Who here is using the 00 CTR cams on boost? What kinda #s are you seeing?
Has anyone played with the cam timing to deal with the increased overlap?

Jeff Evans also had some results posted on his site too. I dont know how much information you are actually going to get from here, but good question. You should expect these anwsers: search, been posted, take it to the dyno, ask Tony, and find out for yourself
I would like to see some actual technical input for once, but we'll see.

I'll tell you why there is no concrete number, because there can't be. Every setup is different, especially when we're talking about camshafts. Intake and exhaust manifolds, cylinder head, turbo, downpipe/exhaust, etc all come into play when choosing what's right for your setup.....

Listen to this guy, he knows what he is talking about. A couple of years back Tony told me I should put ITR cams in my set up and they would make a BIG DIFFERENCE, he was right. Check my old thread below

yeah i know there is no one universal setup for every car, but i read on one of these crazy forums [mighta been evans] that the CTR (different than ITR) had increased overlap that was good for n/a but not so great for turbos and something like +2ex/-1in on the cam gears helped dial this out....
Like I said i "read" this in a few places but that doesnt necessarily means its true, i was just curious what other boosted CTR users were running as far as cam timing....

ok lets say i have a POS Drag manifold and a turboentics t3/to4b "S" Trim, .63ar, 3" downpipe back on basically a 9:1 b17 engine...
Its a pretty crappy manifold i know, how much overlap do you think I can get away with? Should I try dialing some out given my setup on these cams?
And yes, i know tony is smart

The 00-01 ITR cams are identical to the EK9 cams.

Heh I learned this the hardway but you think you could elaborate some? Im curious to know the technical reason drag + ITR/CTR are no good? I mean beyond the fact the manifold plainout sucks what is it about the design that makes it bad for these cams?
Thanks man!

This thread reminds me of an ITR owner on here, he made like 58whp more swapping from his ITR cams to GSR cams. I was always puzzled by that BUT I can't remember what manifold he was using. I need to go search. His screename is like turbotyper something like that , he has a hacthback that he swapped all his stuff over to now

hmmm this is interesting stuff so it seems like the effectiveness of the ITR/CTR cam combo are really impacted by the manifold your running?

This is what I found out on Turbotyper's old set up when he swapped from ITR cams to GSR cams , it shows on page 2 of this thread
https://honda-tech.com/zerothread?id=284031&page=2
Now I know aftyer that post he made a post about a new turbo manifold he made BUT I don't know what he was running when he swapped the cams. Also he was running just an ITR intake manifold which people were saying could/would affect how the ITR and GSR cams worked on his set up. Makes sense since the Edelbrock mani was designed for 7k-10k where as an ITR was designed for an ITR motor running up to 8400rpm initially

Re: (Boostfed.com)
Cam overlap is for cars that have low pressure in the exhaust manifold and intake manifold. With a drag manifold, you have high pressure in the exhaust manifold so you are just going to have a good amount of reversion. There is your tech answer.

Given the senario of CTR cams an Inline pro manifold have seen to be successful with some cam tuning from Jeff's point of view I belive. Correct me if I am wrong.

Hmm thats weird isnt the inline pro manifold almost identical to the DRAG except it has the wastegate on the collector instead of the #1 runner?
