Suprised Ito hasn't commented on this thread :-\

 

I'll keep looking :-) Thanks for the pics! I was actually creating up to 5 rows per coolant passage. In some, there's only two. So maybe I can get something a hair bigger and go from there.

 

I've also seen them cut across the exaust port area as well..

 

How much is this supposed to drop the temps?

 

It's just supposed to remove heat away from hot spots thereby lowering your potential for pre-ignition/knock. Dunno if it would allow, say a 1 range hotter plug...I doubt it, but it "seems" like a good idea....

itll take heat away, but will show slightly higher temps. stevenkan said he noticed them go up, but only a couple degrees, nothing major

 

seems like it would go up a little. since the heat is no longer in the block but rather in the coolant. one of these days michel i will drive down there and check out this beast.

 

Michel , any updates?

BTW are you going to MADS this weekend? I'll be there again.

 

Not going to MADS unfortunately. Need to save the vacation time for a travel abroad :-) I screwed up one of my plates, waiting for it to arrive from Judge Ito here...I have to shoot a driving event at Moroso on Saturday ($$$) and I'll probably port the back plate on Sunday. I'm trying to get everything together in time for the NOPI drags in Tampa...this time I'm taking 1st in street tire class :-)

 

I knew about the plate that you chewed through. Thats too bad.

Make sure to post pics from the Mororso event.
