    From memory there was a fellow on the SC forums years ago that used a Redline single with a plenum made up to sit on the carb flange and front mounted V6 throttle bodies.

    COME TTB hasn't been completely ruled out, its definitely one of the easier options, they look good but i always thought their performance wasn't quite there compared to alternatives? if i can go the single plain route with single throttle on an elbow and get better performance for less outlay it would be an obvious choice.
    another option is to fabricate a plenum on the single plain if its beneficial.

    i know scott 355 (spasm) ran a plenum with single throttle on the hiwinder intake with his gt4088 355 setup (which i actually bought off him many years ago and never used) but then switched to come ttb. i cant quite remember the comparison but recall him saying it resulted in slightly slower in et's with a higher mph?

    i think Az with the 9 sec vl calais ended up running something similar with the redline as well.

    The VL was a sneaky bit of gear but yeah, pretty sure it had a redline as well.

    Really depends on how much bonnet clearance you need/want.

    az only made 20oddHP when he changed from the bananas to the redline.

    A mate of mine who had a pretty serious 355/v7 running 18psi. Was in a VH running 9's back in the day. mid11's would know him. Names Claydo.

    He said his combo had better response with the 4bbl and velocity elbow then it did with the elbow and single TB. He now has a Walky TTB on and he says the old dual plane combo was much better.

    I'm doing something similar with this setup. low mount turbo under the front for maximum stealth factor(hence not wanting to cut the bonnet). The 42r is a decent sized unit though so going to be little tricky fitting it under there. I'm confident though.

    Thats in a phoenix red vn ss now? Im surprised the twin throttle wasnt as good with response. Did he make more power through the mid-top range with the walky mani? I'm dead set on a vn grp a eventually. But the money can be better utilized on other stuff at this point in the build.
    Az's 20hp gain going from bananas to the fairly average redline manifold is probably a decent improvement considering. I'd expect a little better gain with the come single and maybe more again with a tp/harrop. I guess thats the good thing about boosted combos, the intake wont make as big of a difference compared to if it was an N/A combo.

    Does anyone think there's a disadvantage to using a fabricated elbow over a cast one like the ones in the links?

    I think the ttb come manifold will work better as tunnel ram type setup with efi air flow feeding from one end it is going to be compromised in its distribution to the cylinders plus the short runners will make a better peak hp number but a not so great low end power.

    I think that because the 4bbl single plane type manifolds have 2 lengths of runners which will lend to a broader type of power and a better distribution rather then favoring one end .

    Crazy money for the walky manifolds another option is the TSP Manifold : Trick Shift Performance, Parts & Accessories manifold

    The come twin throttle body intake does have faily small runners and if you have a decent size cylinder head runner you will struggle to get the flow through the intake runners unless you weld up the sides on the intake runners to add meat and this isnt the easiest of jobs

    They just aren't a good manifold doesn't matter with boost or not.
    A good single plane will kill it all over the place.
    Guys that run the come ttb and say it works well don't no what there missing out on!

    Pretty sure tony Webb has a come intake on his turbo 355 it's making well over 1000 hp so they can't be to bad

    Yes that's the one mate. He slotted a 284 crane in and got rid of the 250 solid. So it was more street able.

    He got the TTB cheap so that's why he run it. He wouldn't do it again like I said.

    I'll try get him on here.

    Yeah stuff that mate. I've been welding for nearly half my lifetime and i know that would be a prick of a job haha. Im not interested in trying to polish a turd. Theres plenty of other welding/fabrication involved in the setup so i dont want to add another unnecessary element.

    ok no worries. Would be good to see how much power hes making on his setup. its pretty stout by the sounds of it. I'm sure i've watched footage of it on youtube before.


    If we had to choose a suitable manifold for this combo, what would be the pick out of say, Come single plane, harrop single plane, tp single or tp high rise dual plane. All with elbow and say 90mm throttle. Sure they'll all work, and probably work well, but what would the experienced turbo guys pick?
