I have been doing some research on the pro's and con's of the ITR intake manifold vs the Victor x on 400-500 hp turbo honda's with mild cams(ITR,GSR,Pro 1's) and red line (8-9K).

I understand the size difference of the runners/plenum and how that moves the power down low for the ITR and up high for the Victor x but how much will I sacrafice with the ITR? I have been having some problems finding dyno graphs of the cars with ITR manifolds in this power range on honda-tech and evan's tuning, most choose the victor x for the HP numbers but where are the daily driver guys!!

If there is anyone that has a dyno sheet that would like to share I would appreciate it. Or others with first hand experience with the ITR or Victor x that would chime in!!

 

My lsv turbo made power to above 8700rpm, I was too afraid about dropping a valve on my dd going to 8900. I had a itr Im

266 whp @ 8psi

 

thanks for the info....really looking for cars in the 400-500whp range.

 

I'm using a An old skunk2 IM which is pretty much the same as the ITR IM. I'm running blox b cams. And made 522 I don't plan on changing my IM and I'm going for 800

 

if you're spending more time driving on the street than on the drag strip, i suggest the itr. based on the all the dyno comparisons i've seen, the itr kills the victor low to mid range, and the victor only making slightly higher top end power. you won't be sacrificing much! goodluck

 

Street driving itr? Do you guys realize with 4-500whp the power is useless on the street.

 

Nope its not at all. MT 225 50 15 I can dead hook 415whp in 2nd and 500whp in 3rd 4th 5th

 

SK2 manifold here, with CTR cams. 600 plus and im not changing a thing. Seems to work for me.

 

Im loving what Im hearing....any dyno graphs?

 

My current numbers in sig done on a skunk 2 pro series.

 

For those that post please give me some more info on your set up... thats is if you dont mind...

compression, bore, turbo....

for around the power your looking to make a skunk2 would be just fine. skunk2 has really good low end. either of your choices will work
