Anyone used the Williams www.turbostreetfighter.com exhaust manifold before, its priced very well. I'm just wondering about the quality.

Marcus is the owner of that shop. Even though he has only been in the world of rotaries a few years, his mechanical skills are very impressive. He grew up in his fathers industrial machine shop and can use all the modern machines.

Last year he personally supervised and built some of the special tool boxes used on the space shuttle. These hold the tools used to build the space station. There are a marvel to see!

He use to run the fastest ?class? Honda a few years back, and he is a part owner of a very fast Trans Am in NE USA.

He does tend to think outside the box compared to most people.

Is there a shop number where I can get a hold of Them????

I will give it out only if you send me a private e-mail.

Its kinda weird that some of his pricing says "call" yet there is no phone number listed on the site. I wonder if he realizes that his "contact" link shows NO contact info on it????

If you call you might want to mention that to him just in case he's not aware of it

BTW - I cant wait to see what his dragster is going to do!!!!!

I was thinking the same thing.


Its a nice manifold, there is room for improvement. Like personally I think the turbo sits too high too far up, its very close to the hood with a T04e, and dont bother if you are running a stock mounted intercooler cause then you will have to get a new intercooler pipe made up from the turbo to intercooler like the one pictured and you will have to get your end tanks modified to work with it. Other than that I think the manifold and wastegate setup he offers is a good buy and marcus is a cool cat so......

Damn Greg! That is a sweet ride!

Here is another pic of the manifold if anyone is interested...

I would have to agree with Greg here. The setup was not made for a SMIC. What I do like about the manifold is that is keeps the turbine away from the LIM. I've seen the HKS cast manifold and it scares me how close the turbine is to the LIM.

Looks like the wastegate only vents one rotor... Blitz does that to, in fact that looks like a copy of the blitz manifold, not sure if it would work that good..Max

Is'nt that Josh Stanley's car?

This manifold is not fully divided so it is not that big of a deal to only vent one side. I really doubt this is a copy of the blitz, but then again I have never seen the blitz. Do you have a pic of the Blitz manifold on hand?

Maxthe7man

I am not certain, but only venting one rotor could give you boost creep issues, depending on what size a/r and what size of wastegate one is using, I would think venting both would be much more predictable..
I finished a manifold recently that vented both rotors, and tying the two rotors together was alot more work, jjust about twice as much(go figure).. I have to build another manifold for a friend of mine, I am thinking on that one of just trying one tube, but it may be a mistake..
The blitz manifold is on the japan blitz website., its of similar configuration however it has alot less welds and joins in it..
I think the point at which the wastegate ties into the downpipe should be alot farther back as well.Max

thanx for the praise fellas! now i will try and answer some of your questions about my setup: first off the wg does not only bleed off of one rotor it is placed in the same chamber where both of them meet it is not a divided manifold, if it were than it would creep.

it is not a copy of the blitz header it is my own creature.

you can run any size compressore housing you want i have had T76's on the same header with no clearance issues, my reason for the place ment is to get a longer primary header length and allow for the 4" DP.

as far as the website goes i did not realize the phone number thing but the reason is that i do all of my business via the internet so i dont even have a land line anymore. contact me through my website or wwm1@wt.net

it does not matter where the WG ties back in to the DP so why go through the hassle of moving it? it does not interfere with anything and you will not gain any hp by doing so

my system is designed to be used with a front mount(especially mine) setup as i do not believe in SMIC's for street war, the work great while you are moving but if you are going light to light they suck, IMHO!

sorry for the delay in getting to this but the FUN ford event is this weekend and i have been busy getting a 7 and an 8 second stang lined out for the weekend! one of them just ran a 8.22 this morning on 10.5's the 7 second one is have traction issues but still running in the 180's!!! let ya know the results tomorrow night after the finals!

Maxthe7man

Just a fluke that it looks like the Blitz I guess then?
Looks like an overall good design, is it mild steel?
The other thing is the wastegate exit and integration, part of the reason for putting some distance on the wastegate piping is to allow for expansion and contraction as the wastegate inlet and outlet don't always see flow, a couple of swing joints with elbows helps to absorb thermal expansion and shock, with the close coupling like that, you can expect that saddled joint into downpipe to break and leak at some point.
In the corky bell book he talks about moving the wastegate outlet to an area of less pressure away from the turbine area as well, his thoughts are about 18" away or more, however its only his theory on this, but is also part of the reason internal wastegates suck as well..Max

turbostreetfighter

if you notice my DP expands from 2.75" to 4" in about 5.75" this creates less pressure in the area that i tie into . i have played with different setups and gained nothing by moving it. book world and real world are always two different things, i tend to act upon the real world and my experience in turbo systems. i am the type of guy that tries many setups to come up with what i believe is the best alternative. i have been building this EXACT setup for three years now and not one has Cracked. there is no way that it will crack under ANY cirumstances ( as long as you keep your tires on the ground!!!!) you would have to so some crazy **** to bust one up.

either the WG is open or closed, when it is closed there is no flow so it does not matter what the piping does. when it is open you have pressure on boths sides( DP and header) with more pressure being on the WG side. and as you know higher pressure wins. i have no proof but it may even draw some sort of vacuum as the exhaust flows over the WG inlet, i put a slight angle on the exit pipe.

I always thought it was better to run a divided manifold for rotary engines. What is the benefit of running a divided vs an un-divided manifold. the turbo i have has a divided manifold. do you sell divided manifolds also and do you make an adapter plate to run a hks standard wastegate?
