinder giving more energy to the exhaust impeller.
If advanced, the combustion is all but over reducing the available gas
expansion before it leaves the cylinder.

Yes you are correct again Phil i bow down to your great experiance of asking everyone what they have ,would,what you using, what do you think, etc etc,
Your gatherd knowledge must be greater than any cos tuner anywhere in the universe
I really hope your engine does the biz
Well lets be honest It should do youve asked every person avalible.
DIY What a joke
I tell you what i will put my shonky 31 year old 480 bhp Dolomite up against your car anywhere Top speed , Track , Santa pod
Im sure your 600 + hp could Kill my little 480 hp Dolopofshit
If thats your thing put your money where your mouth is
Ps it still dont SURGE

ImaRacing 700

ALG1K......yes to build any engine you need advice..but ultimately its my build as i have specced it..and NOT to an MAD spec sorry to dissapoint.

I never bet money as i have enuff already...how about life?

Ryan

can just imagine Mark phoning you up and asking "phil what do you i need to make 600bhp"

Alg1k

iTrader: (2)

Yes im sure your going to tell us the Real speck


I never bet money as i have enuff already...how about life?

Anything you want to bet dont bother me ,
Just hurry up !

Ryan

Actually phil, and this is a genuine question.

What in the Engine have "you" spec'd? without advice?

wimwerf

and your engine isnt a cos engine i guess.....

Alg1k

iTrader: (2)

Yes Phil what have you spec,d
Port sizes on cyl head ?
Diff combustion chambers ?
Camshaft lift , duration ?
Timing for camshaft ?
Inlet manifold volume ?
Your own ex manifold ?
Spec manufactured pistons to your dimensions ?
Diff width piston rings ?
Short , Long rods,
Crankshaft to your design ?

I will answer for you Phil
NON OF THE ABOVE
DIY

ImaRacing 700

DIY...means built and specced

Just to say Ryan is a COCK The property dealer who uses Discovery home and leisure for advice

We all need advice Unless you are named Karl.....The GOD of Cosworth.

Ryan

Phil it seems to work though phil

I seem to be doing ok for 24

Alg1k

iTrader: (2)

So you have designed nothing and copied everyone
I will say again
DIY
Didnt realize Karl was the god of cosworth
I just thought he was a knowlegble down to earth person .
Which you Phil are NOT
Anyway PM me if you want to see if your DIY 600+HP is faster than my 480 hp
Take a ride up to Hams hall sunday night on your moped and come have look at the competition

Matt

480 daz

and his port sizes are "better" too

none of the above

ImaRacing 700

ALG1K...i am the thickest,the most retarded,stupid person on God's Earth..and Karl claims i cannot achieve my goal...What will that make him *if* i acheive it

As for designing the engine...no i didnt,just specced it to what i think will work even though Mark has said he wouldnt do it like that So i hold my hands up no to DIY i am a fraud

So what you are saying is that DIY is actually designing an engine yourself from scratch ie making every componant aswell ....can pro tuners do that then?

Phil, Not a p*ss take, but out of interest, please could you please post up your spec for us

So just to be clear, this post was for you to get info from other people to help you.... BUT you are unwilling to give your spec
