1j 264 vs 272 cams

[HIZOKU]

You talking about 4th gear?

Hmmm very interesting!! With stock retainers and springs aswell.

If you dont mind me asking, what ecu is he using?

hey mate, got my customers car tuned with 272's, on 13psi it made 380rwhp.. i wanted to go to 22 psi and dial the cams around to make more power but there was a software issue with the ecu and it needs to go back for warrenty... in the midrange it leans off by itself no matter how much fuel the tuners puts in and he said over 13psi theres gunna be a noticeable lean spike

runs and sounds awesome, drives like a dream... im totally going 272's in my car, unless anyones got a direct comparison saying they can feel 264's kick in earlier and giving a better mid range on the street..

otherwise, im happy! ... btw was with standard springs and retainers, absolutely tears tyres off in third.. loves it

yea 4th or 3rd,2nd and 1st too quick to tell, was playing around yesterday in 5th and make 18psi by 3400 :O

1st 2nd 3rd i cant tell as i brake traction soon as boost hits 4th is only gear i have atm till i reset up the rear end and new semi slicks but yeah my one is 4th but yeah i dont hit 16psi till3500 or 3800 but yeah my boost is like a on off switch LOL

heng i put an ems stinger in, its just a street driven car so it didnt need a "top shelf" ecu, itll probly see the drags a few times and never again.. i myself tho am going to run 272's in my 1jz with a 35r for 22psi and im gunna run it with a vipec ecu, antilag and launch control, excellent 3d mapping ability, cold and hot tuning, its a great ecu and my tuner (sean at all star garage) recommends them over anything..

[pandaah]

well like i said.. unless anyone can actually prove 264's give better power results..

after reading the supra forums link above, i think i may have just changed my mind to putting in wild 264's ?? what do you guys think after that read

Isnt the SF thread enough proof for you?

Or would you prefer someone with a butt dyno to comment?

[Disturbed1]

was more case of price and availability when i picked up my 272s.

will post up dyno results with gt3040r when its tuned. (might be a while though)
