Assume you have replaced the intake pipe?

Also it's a 20yr old car, what exactly are you expecting, the same BHP and torque it came with out of the factory? Get it on a dyno and see what its producing and go from there.

ttutbo79

Yes it has walbro 255 fuel pump
440 sti yellow injectors
Decat
Boost controller
Could the split air intake hose causes loss of power as maf thinks its sucking in less air than it is causing it to under fuel

wtf, seriously?

ttutbo79

Well what effect would it have on the engine have if its pulling in more air than the maf thinks it is

beardo47

Would be running lean, more air, less fuel = lean.

ttutbo79

and would running lean affect the performace of the engine eg less power / cutting out / long for turbo to spool up

Less bang, less gases spooling turbo, more heat...engine goes pop very quickly

get the pipe sorted pal..it may not be the problem but it 100% wont be helping the running\performance of the car

Get a viper intake pipe, good quality and very easy to fit

The MAF is probably screwed as well.

so you have a spit intake pipe and wondering why its not running right?? thats the least of your worries as that will be running lean as hell and will end up with a nice hole in a piston.

id be getting a new intake pipe before running it again.

ttutbo79

New pipe ordered

What one did you order ?????????

ttutbo79

The same one that was on it

Is it a slandered hard plastic one as you will probably have to remove the manifold to fit it, a silicone one would have been better.

ttutbo79

Why would i have to remove the manifold to fit air intake pipe it goes on to the top of the turbo

bmw730i

Mines a front entry td04 and the pipe runs under the manifold.

ttutbo79

Not mine and mine is td05

You need to get it mapped after you after fixed the intake as it will be rich with non standard injectors, fuel pump, decat , etc.
