Whats the best injectors for about 380bhp cossie motor.

I am a bit new to all this so any help is much appriciated.

 

Id go with 55lb siemens mate but of course will need to be mapped for this..
If you need any info or mapping give me a pm


cheers danny

 

Yep, DITO what Danny says, 55s all the way...

 

Cheers danny, i believe you have either done or are going to do my mate adams escos.

Either way was gonna contact you before anyone else anyway.

Cheers pete aswell.

I thought they were going to be the ones anyway i just was not to sure.

 

If buying new I'd go for siemens, but if you had a set of greys for example they would be fine too.

light blues,greys or siemens....question is...are u staying at "380" or will u up the power

 

To be honest pete i have never owned a car with more than 200bhp. I have driven loads with alot more than that as i used to work for a jap car importer.

I would like to say i will stay 380 for a while.

 

I'm running 55's in mine at around 400bhp...

However as pete says, if you are going to up the power any time soon then a set of siemens 83lb might be better as they give you scope for more power in the future

 

Hi ya pete yes weve done adams mate and it made 390 hp with just over 400 lb ft!!!very nice..
As tabs says if your going to buy new then siemens are best but if you have a set of light blues or greys they would do the job..siemens are far better imo..

Speak soon mate.


cheers danny

 

So how much power will the Siemens 3102 (55's) be able to handle safe ?

 

as above would these be suited with a t38 or the 83 lbs ?

 

The 55lbers will do circa 450 hp ,if you want more power like gt30 or t4 etc you will need 83 lbers..

cheers danny

 

Sounds like i better get in touch with him so he can take me out for a spin then.

 

My car maxed out at around 450 on greys if that is any help?

 

surly its worth speaking to who evers going to map your car fella see what they prefer to use!!!

but persoally from what ive see n read i would go for Siemens 55

 

Im changing to 83's after fitting my r/b t38,getting a live map on air injectors.

 

55lb at 435 are flat out
greys 450 or very close
and blues tops of 400

i would go for blues for 380bhp

we do so many blues/t34 conversions and they go very well

 

....not a major dig....but u always seem to differ from what other people/tuners say because of ur dads dyno........but i do agree with 400's for his requirements........lovely spray pattern

 

i say what i see with my own eyes, the dyno which we use is on par with every other major dyno in the country and is spot on !

i may be wrong but we were doing a engine on a t38 set up and we tried some 55lb siemens

now i may be wrong but im 90% it was 55lb's and it was around the 435 mark !

what is wrong with the blues though ?

around 400

 

light blues.........i had a convo with two of the big tuners in the country about my car on light blues making 427 and they said yeh if everything was "spot on" it could........on the other hand my tuner laughs at this.......opinions vary lol

 

your tuner is ahmed right ?

 

......shh ting.....

 

and just how many engines has ahmed mapped on blues

id take ahmeds and mya proper dyno's word over a rolling road print out

 

so what sort of power would i expect from the 83lbs & t38 ?

 

dependant on engine spec but around 440/450 mark is usual for a t38 set up with a reasonable amount of boost

 

....including mine..............no but when i say its bollacks and knock 30bhp off at a R/R day other people get upset....

 

sounds about right although im on greys at the moment may swap to siemens with the new engine

 

....what t38 aswell.......i'm on a ut t38

 

same as you mate made 412 on ut t38, greys & 28 psi

 

I love my t38,cant wait till its fully mapped.

 

Msd ?

 

is it standard engine then ?

our engines with head work, cams and ut t38 greys at 26psi held (6500/7000rpm) make 440/450

 

mines 7.5.1, std head n cams ut t38 hits 30psi holds 28 and tails to about 27psi top revs.......427/390..........(if u belive a r/r)

 

It will be m8,i bought joe's t38 btw.

Sorted jim,iv'e got one of your old mans engines and was gonna run my t38 at 2 bar.

 

never knew you was on t38 !

will deffinately be 450hp then

 

Your old man did say that figure too jim,would you add an inlet cam into the mix as mine are standard ?

 

[quote=J1mbo;5045201]never knew you was on t38 ! .......yeh but still on light blues....was ment to be a t34.63/400bhp set up but then a ut t38 came up for sale

 

yes you want a inlet cam in there, a bd14 on inlet would do nicely

it has valve cut outs in pistons right ?

 

dont you fancy greys and inlet cam give it a bit more up top ?

 

......i've asked about a cam n greys.......he didn't seem to think it was worth it on a std head
