max bhp standard manifold?

[EricYellow]

What is the max bhp you can get with a standard exhaust manifold?

 

[watoga]

I think you can get reasonable HP figures using the standard manifold. Perhaps even up to 400 BHP?

Someone will correct me if I'm wrong though.

I've had 460.

 

[EricYellow]

@Ed, could it be your PM box is full?

 

[markwashington]

A ported standard manifold is good for 450+, search "ported standard manifold" to find out how to do it.

Yes, it looks like Ed's subsciption has run-out so his inbox is over-filled.

Whilst I would love to pressure Ed to pay his renewal, I think it's only fair to mention that you can contact him through the Fusion Motorsports website.

I don't think its the manifold pre-say thats the limit, more the size of the turbo you can fit onto a T25/28 flange

i don't think there is a direct answer to your question. the manifold is great in design (comapred to other OE makes) and can make good power, but in my opinion, if your car is doing 450 with a standard manifold, i am sure you will get more with just replacing the manifold.

The standard manifold is fantasti if ported (obviously). Mine was running 395bhp with loads more to give.

I keep meaning to pull mine off and have a go, but there are too many horror stories of snapped exhaust studs etc, so I've just not been game yet. - A bigger elbow is probably a higher priority for me.

you want a Manifold Like this

 

[PobodY]

Nah, that's all back-to-front...

A Reversed Turbo Kit is not even a Bad Idea plus you can make a nice Elbow

 

[Makaveli_se7en]

Just need to swap the water pump and steering pump for electric ones and then rear mount the alternator. Then you can have plenty of room for a nice intake and elbow

 

[PobodY]

...or you can fit it where there's already space.

 

[Makaveli_se7en]

well I was thinking more along the lines of then move the front cross member forward 3" (as The bear did with his car) and then you'd have room for a compound charge twin turbo set up. Lag free 750bhp anyone?

But then I think its fair to say I don't think like normal people :loco:

 

[Spikey]

is the front cross bar needed?

 

[Makaveli_se7en]

Without it you'd loose a lot of torsional rigidity from the front end

So its not just to hold the mount?

hope your going to move the alternator other wise all the nice work that has gone into that will be wasted by the awkward path to the turbos inlet.
