Right chaps need a bit of help am currently running 15 psi with the following mods on my series 2, piper cam & pulley, stage 3 turbo, stage 2 gasflowed & ported head, grs front mount with twin 9" spal fans, turbosystem's chip, k&n, magnex exhaust and bailey breather. Rebuilt not long ago with oversized pistons etc, question is i want woodford garage to turn the boost up am i right in saying 20 psi would be ok?? everything has been checked and all is in good order, any help would be much appreciated.

 

you could run 20psi if fuelling is ok, yes.

 

Thanks rick i was thinking 18-20 but wasn't sure, if the metering unit is good and can fuel enough for 20 psi could it be turned up more or is that about the limit?

 

Its not really something a forum can tell you mate. Once your tuner has it on the dyno all will become clear, as long as your metering unit can supply enough fuel and you don't run into det 20psi or there abouts doesn't sound unreasonable.

Rob,

 

the turbo can run 25psi plus, but you need the fuel and ideally some uprated rods to take it.

 

Ok thanks rick, rob all i wanted was a rough estimate m8 and dont want to run anymore than 18-20 anyway and the metering unit was a fully reconditioned uniit 3 years ago so 10 psi low boost and 20 psi high boost it is all being well thanks rick and rob

 

apprantly stg3 hybrid can boost to 27-28psi feuling is issue

im running 5th inj for more fuel, stg1 15psi stg2 20psi

hopefully turning stg2 to 23-4 psi

some say you'll need steel rods go over 240-250 bhp

 

I dont want that much lol 210-220bhp is plenty for me

 

20psi should be enough to reach that figure

 

a mate of mine has near your spec and runs 20psi on a t3! its bloody quickk!! only better thing u have is ported head etc

 

what about pistons !



yes 20psi will be sound , who is settin it up for u, woodford does not have rollers does it ?

Ben


put up a pick of ya car mate so i know who it is when i see ya

what pistons n rods are u running ?

headgasket ?

 

20psi will kill the engine if not set up

put it to 14psi max till you get it set up

 

It is being set up thanks and i already know it will kill the engine it has been set up for 15psi at the moment, and ben still dont know how to put pics up lol james is doing it at woodford and testing it same way jano does out on the road, engine was rebuilt 3 years ago running oversized pistons and i think they are standard rods and its a standard ford head gasket, the history and resto photo's of the car is unbelieveable it had a 4 page spread in rs owners club mag in 2008 you may have seen it in torquay and my other white one is also still in torquay lol will have to meet up m8???

 

get a wideband lambda gauge off ebay for 160 quid, then you can "set it up"

 

Wish i had the money at the moment m8, you still got your silver pulsar???

 

lol, na sold it 18 months ago, ive had a 205, the sierra and a wrx since then mate

 

Shame that was a tidy one too they are becoming rare now as well, what you driving now m8?

 

a polo tdi and my 2002 WRX scoob, loving the scoob, nothing wild 270bhp

 

Chaffe - U must be due another ford soon?

 

oh dear, my welder is busy making other things just now, it doesnt want to see another rusty ford!

 

Standard pistons will do over 300 bhp.

Rob,

 

Rob- thats good to know. Esp when alot of ppl are keen to change pistons as their 1st engine mod!

Chaffe - i understand your point, but surely a datsun rots just as badly?

 

No worries Roger, there are lots of people using standard pistons, but the rods are a well known weakness of the cvh.

Rob,

 

My old S2 was running 215bhp (flywheel) at 20psi set up at Harvey gibbs it had bayhoo chip scorpion exhaust and proalloy intercooler everything else was standard and I never had any problems over the 4 years it was like that.

 

probably thats why i have a 9 year old subaru instead

 

fuck that , i had one snap on me with 200bhp


who in there right mind would build an engine 300+ bhp and use standard rods !

 

Mines maxxed out at 17-18psi as it can be heared detting so i aint turning mine up, efi for me next mod,also im on same mods as you other than headwork,good luck with it mate.

 

No one! Rob said standard pistons will do 300bhp.... Which they will with a decent set of rods lol

 

my bad , miss read the post



Ill start again then , whey would u risk standard pistons with over 300bhp, and why go through the trouble of maching the pistons to take an aftermarket rod , dont understand

 

You wouldnt, but it saves £300-£400 pounds and if you want sub 300bhp but more than say 240bhp then maybe you would just change the rods.
I didnt, but some might... It's quite a saving.

 

Chaffe, i bet the scooby is still a hoot to hoon around in...? Is it on MS?

Daniel, thats good to know that 200+bhp can be had reliably!

 

Lol,

Nothing wrong with standard pistons, nms rods (i think they are fardon) are floating pin so you don't need to have the pistons machined.... like me.

BUT if you are overboring you will need new pistons any way, and at £350 you may as well spend the extra and get forged pistons i agree.

Rob,

 

Mine made 202 @ 18psi on standard turbo and internals, Tony Turbo's big end bolts didn't like "H" and 22psi on the way to 10 of the best
