1998 ITR, 60k miles
*AEM intake
*GReddy exhaust
*B&M regulator
*Stock ECU, cams, cam gears, header, cat, etc.

1st run(stock manifold):
160.0hp/129.9tq
ignition timing 18btdc, fuel pressure 40psi

Final run(5th run w/ AEBS manifold):
168.0hp/135.0tq
ignition timing 20btdc, fuel pressure 50psi

there was SOME loss on the low end until 4000rpm or so, but after that, it started cranking big time. definite bang for the buck. imagine what it would do on a motor already making 180 or 190 at the wheels! thumbs up from me!

 

ok, but what was it before you changed your timing and fuel pressure.

what he said

Only reason we ask is because you can probably gain power just by tweaking that stuff with the stock IM.

Still sounds like a nice "bang for the buck" part though

Thanks very much for taking the time to report your results here. </TD></TR></TABLE>

yep.. i would expect low end loss with intake manifold, at least from everything else i've read about up until aebs. - what he says sounds more realistic.

 

with no timing and fuel pressure changes, there was only about 3hp gain across the board, and likewise on the torque. to extract the full potential, we had to beef it up a bit on the fuel.

regardless of AEBS claimed results, this is still a bang for the buck mod, and i would recommend it in a heartbeat. i've been tuning for a while, too.. knighton can back this up. i'm old skool H-T.

 

sounds good, yet another positive review for this manifold. If I had some cash I would give it a whirl on my very non-stock ITR. But Id be forced to port match it to the head

Thanks for testing Mike K.

Did you by chance dyno the ITR with stock manifold and 20degrees timing, and 50psi fuel?

Wondering how much hp that would add on a stock motor, or if it only adds power once you have the manifold.

 

Nice. Good bang for the buck. Wish I had picked up 8 hp from this manifold Got any charts you can post?

 

nope. we did 6 runs.

run 1: as is, stock manifold
run 2: installed manifold
run 3: raise fuel pressure to 44psi
run 4: raise fuel pressure to 50psi
run 5: raise timing to 20
run 6: let it cool for 10 mins and run it again same as run 5.

between run 5 and 6 it only picked up 1-2hp average. nothing significant.

hope that helped. later....

yea, they claim 15hp right?

i learned not to believe claims after i was into hondas for a month or so.
only thing that lives up to claims is a properly installed nitrous sytem, the toda header(IF there are manufacturer claims), and DRAG turbos.

every other product has been off by a decent amount.

 

any dyno plots...these guys need to make something for the gsr.. hey i thought mike K was out the honda game...lol...i guess everybody is stuck here

I was wondering the same thing. I'm not dismissing the AEBS manifold as useless, but there has yet to be a straight back-to-back test showing just the gains from the manifold. It seems like we've been seeing a number of instances where a baseline is done, and then the manifold is installed and "tuned" to varying degrees. What would be more conclusive is a situation where whatever tuning tools available are used to extract maximum power out of the stock manifold, then the AEBS is installed and tuned using the same tools.

Either way, thanks for the testing Mike, and I too can vouch for your H-T "old skool-ness".

 

My question to everyone else is why would you want an untuned motor? That doesn't make sense, if you flow more air, you need more fuel, period.

Glad to hear ANOTHER person with good results!!

 

Can you post a graph?

I know Austin is testing his today, I'm wating for his write up.

You may loss power with the same set up on stock IM.

 

no charts sorry. wasn't my car. i'll ask around.

If this is the case, then the stock ITR should be tuned for max power before installing the manifold, and then tuned again after installing the manifold. The reason people want to see back to back untuned dyno runs is to see what kind of difference THE MANIFOLD ITSELF is good for as just a bolt on part. It would be the same as saying you gained 10whp from an AEM intake if you tuned after you installed the intake and not before. Most people dont do much tuning after installing an intake though but they still gain a handful of power across the board. Anyway it sounds like the part has some potential

Actually, my car was tuned to a tee with the stock manifold, the AEBS intake was installed, and the car was again tuned to a tee. That is probably why I only gained 2-3 whp. If the car had been untuned with the stock IM and tuned with the AEBS, the "gains" would have been more impressive.

anyone who relies on untuned numbers will be misled.

a part that is added never makes what it is designed for UNLESS the fuel has been adjusted to ensure the the power is made in the intended rpm range.

Inexperience is why people ask for "what the part made without tuning". The people who usually say this have never tuned their engines or don't even know what is involved in the process.

sorry but 20 btdc on a stock ITR? you actually think that would be the best tuned setting?

.....I've gone beyond this on a stock itr. If it makes power, why not? It's not like it's a turbo application.....

 

Hey Mike K.. Good to hear from you.. I thought you got out of the Honda scene..

Almost time for a trip to Vancouver for some table dancing????

I'm not familar with your exact setup, but it seems then that we can basically conclude that this manifold generally makes around 3 whp, not the (sometimes much) higher figures some others have claimed.

It doesn't seem to be much larger than stock (in which case an argument could be made that the gains would be far greater on a very highly-built motor) and obviously the gains will vary slightly with each application, but it still seems to be a somewhat cost-effective upgrade, if not the incredible bang-for-the-buck that it was being touted as when it first came to everyone's attention.

With all the recent buzz around this manifold, I'd be interested in seeing some comparison testing of other manifolds on the market, though I don't think there are many in the AEBS price range.

 

Well, my car was tuned before the manifold, and then bolted on, dynoed, and then tuned again.

 

Not bad at all

And those gains w/ the AEBS Manifold are over a Fully Ported & Polished ITR manifold...

right?
