Best HKS 272 Cam timing FP RED???
Hey guys just looking for a little advice here, I have been searching the site for info on cam timing for these cams and couldn't find anything recent. I want to change it up because i'm leaving power on the table with my current settings.
(The car made 457whp and 398wtq at 28 psi on 93 with pouring tb shaft seals and a sideways throttle body gasket)
What advice can you guys give me on the best settings for these cams to make good power across the board and have an aggressive idle.
Thanks in advance

i don't know if this helps since i did not had hks 272, but, my hks 280/280 were set to 0/0. although i had heard that the optimal for hks was +2/0. Same story also with my cossworth 272/272. I made lot of test on the dyno with both set of cams and the best result was always 0/0

Thanks for the reply guys, I have them set at -3/-3 currently as that seemed to be the consensus from reading countless threads that gave me no solid info. I will say that at this setting it feels stouter across the entire power band. I saw people mentioning -4/-1 but were losing bottom end punch. I have virtually no lag currently and want to keep it that way. My only complaint at this setting is that my lope is mostly GONE. It had a mean idle at my previous setting of +4/-
I do understand now that I left some power to be had with the HKS cams. They were one of the only mods done to the car when I got it and I should have changed them when I built the head but Im going to stick with them for a little while longer.

The Red has boost to spare on the stock motor, the cams aren't really a limiting factor.
OP run the cams straight up. They're not very big so timing change aren't going to give you huge tangible gains. And since the timing change is static, its really just going to shift the curve left or right, not make gains everywhere. And you're not going to get a really agro idle with those cams without Mivec to shove in a bunch of advance. If you want the agro lumpy idle, get some GSC S2's.

Don't mean to steal the post, but I currently have GSC S3s and I don't really like the cold starts and don't plan on making 700+ hp (drag it, etc.) on my 2.3L, would the the GSC S2s be better with cold starts, etc.? Also, with maybe a FP Black or GTX 3076R turbo would it be possible to make 500-600 hp on 93??

The R2's seemed to work very well. Unfortunately I only go to drive the car about 500 miles before I discovered an issue that will require the engine to be gone through again. But the 2.2/raceport head/R2's/FP Red made 24psi of boost at 3650-3700 on 91 octane pump gas. I'm hoping to have the car back up and running by mid summer and I'll have more data then. But I would certainly choose R2's for any 100mm stroker motor (2.3/2.4) or for a 94mm (2.2) motor you don't plane to rev past 8500-9000 or use for drag racing.

Generally spending time working on cranking pulse width, post primer enrichment, ISCV step tables is where a lot of cold and hot start magic happens. I'm not a tuner though. Aaron at English Racing does all of my laptop work. My tuning skills are limited to "maintenance" tuning.

Yes, it's an Evo8 3rd gear and I have a 4.31 final drive. This was also running no wastegate duty cycle in the tune, so yes, going to E85 and having the WGDC cranked will quicken it some I'd imagine. The car was quite snappy and very fun to drive.

Not sure, I've never tested it. Their is good evidence that the R2's lose no spool to the S2's if you have mivec, without mivec they lose about 150-200rpm IIRC.
