Are these good numbers for 7 PSI?

[Captain KRM P5]

i have another ? what is axela?

axela is the japanese name for the mazda3

no updates so far on my car, but it's going in again to try to get more power out this time. I'm probably not going to run any higher than 7 PSI for safety reasons. I'll post up my results.

Your graph looks like it needs more timing.
Here's some work my tuner did with a 2.0 engine on 8lbs, that isn't perfect but that was due to the fact that the stock fuel pump has problems above 380hp on 93octane.

35 horse per psi on an FS motor??? Ummm....

 

[Reffoxel]

Not an FS motor. It's a 11:1 compression, bone dry stock Honda 2.0L

That makes more sense... 11:1 and the cam profiling etc makes a lot more sense... I was going to wave a serious BS flag if you were claiming that on an FS motor since the best anyone is yielding is around 15 horse per psi.. maybe 16... what is the base horse of that motor (aka how many horse per psi were you pulling out of it... 18-20 hp/psi is usually beyond good and typically unachievable based on my knowledge.. for a 2.0L)

Base for the k20 NA is 154whp. Heres the baseline dyno run. the gap is due to a rpm pickup losing signal.

hahaha the VTEC jump is hysterical how well that shows up , still 30 horse per psi... that seems ridiculously high, but you've obviously got clean before and after etc... I don't know Honda at all, so that is likely where the gap is in this deal.

 

[Reffoxel]

the vtec is about 3-400 rpms low, anything higher it just blew the tires off when vtec hit, the jump was more than insane shall we say. (btw this is Ref's tuner talking aka roommate Justin from SCI Motorsports)The car is on k-pro, it enable the user to tune the optimum hp and tq per 10 deg. rotation of the camshaft then after blending the curves take on a whole new live, by far one of the very best softwares I have ever worked with.

 

[TurfBurn]

Why is that the K series motor is doing that kind of output for the boost when the B series dynos I look up require around 12-14 psi to put down close to those numbers... granted, it is .2 liters different... but was curious if there was something particular between the two that caused it... was it with race gas to run that kind of compression etc to pull that? or was it 93 (I'm seeming to think you mentioned 93).

 

[TurfBurn]

I found some other dynos now... non-intercooled K20 at 7 psi did 258 horse... so 8 psi and cooled... I can see it picking up a fair bit more...

 

[Reffoxel]

the compression always helps. I have always been a huge fan of compression and boost. Nothing unsafe about it as long as you understand timming. It was on 93 oct. I am rather embarased with the aggresive dips in the curve in the higher rpm range but no aftermarket pump=no more power.

yeah you honda guys are spoiled with all the toys and knowledge of those motors and tools for them... I'll get a lot more out of my car with the next round of tweaks, and there are a few things to do yet... next summer will be a great time for me as I'll have everything in place and make a run to see what the car is really capable of in the end... but running out of money, and winter isn't that far off... so it'll be in storage by the end of October most likely.

That is a turbo kit my partner chad and I designed. It is by far the tits when it comes to k series kits. I hope to duplicate great results with ref's kit and tuning. We will be tackling his car with unichip and we willse just how far we can take it. I have done good things with uni and I hope to do as well if not better with it on his car.

I run higher compression than most for a big boost motor... I'm running 8.9:1 and most on here run between 8.0 and 8.5:1... I'm aiming for about 22-25 psi max and I'll just eek out whatever I can get at those boost levels and call it good...

I can't convince you to go Microtech eh?? Great units for the price, and a lot of control to be had... easier for end user adjustments too... but the unichip does do a good job as well I agree, all depends on what the customer wants/needs in the end.

I like at a min. 9.0:1 but most are around 9.5 to 10.5. and we run up to about 25 or so psi. Chad's car (my partner is about 10.4:1 and right at 25 = 627/468. on a beefed up bottom end).

So depressing.. it makes our numbers look so tiny on these cars.... I still love my car far too much... and I hate to say it, but in part... becuse it's NOT a honda LOL... I like Honda's, but just too darn many of them.. nothing unique about a high horsepower Honda.

well I'm off for the night... and we should probably go back on topic for this thread...
