best chip for my spec???
 

right i basically need a chip to run my cossie under its current spec but who to ask????

T4 turbo
3ins ss exhaust
will run 803 dark greens
rs500 air box
rs500 type intercooler
engine is standard
L6 ecu

I'd try Stu@MSD first mate :top:

I would either uprate the injectors or downsize the turbo first, have you got a group a fuel pump ?
I would also speak to MSD about a chip, but you will need almost certainly to get it mapped.

MSD m8 they will sort you out .

T4 and greens? :eek: i hope its 8 greens not four :eek:

why???? talk to me here, whats so bad about running a T4 with a low spec engine????? this is my track car so it`ll live on boost

Would be so much better on track using a T34.48 with greens :top:

Steve.

Why don't you go for a T34 SETUP ?? with either a .48 .55 .63 housing, the .48 will be nice and punchy and works well with Greens and you could peak it @ around 30-32 psi.. you'll have a nice track car then :top:

your still not answering my question of why is a t4 on greens bad????

i spent over two year driving my last sapph with a t34(.63) on greens and the last few months on greys with a much worked engine so can you explain to me why this t4 route is bad???

Greens int he real world are maxed by about 330bhp no matter what people tell you.

My T4 car at only 18psi on a base map would eat stage 3 T34 and Greens cars alive.

On a T4 you want Grey of Siemens 55lbs atleast imo. T4 on Greys with a standard head should see around 400-420bhp depending on whats RR you go.

Choose a Tuner then ask them what they would advise. Stu@MSD, Ahmed, Or Karl@NMS are the ones i would trust. I would Change to L8 aswell as it allows you more options, and its a slightly better ECU.

T4 isn't bad on greens, aslong as it's 8 of the fookers.. :cry:

:cry: :cry: :cry:

Even better on 8 light blues or 8 Greys ;)

nash whats your spec budd???? i`m not after big power at the mo but i know with a t4 it has the potential for lots later on lol

T4, 4 Greys, Mildly ported head, Ahmed spec inlet cam, Port matched inlet, Forged pistons, RS500 style cooler, Alloy rad, Mapped by Ahmed on L8. Should be good for over 400bhp, 420bhp if i am lucky on a proper set of rollers.

nice, for now my spec will be fairly simple as i want to get some use out of her and not go mad on spending but i can see me building a tasty engine later on which will no doubt suit the T4 better.

Tbh my engine spec isnt really suited to a T4, a T38 would have been a better choice. The price i got my T4 for i couldnt turn it down. I am happy with it though. Talking to some people with T38's and GT30's mines on boost around the same as them if not before. I dont know if this is donw to bad specing od parts etc though.

I am not really that bothered about any more power for now. I just want to get the suspension sorted and set up with a few more add ons still to come.

I got the T4 for free off of my mum so thats why i`m using it :banana:

for now i only really wanted a solid 330 bhp as to me suspension and brakes are more important, i do have the suspension setup almost ready to go on the car so im half way there :cry:

the thing is there is always something else to buy........it never stops lol

Just run it on greys if you already have them and get chip off one of the tunners[Depends on who you prefer] to suit it. The car will do way over 330bhp mate with Greys and a T4. The other option is to keep the T4 and use a T34 to get your 330bhp. I still would still use the greys over the green at this spec though.

I have the brakes and Suspension is pretty good now. I have a few other bits in mind to make it alot better though, the trouble is i want a house more than i want those gucci bits so it will have to wait.

yeah i supose i just as well go full on run greys ect or may find out about these Siemens injectors mate.

i have a few things to sort before i`m sorted here but i`ll probably have a word with stu@MSD and go from there :top:

You wont go far wrong with Stu mate :top: Just tell him what you have and tell him your not bothered about power, just want it safe for track etc.

How cools your mum? Mine gives me free socks occasionaly, I had to buy my T4 my self though :cry:

Phone MSD, they'll see you right chap...impeccable service on all counts imo :top: :banana: :top: :banana:

The size of the turbo is a bit too large for the fuel you can run from the injectors.
The point is why have lots of lag with a T4 if you don't need to, get the same power on greens with a T34, which despite some bollocks spoken here will run to around 375/380, the last I saw was a T34, machined out T3 comp housing with a .48 housing and it made 377, on an engine dyno, repeatedly all day long forever.
It had in excess of 30 power runs, turbo was maxed out but coping no problem.
Anyone who thinks thier car with a T4 and 18 PSI is going to eat a stage three cossie on 25/27 is most likely on drugs.
The engine is merely an overglorified AIR PUMP, air = OXYGEN = POWER, all else being equal ie capacity, more air = more power simple as.
T4 are unbeleivable laggy, not good at all for a race car, where torque spread is the name of the game, yes they are faster when you get going, but by the time you get going the T34 car is gone away and finished the race.
Greens are capable of in excess of 600 BHP, but not with the ford ecu, it is antiquated, but does the job, bit like solid tyres rather than air filled ones!!
Consider a aftermarket ecu, and go batch fired as it would be even better at higher rpm.

I run greens & T34.63 on a chip that I was told was for 380bhp with greens.

So yes, you do hear different things wherever you go. :banana:

tabetha Having seen both Churchys and Daz's car ran at APT both made around 330bhp and the injectors were maxed. So i am not talking bollocks, a car on an engine dyno will allways show more power than if it was on a rolling road as you have added restrictions.

Churchy and the others have seen what my car did at 18psi so again i am not spouting shit. If you want ask Stu how quick my car was at 18psi he will tell you straight.

Tabetha... T4's arnt good for a race car? oh i see now where the Rs500 went wrong :cry: they were crap wernt they didnt win a thing :cry:


anyway....

a mate in our group has a T4 powered escort, and nobody can get anywhere near him :cry: if it starts to drop boost, all he does is CHANGE DOWN, then he has more air flow than all the rest of our group put together :cry: its all about jkeeping the turbo in its boost parameter ,and its not all that hard on track....


to me, the difference is where the turbos make there peak power, the t34.48 makes it quite low ,which doesnt give great bhp readings, even purely swapping the ex housing toa .63 will push the peak power up the revs a bit can increase by 30-40-50bhp.

the T4 wont make its peak power till much much later, which does give good bhp readings, much more than a t34 could hope for anyway... the air flow from a T4 is immense, and a t4 holding 18 to the limiter would see a good power figure, by the limiter the t34 would have done its work and gone to bed and you would see a t4 powered car whistling past :roll: and thats just in first gear :cry:


nashes car went very very well at donnington a year ago ,on track could keep with almost anything, even a t38 powered car at 30psi iirc nash?

wonder what the tuners view on this is... hang on i'll post up.

Yes Jase thats right mate. I could just hang onto richies 400bhp T38 car down the straights, that was on my old engine that was massivly over fueling and running 18psi.

have a look at dingys post in GD, he is thinking about down grading from a T4, cus on track its just too fast. T4's are awsome.

and my suggestion would be to run at least greys

My 38 comes in around 3.7-3.8 and pulls all the way to the limiter

Mark is going to be peaking it at 35-36 psi holding 29 so should be around 450-460 he hopes for, i'll let you know after it's ROLLING ROAD session. :top:

:cool: :cool: :cool: :cool:

id have to agree, if i keep my car between 6 - 8 k it is bloody scary fast, if you dont mind thrashing your engine to the top revs a t4 car will destroy a t34 everytime. ive had both twice at all different specs t4 is the king imo :top: :cool:

cheers for all your info ect guys but i will be running a T4 turbo 100% its just the rest of the spec i`m going to reconsider :cry:

i`m not affraid of giving the motor some shit as if it blows i`ll build another one :cool:

a dont find the lag from a low comp t4 engine any worse than a t34 escort

Ive got some light blues for her now and stu is happy to work his magic and sort me out a chip so happy days :top: :banana: :cool:

just dont know what boost to run now :cry: :cry: :cry:

Stu will tell you whots best for the spec of the chip he will suply you ;)

yeah i`m sure he will mate i just forgot to ask :cry:

i asked about a chip over 7months ago but still not got arond to gettimg it sorted :oops: :cry:

lol i will sort mine out in the next couple of weeks as i need this car running right for a track day in november :cry:
