hey guys, i was thinking, has anyone ever seen a turbo ITB setup??

 

yes, tony the tiger has itb's on his 12:5:1 cr integra gsr, gt28rs at 12psi

GT2871R now. I dont think he has posted any updates yet.

&lt;Edit&gt;
Also, EDO has done some ITB/Turbo testing on the K series.
&lt;/Edit&gt;

 

i thought i saw someone with a turbo R put some on his...

 

all info aside, i thought it was 11.5:1. Has it changed?

lol, yea 11:5:1.. im aretard when im tired and hungover

 

so do you guys think its worth the investment?

 

Has anyone else besides Tony tried it and have any results to share?

 

id like to see how that works...

 

Sorry guys, no dyno plots or new videos yet... The only reference I can offer is my old GT28RS video you've all seen a while ago. The 28RS turbo didn't last and took a crap so I opted for the larger GT2871R (about a couple of months ago); which meant I had to change everything around it to suit the larger turbo

I am still testing and experimenting with different plenums for my ITB's. I've also dropped my compression ratio to 10.5:1 right now after the turbo upgrade. 94oct pump gas and a turbo capable of 400WHP won't mix. I don't look forward in making any huge numbers, but rather see how the car performs differently with ITB's. Most likely I will be making another video for you guys to compare because dyno just doesn't show much about the ITB's

 

These are some videos from about 2 months ago. Setup as follows:

B18C1 1.8L GSR stock sleeves
Forged internals, 11.5:1 CR
GT2871R @ 14 psi
0.86 a/r T25 turbine
Internal WG, HKS T25 manifold
AEM EMS, stock ignition
RC550 injectors
Hayward/Jenvey 51mm ITB's
ITB plenum (2700cc)
Water/Alchy Injection System (175cc/min jet)


First video -- boost/throttle response:

Second Video: -- Boost response

Third Video -- low-end response and midrange
http://jr21777.0catch.com/Tony...e.wmv


These are some vids just so you guys can get a grasp on how the car behaves with ITB's. It's hard to do a solid comparison, but at least it's something fun to watch

 

Tony, what was the cause for your 28RS taking a crap?

 

hey tony, do you have any pics of your setup?

 

How's the manifold pressure signal with the ITBs?

Autronic suggests running boosted ITB setups in a hybrid MAP/TPS based system where TPS and the manifold pressure sensor is used to calculate fuel delivery. I beleive the MAP sensor is then put in the plenum so that it gets an accurate measure of the available pressure to each runner and throttle angle is used to approximate how much air is actually making it in the motor.

Too much anti-lag and insane backfires shattered the bearings

Check out one of the threads in the fab forum for some pics of my setup:

I have it set up in a similar fashion with the AEM software, using throttle% vs additional injection maps along with the MAP sensor.

The GM 3bar MAP or the stock Honda MAP sensor had really poor resolution near the 0-vacuum regions and never worked out. I've then swapped to an AEM 3.5 bar MAP sensor and it had great resolution between -0.15 and 0.00 PSI ... I have about 4 load scales between -0.15 to 0.00 PSI which took care of the weak vacuum signal problem and has created enough resolution for fine tuning

NO
Unless you have $$ to wast. I really don't think its worth it at all.
What are you plans for your car?

 

Tony those links are dead!

probably full-race stage 3 gt
built b16 block
built b16 head
walbro 255
rc 550's
p28 w/ hondata s300
much more.

Not worth the time and money to run ITB's for that setup at all.

I ran out of bandwidth!

 

i wasnt even thinking about running ITB's w/ my setup, I was just wondering if anyone ever did ITB's w/ turbo.
