I need oppinions.
Ok, in about 2 weeks or so I'm going to be having my car tuned using Hondata s200. I'm only aiming for about 250whp. I was wondering if it would be worth having it tuned using race gas. I can use 110, or mix 92 and 110 to get about 100 octane. I don't drive the car on the street but maybe once a month (just to get it out of the garage).I'll be running 750cc injectors and a walbro 255lph fuel pump.
I know I'm not pushing the engine, I just wanted to know if it would be worth tuning it on race fuel. Will there be any benefits or would I be fine on just plain old 92 octane.
Thanks in advance.

Yes, I've put about 300 miles on the car since last june. It's not a daily driven (or weekly driven for that matter) so fuel cost isn't an issue.

Yeah, I just didn't know if my car would be happier with the higher octane.

Re: I need oppinions. (b16ahybrid)
Yeah I would definitely go for a 50/50 mix but up your power goal to 300whp at least I personally would be after 300whp to 350whp with the mix. If you don't drive it far then run straight race gas and definitely shoot for 350whp. Those injectors are overkill for a measly 250whp.
Goodluck tell us how you get on.

250 is just the beginning. I am going to be building the block this winter and going for 400whp next spring. No need to buy two sets of injectors.
I wasn't to sure how much power I could get out of this engine as it sits now. I was only able to squeeze 226whp out of 9psi with the set-up I'm running now (seems low to me). The engine checks out fine, compression and leak-down are all good. Maybe it will respond better with the larger injectors and hondata. I'm going to tune it with just the wastegate first (.65bar) to see how much power i can get from just better tuning. Then i plan to up the boost and aim for a minimum of 250whp, if things go good I will shoot for 300whp but thats it. I'll have to make that decision as we tune. I've never dealt with this tuner before, There are only two local (within 300 miles) hondata tuners around so I chose the closer one. I talked with the guy for a while, he seems to know hondata pretty well, they have tuned it with great success. Comments suggestions advice on my plans are all welcome. Thanks so far.

Re: I need oppinions. (b16ahybrid)
Aslong as it not detonating which it shouldn't with decent tuning and straight race gas 350whp shouldn't be a problem. I have been to the dyno quite a few times now and the only thing that has stopped me pushing the engine harder is something always stops me from going any further, if not detonation with crappy pump gas its been the turbo spiking the last time I ran out duty cycle for my injectors. So yeah I would say if it is going well at least hit 300whp. It sucks to get home get used to it in a week or two then be thinking why didn't I get it tuned for more boost...

Re: I need oppinions. (turbozxi)
Yeah I see what your saying. I just don't want to end my race season prematurely. So you think 300whp on pump gas and 350whp on race gas will be within reach. Assuming the engine is in good shape.

Re: I need oppinions. (b16ahybrid)
Oh and also what are the upper limits of my turbo. It's a garrett T3T4OE .57 trim .63 A/R (got it at cheapturbo.com). When I bought it I didn't plan to run more then 300whp. But things have changed. If I remember correctly it's sweet spot should be around 15psi, it's been to long since I researched the flow of my turbo. thanks

Re: I need oppinions. (b16ahybrid)
I would use race gas from 250whp onwards for one its saves tricky tuning having to tune for pump and race gas. As a reasonable race gas tune should net you 250whp easily without danger on pump. Yeah the B16s have been proven to hold those kind of power levels stock many times.

ACT extreem pressure plate w/street disk. It's going to need to be changed when I open the engine up. It has about 25k miles on it now.

Re: I need oppinions. (b16ahybrid)
well personally if you are already planning to make this your 1st boosted motor and you have bigger plans why not save the money on tuning with race gas & contribute to the build up cost or tunning cost.
I think the question here is if it will be cost effective.
If I were you I would just do a full tune with 92octane and call it a day. 92 octane will not be the limiting factor in reaching 250whp.

This is my second boosted motor. I boosted the stock d15 about 5 years ago, and this engine has been in my car and boosted for about 3 years. So 5 years of booted bliss.
Cost effective? This car is my track toy, I don't cruise around in it, i don't get grocery's in it (anymore). It's my Toy, something to do to get away from work, bills, my house, etc..... something to alleviate me from the daily grind. So if running race fuel will be of any aid then thats how it will be tuned. Otherwise if it's pointless (sounds as though thats the census) and won't aid me in any way I'll just tune for 92 octane. I just wanted to get a little advice before tuning day. Thanks for you input it's all appreciated.
More input is welcome.

ok, thanks.
You run a thicker head gasket rite?
What did that put your compression at?
