I was quite amazed that the car picked up as much as it did with the cams. I was expecting 20whp maybe, but no i got much more!

Setup:

Stock GSR Motor 173k miles
AFI Street Series turbo kit (57trim)
ARP head studs
ITR cams
ITR valve springs
Blox IM
Tsudo 70mm Exhaust (i cheaped out here )
880cc injectors
E85
Street Tuned on Crome Pro


Max boost was 14.5psi. Duty cycle on my Tru-boost was 42% on the dyno for both runs. The rpm pickup for the last dyno run was not working so i do not know the TQ that it makes now, although im guessing its in the 270-280 range. Peak tq for the GSR cams was 262tq@6100rpm. both dyno runs only went to about 8100-8200rpm. The vtec dip has been fixed now.

Overall im pretty impressed with the ITR cams. But for the $320 i paied for the cams + valvesprings it was well worth it!

The car's best mph before the cams was 123.48, best new mph has been 125.65 at about 2600lbs <---- need to put the teg on a diet!

 

im going to get retuned on the cams as well and should make about 450, stock GSR

 

Very nice, where does your VTEC engage now with the ITR Cams? Imagine what the gains would be going from GSR Cams to Pro-1's with the proper setup!

 

Right now Vtec is @ 5000rpm, when i had the gsr cams it was 4500rpm... i still think we can lower it a bit to probably 4800...

 

Nice numbers... I'm wondering how much HP you picked up just for using E85 vs 92-94 octane? Also how much more is E85 then 92-94 octane?

 

E85 is usually cheaper, about the same as low grade fuel in most places as far as cost. its usually around 100 octane in comparison I believe, i could be wrong.

 

I think for long-term reliability on the valve train the ITR cams are great.

 

Thats sick.

 

Well i dont know about power , but i know that off the WG which is 10.5psi i did 343whp with the ITR cams/E85 and i trap 119mph, off WG without ITR cams i was trapping 117-118mph, on pump (92) off wg i would trap 114-115mph... all that was at about 2615lbs..

 

Where did you get the cams? I cant find any place that sells itr cams?

 

i bought mine off a friend that changed his ITR cams for some Sk2's...im sure if you looked around and called some shops you could find a pair easily...or you could bite the bullet and buy them directly from Honda ..atleast then you know they are brand new!

 

was the gsr cam dyno on e85 also?

 

yes sir

 

Nice...that makes me want to switch my cams before i tune this spring...

 

it would probably be worth it!

just bought one myself.

 

Wow, nice gains. Definitely worth the $320 for 47whp haha.

 

Yes it is definetly worth it!

 

Looking good Myles - those are definitely impressive numbers for a bone stock GSR, especially on only 14.5psi w/a 57trim. Looks like TJ did a great job on the tune! We are looking forward to seeing all you guys down there again this summer.

 

hey thanks man!! yeah man TJ did a good job! he always does... im in the same boat as Bryce now just broke 4th gear at the track last night

 

Sucks to hear, I'd take this opportunity to shorten up your gearing and put a B16 3/4 in it, should improve your times/traps quite a bit!

Bryce and trannies just don't get along, haha!

 

hey myles. guess who has a b16 tranny laying around.

noticed the thread and thought i should say something. this car rips. especially when im driving it!

 

hahah yeah they dotn like him...im begining to think they dont like me either! I dont think i have the rpm to turn to meet the traps id like for B16 3rd/4th... i still have my old tranny that has 4th gear still good in it so i think im just going to switch that over...

**** for all i know youll want $800 for the tranny

it goes slower when you drive it

 

did you dial the cams in? or just threw them in and tuned?

 

Dialed them in..
