what would you say is a safe amount of boost for my saff? its running 200block,t34,multilayer head gasket,uprated pump,803s, alcon 6paddle,only a 4x4 intercooler tho. its currently set at 21psi does this sound about right as dont want rear diff or box to get mangled!!!

 

Asuming its a 2wd the diff and box will be fine at that power level!
I wouldn't advise running anymore boost until you get a decent intercooler though and then about 24/25 will be fine

 

sorry ,yes it is a 2wd ,so 21 is ok for tho mo? next upgrade will be 500 cooler

 

The box can handle a lot more than the 300 ish you are currently running and the diff also as long as your not a traffic light racer

 

Sound just about right at the moment, and as Spadge correctly states, next thing on your list is a bigger intercooler, and then you can add a bit more boost. Up to about 25psi. But take the advice of some of the Real Tuners...... Karl Norris, Stu (Motorsport Developements) Mark Shead (MAD Developements) etc.

BUT : Remember that it's just not a matter of turning up the boost, without adding extra fuel at the same time. GET IT MAPPED PROPERLY, OTHERWISE YOU'LL PROBABLY MELT SOMETHING, ALL ENDING IN

 

i just want to be on the safe side really, had it dynod at pts luton it got 347bhp at 21psi which is good going aint it

 

good....but a little optimistic

 

347 @ 21psi on std cooler?

 

its a saph... run as much boost as it takes to blow the fucker to smithereens!

 

sorry but

 

14k plus posts dave most of them pointless lol,what boost should it be running on a standard 4x4 intercooler then ? any ideas?

 

Don't take any notice of Dave, he's just go no class that's all.

347bhp from that spec, using those injectors can't be correct. You'd have ran out of the fuel capability of the injectors long before 347bhp. Not wanting to make you feel bad, but I would be about 99.0% correct if I said that those rollers ain't reading correctly.

To make a given bhp, with a given spec, it's not hard to work out how much air and fuel the engine needs to consume to produce a given bhp. And to produce 350bhp, your engine would need to consume more fuel than your injectors are capable of producing, so it's not hard to work out that your spec is not capable of producing a true 350bhp.

With the spec you suggest, and the boost your using, I would expect you to produce between 320 - 330 bhp. and would not run more than a constant boost pressure of 25psi (absolute max). But don't just go and wind on the actuator arm to produce more boost, without first getting someone to check that the car is mapped with the correct fuelling. Some people think that because they are using certain injectors that have the capability to produce ???.... That they can just wind up the boost....WRONG. The injectors will only produce what the ecu map tells them too, and if the map isn't set up with that in mind, then it will all end in

As for DAVECOS : Bring it on baby, my Sapphire will kick your arse big style.
