I appreciate not really FI related. But the guys here make a lot more power, so would be better placed for advice.

I would do stepped 1 3/4 to 1 7/8 if you can. 2" would be tight in the plug area.

Unfortunately, nobody in the UK can bend 1 7/8" tubing....

I want to be racing again early-mid march, so sending mine to the US to have a set duplicated, isnt really feasable, as it will definately take far too long.

Its either stick with my current 1 3/4" which are fine really.

Get a new set of stainless 1 3/4", which is probably pointless

Or the 2" stainless.

Plug access isnt something I considered though.....must check that at present, although I know its pretty easy for me now, but a couple of my leads are fairly close.

you should just use 1 3/4.........people make alot more power then you will using smaller 1 5/8.

They do ? I dont think ive seen any LT headers around 1 5/8" except direct replacement shorty style, for otherwise stock engines ??

The most common is 1 3/4" or 1 7/8" for those making a little more power.

can you shed any light on these cars making decent power on 1 5/8" ?

I've seen some turbo mustangs dip down into the 8's with 1 5/8 headers.

turbo headers are NOT the same as those used for a supercharged, normal style exhaust application.

despite the name, my car is not turbocharged, it is supercharged.

What the hell kind of car do you drive? lol

stevieturbo

Im in the UK, its a 1980 Ford Granada ( obviously not the same as US car with same name )

382 LS1, Edelbrock 215 heads, 224/230 cam, with a Vortech V7 YSi blower, time in sig etc.

So I'd guess Im making a little power. Maybe 800+rwhp or so ? Dont know for sure.
