Any results from the ITB testing?

Maybe if we ask enough we can fully fund the project, and bend the laws of space and time for instant results.

Given its been nearly 2 months , and no results.


The conclusions could be


A they dont work ie minimal power increase or some other major issue

B They work to some extent but have drivability or some other major issue
C they never got arround to testing them for some reason




One would assume if they worked to any usefull extent (at reasonable cost benefit ratio) then their would have been at least preliminary results.


Hopefiully they do work, but given that other intake mods like the velox/versus and full blown manifolds didnt set the world on fire, its possible that the factory engineers did well and theirs little room for improvement. Without say major changes to head/combustion chamber and cams valves etc.

Creative solutions are needed to tune trumpets, when both your MAP and MAF sensor are gone :thumbsup:

So out of the box, the itbs didn't give overwhelming results?

Without tuning, out of the box. No

I think it's been long enough since the last time I posted this but if you want to see ITBs with individual trumpets and a MoTec to manage them, look at @zerobreau on instagram. He's had pretty good gains and the car sounds phenomenal.

Of course they require tuning. I'm asking about the runner/plenum configuration.

Interesting will need to be creative if no maf or map sensor used. What are they going to use for metering Air into engine with no pressure or flow data.

The info here suggests its compatable with stock intake so appears you could use maf, then second option was ecutek speed density which wouod use map pressure and temp.




So whats the advantage of using neither maf or map. ?

This kit doesn’t have open trumpets to air, so why couldn’t a MAF and/or MAP be used? Even if it was open to air, isn’t it the norm to tap into each TB manifold and run lines to a distribution block that connects to a MAP sensor?

It is cool, but Motec plus ITB hurts the wallet for those gains. I feel like if he went Motec then maybe more plans are in the works, maybe to do a built high compression and stroked motor running E85. 300whp all motor would be pretty sweet to see.

Can't use just a map sensor for itbs because the signal isn't very good at partial throttle. Most standalones will use a combination of map and throttle position (alpha n).

Nah we don't have E85 in Canada. Seeing as it's his track car and he competes, he might be able to get a hold of it but I highly doubt it. He did do his baseline on a different dyno, but the new one reads lower than the old one, so his gains are at around 60 whp, which - even if 30 of those could be attributed to his catless header - is mighty impressive

Impressive especially because with "classic bolt-ons" there is somewhat diminishing returns limit of ~ +40whp, that is hard to get pass. If ITBs will further enable getting more NA gains, even with bad price/performancy, they still might be desirable product imho, even if their sound or throttle response is not primary wish of potential customers. Expensive? Yes. But then again, NA tuning in general is expensive, nothing suprising. If they will deliver that is.

No way you get 20 horsepower out of these things. Especially with stock redline.

I doubt it's 20 but probably close to 10whp/10wtq. He's hitting nearly 180ft/lbs... all this on shitty canadian 91. I imagine 93 would be close to 15/15 over a decent header.



All speculation till we have a more thorough analysis.

20/20 would be on e85. Best fuel all around.

E85 gives 20 on it's own.

60whp gains? Dyno before n after?

Not necessarily

This would be for open trumpets, not with the provided manifold! With the provided manifold, you can use the stock MAF and MAP.

Currently, some fresh components are being swapped onto the motor of the NA test mule.

It's on his IG somewhere

Nah. More like 10-15. Same dyno, same car, same day. E12 vs E68.

20whp is reasonable considering 91 shows up as 6-8% for me and e85 usually is around 78%. Plus others have different mods and different tuners.

I didn’t see it.

Message him. I'm sure he has dyno sheets. I'd just feel rude doubting him like that personally. No reason not to believe the dude imo

60 whp is possible. I’m curious if it was gained troughout the rpms or just in the dip. I’m curious if he was verbalizing the change from a peak low to a peak high, but those changes weren’t coinciding at the same rpm so not really a delta change.

60 whp? Doubt it.

30ish whp with 91 and 35 to 45ish whp on e85

And that's with a header

:D ANY CHRISMAS PRESENT?...

Give up on this and go with the revolution dual ram intake. Much cheaper and similar results.

Whatever happened to this testing? Stopped, paused or didn't get any results?

Nothing from racer x either. F.i. is the only way to go with these things.

RacerX has teased some recent photos on FB(1-12) of their new manifold but it is not ITB.

When will peeps ever understand....lol. The only solution to these is the revolution dual ram intake with bigger throttle body. Much cheaper and similar results.

It would be great if you stopped spamming this thread with that suggestion.
Especially since the manifold is a known bottle neck with these motors. You know what hasn't ever come up as a bottle neck? The intake and throttle body. You're basing this on one dyno test with this intake, and they were hardly concrete/conclusive.

Just let the results come out from a reputable source regarding the ITB's, if they're still a major loss than by all means you can continue venerating the revolution intake.

The only bottleneck is the header. Speaking n.a. of course. Some real intelligence went into the intake design.

Why can't we have both Better intake Manifold with bigger throttle body and revolution intake?
Tune is big concern that someone works side by side hardware/tune to make it work right. Like ACE/Delicious/CSG all worked together on make the headers work


I think with the Intake Manifold tuned the front of the intake might not matter as much. Kind of like a Catback exhaust doesn't do much after the ACE headers.

They are on their second prototype and they plan on doing 4 total. RnD takes time, its not like its the only thing they have going on.

so... is this just another hype thread?
