ok, want the magical 200bhp at wheels figure, but roughly wot spec and boost levels r needed?

erst running mfi management

parts acquired for new engine so far:

stage 2 hybrid t3 turbo
-31 collins actuator
turbo systems ecu
piper 285t2 full cam kit fitted to standard cylinder head
radtec fmic
cosworth fuel pump
rebored block with standard rst compression mahle +.29 pistons
standard rods
reground crank
heavy duty bearing kit
grp A gasket kit
uprated oil pump
mongoose 2.5" system
pipercross induction kit

thats my existing spec for the new engine build, but would rather make changes now before assembly if im going to fall short of the figure i want

any ballpark figures wot power that spec could make, and what changes u would make??? any advice appreciated

 

i would fit a Std head gasket,


if your gonna stick with the mfi, then a 5th injector kit, and a full set up.

and with 23psi, you should get your wanted bhp+.

 

is head work a good route to go down?? or wil i not see the noticeable increase i wud want for the cash outlay necessary? my cylinder head already been built up so would mean a complete strip down again

also, standard rods and pistons?? need uprating? or at least maybe lower the compression by machingin the pistons? iv never really been given a difinitive answer to this

in terms of 5th injectors, are these stil a bit primitive or is it the only option with mfi to get the right fuelling?

 

Head work will help, but not 100% needed.


Std rod's and pistons will be ok, but do need ARP bolts

 

cheers mate

any contacts for 5th injectors and maybe some headwork?? struggling to find a 5th injector supplier

 

Would it not be worthwhile considering moving over to efi ?

 

i think efi wil involve a little more time and money than is feasible for me right now, im close to my limits on funds as it is if im honest

 

Erl 5th injector.


Demon tweeks if new, or try in the RST parts frosale section.

 

Of all the RST's I've seen ran up on the rollers which have made 200@wheels.
The cars fitted with the 5th injector set up have performed less effectivly that those with KE fuel mod.

The common denominator of the cars which have made the power appears to be.
Lower compression than standard, a big valve head & more aggressive cam and minimum stage3 T3, a large capacity IC too.

 

what exactly does the KE fuel mod entail then? and where to go and roughly how much?

 

Only thinkgs i would change would be the compression ratio and the cone filter.

Yes a standard headgasket would also be a good option.

If the car is propery set uo you wont need anywhere near 23psi to make the power you want, im making more than you want with a lot les boost.

 

Forgot about yours David, yours being the exception to what i've previously stated above.

 

from memory u run a standard air box i think? but also a posh tubular manifold which im guessin gets u a few more bhp

wot sort of compression ratio shud i be looking at then?? and is there any risk of weakening the piston in machining it?

 

But isn't yours is running Stg 3 head, mani and other mod's

 

And a new strenghened GEARBOX.When mine was tuned to 220 b.h.p,the gearbox decided to shit itself. Oh and a 4 paddle clutch.

 

7.8:1, and skimming pistons is fine.

 

gearbox and clutch already planned out so hopefully not an issue

 

Comparing mine to yours

stage 2 hybrid t3 turbo - T28 turbo
-31 collins actuator - -34
turbo systems ecu - AVA ecu
piper 285t2 full cam kit - Newman solid lifter cam kit + vernier
standard cylinder head - Stage 2 big valve head
radtec fmic - AVA custom intercooler
cosworth fuel pump - standard
rebored block with standard rst compression mahle +.29 pistons - wirerungblock overbored .25mm
standard rods - same but with ARP bolts
reground crank - same
heavy duty bearing kit - same
grp A gasket kit - Standard Ford
uprated oil pump - high pressure
mongoose 2.5" system - Magnex also with a tubular manifold
pipercross induction kit - standard airbox and filter

I also have a

Paddle clutch
2 Fuel mods
7.5:1 Mahle pistons

Think thats about it

 

If you have'nt already then id suggest you consider having your rods shot peened which will add to their strength.

 

what are these 'fuel mods' i keep hearing mentioned?? big secret? lol

 

quite possibly, depending who you speak to

 

Call

0141 848 5257

And ask about them

 

shit why cant i live nearer scotland

that ava fuel mod sounds exactly what i need

Karl Norris does it to I believe..

 

Well, IMO you certainly won't do it on the Stage 2 turbo. We have seen around 180@Wheels on a Stage 2, but that was a properly mapped EFi engine.

I don't actually think you will do it with a Stage 3 either, not on MFi anyway. Worth a go, but I wouldn't be surprised if it didn't make it.

Oh the amount of '240bhp' RST's we have seen lately. I haven't seen one of them make over 180bhp yet.

I think to make 200@Wheels a certainty, you will need something like a T34, but I would be concerned about the rods, in terms of the power that turbo could make.

Then theres the cam. 285T2 is an OK'ish profile, but don't expect it to last very long.

 

dont know if you will make it with your spec, but it can be achieved with a stage 3 hybrid turbo as long as you change the exhaust housing

 

JamboRST's making 217 ATW with a T3

 

ive recently had dta fitted to my series 2, on monday it made 187bhp with 230pounds ov torque @20psi

1620 low comp
fully lightned & ballanced
stage1 t3
radtec front mount
stage3 specialised engines head with kent cvh35 cam and vernier
arp bolts snd studs throughout

thought it was gonna make alot more
jus bought a t34 so i can crank the boost up

 

ok, so ive spent today sorting out having my pistons machined to lower the compression, rods shot peaned, and ordered arp rod bolts, and hopefully got a genuine ford headgasket coming too

if i was to get 1 of these 'fuel mods' sorted to help the fuelling, wot sort of rough estimate would u giv for bhp@wheels and also bhp@ fly??

kind of feel a bit shot down after reading the last few posts, iv got no chance lol

 

You will definatly need headwork of some sort, IMO.

 

I thought jambo had a T34, or have I been imagining things again ?

 

 

doh!

I was thinking of the post when you posted pics of yours and jambo's car power at certain revs, just thought I read there that it was a t34.

 

Ok, cylinder head coming apart, i want some headwork to get closer to the magical 200bhp@wheels figure

so...

whats the best spec head to go for, how much am i looking at, and wheres the best place to send the head?

also, ecu, my turbosystems 1 is limited to 18psi apparently, so what ecu should i be looking to run? whats been proven to give consistently good results as i hear bad things about several different brands

 

It wont come cheap - take a look at T28's spec, he's got 205@wheels which is pretty much what your after.

 

Not at the moment, wonder if there is problems

Jambo 197 ATW
