treadstone manifold for going single

[davep]

Hi

im just wondering if anyone has fitted a treadstone manifold and what there is there opinion

and what issues they had with them if any and im guessing there is a clash. im guessing there is a clash due to being LHD and not RHD

 

please see web page

Have a look here at my project page, my single install is based around a Treadstone manifold:

Here's a few links to get to the parts with the manifold in....save you trawling through it all

 

Wastegate Area and more Wastegate Stuff

 

Crack Testing

 

General Porting and more Porting

 

Gasket Matching

 

General "Kit" Stuff and Here

Thanks dan

i got to admit i was hoping that there might of already been some pre bent pipes to save manufacturing them lol

great thread alot of things to think about

If you're just using the manifold I wouldn't have thought there'd be a problem on a RHD Supra, if it came with a downpipe designed for a LHD you may have problems; the issue on a RHD car is usually with the downpipe &/or IC pipe hitting the steering column/rack. If they don't do a RHD downpipe you would need to get a custom one fabricated. Do they supply IC pipes to be used with the manifold? If not you'd also need to fabricate one of these.

 

The wastegate opening in the manifold looks very small, it'll probably need machining bigger. What turbo are you intending to use and what is you power goal? It says 'for turbos supporting up to 1000hp' take that with a huge pinch of salt, the wastegate opening for a start would never be big enough for a turbo that could make that power - doesn't look big enough for even half that - 600hp+ would probably be okay on the manifold if the wastegate opening is machined, more than that and you'd be better with a tubular manifold

There's room for that wastegate port to go out to well over 40mm diameter Nic - that's bigger (and not to mention a shorter route and much nicer routing angle) than the majority of tubular manifolds on the market. I do agree it's crap in the "off the shelf" state though

That's a fantasitc post earlier Dan, very useful, might have to steel that for the Tech Discussions area if you don't mind?

i would like about 600 - 700 i was thinking a garret t04

i am intrested in the cast manifold as i have been explained that the tubular manifolds are prone to cracking and for the power levels im after there more than enough

No problem mate, which one do you mean though?

That's a lot of power especially if you're aiming more to the 700 area. You sure you want that much?

If you're edging above the 600bhp level you're going to struggle with a cast manifold, a premium tubular is more suitable once you start thinking of 650bhp+ unless you plan on using exotic fuels, meth, etc.

 

How did you arrive at 600-700bhp as your target? Have you ever driven a 500bhp or above supra? Are you aims outright bhp or wide torque area? What is the car to be used for - road, track or drag? All are critical to make the right manifold and turbo selection for your planned use of the car.

That looks much better Should have read the links before posting

i have not drove a supra but i have drove an RS4 at 650 bhp so thats why to 600-700 was my target as i enjoyed it and the car is for part track and road
