Hmmm seems low to me at high boost. You running a 2560?? I'm looking for 300rwhp at 15psi on my 2871 and a fully built motor.

Let's see some timing and fuel details here.

Still 300whp is nothingto shrug at in a miata!!

Just out of curiosity, did you log any of your dyno runs (using Megatune)? If so, I'd be interested in seeing them.

275whp from a built 1.6 with a 2860RS at only 14psi is low?

i didn't get any data log - he didn't even bother using that..

I am happy about the tune. I don't know why i didn't make more power at higher boost. my set up is begi s -3 with gt2860rs. tune with open exhaust...

I will have to say that this guy is amazing and knows exactly what he's doing. It took me no more than an hour to tune this car. after getting it off the dynapack he also street tune it. He knew exactly where everything was on on MS.

I will post up the graph tomorrow also will post up the spark map and ve table...

Do you still have the stock exhaust?
How conservative is your timing up high?
A/F too rich?
What injectors are you running? 550's run out of steam around 300hp

260whp/252wtq will roll c5z's...not a c6 though.

The point missed by so many is probably because there are no dyno sheets. On high boost he's got a torque number from a 1.6 that would yield way high hp numbers - like another 50whp at least. I bet the intake manifold is reaching it's limit right around the torque number and as the rpms continue upward from there, the hp curve does not.

I bet you're right.

Need more data. I didn't even know he had a 1.6 or a 2860rs until it was mentioned by someone. His sig is a little bit vague.

I'm talking about their intake manifold. They just developed it with the guy posting above ^, and from everything I've read it should really open up the potential past the 230rwtq mark.

I'm no expert, and without seeing where your torque is dropping off it's hard to tell, just an internet hearsay of a guess.

If you're running the S3 kit then I'm sure you know enough about Corky's expertise and the quality of their parts.

I'd also like to see a log...I'm at 72% duty at 261/252 with 550's on a walbro 255. I'd also like to see some AFR action and a spark map. I bet the race-fuel is helping your cause a lot. I'd like to see what it does on pumpgas.

Once I figured out wtf I was doing on the dyno, it took me about 1-hour to get everything to where I thought it was right. With that experience, I think I could get a car tuned on the dyno in 1-hour.

How's drivability?

Missed the part where he was on a 2860 and a 1.6 Sav, and I was only commenting on his high boost run.

But thats a fuckload of torque first off for a 1.6 and secondly considering your power numbers..

Lets see those dyno graphs!!

I want to see the AFRs and spark advance table in your "boost building" cells. You have their standard cast manifold, right?

Use a digital camera. Put the sheet on the floor at your feet, use the flash, and don't aim straight on- just a little off so the paper doesn't reflect flash right back at the lens.

I really think it it a combination of using 550cc injectors and possibly a stock fuel pump. I would also like to see the AFR table, but my guess is that you need some 750cc injectors and a Walbro255HP pump to actually see numbers where you should be at 20Psi.

275hp out of a 1.6 at 14psi is great though. My car has around 300hp and I spin my RA1 in second gear in a straight line if i get into it just a little. Very fun, but you have to be extremely careful.

I was in 3rd gear on concrete with 225 rs-2's and thought I blew up the rear end or tossed an axle because the car was pitching sideways...turns out it breaks the tires loose in 3rd below about 60* ambient, lol. AutoX-ing this car is a real challenge, but a crowd pleaser.

Our cars rule, lol. I really want to see what these cops do to whp and torque.
