Intake manifold for turbo b series
Hi to everyone,I built a sleeved B16a turbo with gt35r and itr cams,and I have a edelbrock victor x intake but many forums they said is to big for set up like this.
they suggest to use skunk2 ultra street.
There is someone with experience on it??
thanks

Re: Intake manifold for turbo b series
A design with longer runners like the Edelbrock Performer X or Skunk2 Pro would have better torque and response in lower RPM. Victor X only really shows gains north of about ~7200RPM.
If it's a street driven car I'd consider one of the above manifolds with a matching throttle body, 68-70mm. Although a GT35R is already on the large side for a street turbo Honda, your powerband and spool will already be pushed to the upper RPM based on that.
Not sure it'd be worth the cash and hassle for you to swap it all out.

Re: Intake manifold for turbo b series
If you will be like 9500++ and 600++hp target 1,8-2 bar victor X is perfect.
If you are more daily based 9000-9200 max and 500-550 hp then probably smaller would be better.
If you still really want to spend money go for better cams. It will be much better money spend that changing intake manifold.

Re: Intake manifold for turbo b series
I have 0.63 a/r turbo housing 0.82 its to big for 1600cc displacement,my rev is 9400 and I want to make around 600.itr cams I think will be perfect for my goal other cams like pro 1 is extreme for my set up.
i think the victor x is better for drag and for engine to rev up to 9600 I have friend with the same set up and if he change gear before 9500 and drop before 7300 rpm is a fairly laggy.

Like I said, the Performer X or Skunk2 Pro would be a better choice. Ultra Street would still keep the power towards the upper end, but would likely provide a bit more mid range than the Victor X.

Kelfrod 176-t and GSC T1 cams will do for midrange what no intake manifold can do.
For 600 - 650 id say water/methanol and .82 a/r.
600hp on 77mm stroke with good spool is very difficult.If you really want 600 i would do GSC T1, keep the victor x and change the compressor wheel/backplate/cover to a newer design.
You want to replicate GTX3576 or something with smaller/lighter compressor, that will create less resistance to the turbine wheel due to smaller lever and weight and higher rpm of operation. Speak with TheShodan.
What manifold design you have?

Re: Intake manifold for turbo b series
I have ramhorn manifold and 81mm pistons itr cams is enough for 600 (not at wheel maybe) and 63a/r also they are many examples...my turbo is with billet compressor wheel like gtx.

Re: Intake manifold for turbo b series
Both kelfords and GSC cams are for better midrange (and top end but we still focus on mid range. Best top end are pro1+ but just top end and will require lowest back pressure possible)GT35 turbine wheel in .63 a/r has less flow from gt30 in .82. In a normal dyno normal setup GTX35 .63 should not do 600 except if you use water meth or super big setup with top mount / pro1 etc.
The last gt35 .63 data i have is b16 84mm and hit 500 to the tyre on premioum pump gas.With 0.82 could hit a good 30whp for that extra 5lbs turbine flow. More with better fuel.

Re: Intake manifold for turbo b series
Balor_gr I understand what do you mean but I want to make better mid range from intake and not from cams...tell me something....you thing is not possible to make 600++ with 0.63a/r???????

Re: Intake manifold for turbo b series
You might hit 600 on .63 on gt35 but on the best fuel or water meth / cams / manifold / intercooler / butterfly / HIGH cfm head etc.. I still believe on a normal reading dyno 600hp on 1600 engine on .63 a/r is very difficult.
Unless you use racegas...
I know... I wish they had .70 a/r turbine housing on garrett...
Trust me the best mod you can do from know on is either spray by injector duty cycle W/M injection (aquamist) or good cams assuming you have strong valve springs...
W/M injection will help use higher advance for less exhaust volume/heat and higher hp. Dont change intake mani victor x worked perfect for engines that hit 9500 rpm for many years and still does.
If you dont allready have big throtle body i believe 70mm skunk2 alpha will work well and its cheap.

Re: Intake manifold for turbo b series
Intake might give 5-10 whp middle. Cams will give 20-30whp on the mid range and more and the top end. More mid range = better spool also.

I think OP would be happy with the PerformerX.

Re: Intake manifold for turbo b series
Thanks for the reply but I have different point of view...all these cams you said is perfect but not for cars because they are stressing to much the valvetrain and my car is not only for 2 days per month...trust me is very easy to see 600 with 100ron and c5

Re: Intake manifold for turbo b series
There was a dude that was sure he did 630 wheel hp on a GTX3071 because that was what the dyno showed...
