Going to Dyno tomorrow, Any advice?
So i have an appointment for a dyno session tomorrow to tune my MSPNP,
Is there anything i should point out to make sure the tuners cover? Like the After start enrichments so it warms up nicely. you know the small things that help. I currently have installed are: -305cc Supra light green top injectors -Rx-7 Turbo II fuel pump:giggle: -2.5 custom exhaust -16g DSM -fmic -mspnp how much WHP can i make with this set up? im looking for no less then 200whp? Thoughts to both questions? Thank you |
you should be able to make 200whp. set your spark plugs at .29 gap so they dont blow out. best if you have a cold plug heat range 7. bring extra tools just incase you blow off anything. make sure you have a full tank.

180whp
I wish I can log into megatune so I can tell you..but make sure you leave with good idle and after you get off the dyno..do a street tune also..if possible...it made my car run super smooth... |
What do you have for a radiator? If anything will limit you power-wise, me thinks it'll be your injectors. Unless you're absolutely clueless about it, you don't need the dyno operator to tune things like ASE. You can do that on your own time.
|
advice:
Tell them to go for MBT in every cell. Go richer if you need to increase spark to get there within reason. At less than 22* advance, you should go richer than 12.0:1 if its a street car...lower if track car. Make det cans for detonation detection, don't expect a knock sensor to do it for you. I could hear detonation through the det-cans that the KS wouldn't pick-up. Get a log for the final pulls. This is the stuff I did when I tuned, someone will probably say that I'm wrong. |
hustler what are det cans ??? and how do they work?
|
It's like a stethoscope for your engine.
|
fuck the small things, tune the important things like spark.
|
right now i have cheapp autolite platinum and would like to get some NGK's.
Which NGK plugs do you guys recommend? a part number would be nice =D ^_^ |

I'll also say 180whp on those injectors. How do you expect to make 200% of the stock whp on 113% of the stock injector flow capacity(265)? Do you also have a rising rate FPR or something you haven't mentioned? |
don't go over 82% duty.

i have a cheap'o ebay fuel pressure regulator, but its not installed. i took it off and put the stock fpr back on when i installed the mspnp. i thought fuel could be controlled through the MS?
should i put the FPR back on? do i need one installed? i have a rx7 turbo II fuel pump installed and i know it pushes out over 200LPH |
your injectors max out at just under 200 whp. that's just how the math works out, doesn't matter how much your pump can flow or how much the MS tells them to open, they can only open so much.

that's kinda precise there Mr hustler.
Personally I aim to never breach 85% (and currently don't go over 65... (bit overspecced)). Everything I've ever read/been told is to aim for no more than 85%DC. That said I've known people get to 90-95% with no issues, but that was their risk, and not mine. The closer you get to 100% the higher the risk that you'll lock the injector open/closed. Saying it'll happen at 82-87%DC is just plain wrong though. |
im off to autozones to pick up a new set of plugs and then to the dyno, let you guys know the results after =)
|
let us know the process you went through to tune fuel and spark on the dyno!

Viel Glück auf Ihrem Geburtstag!

anyways i just got back home and here are my new specs: 168.2 rwhp 155.8 torque All @ 10psi im a happy camper! :skid: |
Congrats! A little lower than what you were shooting for wasn't it? Were your injectors holding you back?
|
Im not EXACTLY sure but i do think that that's what it was..injectors =P
its ok though. the boost the car is making is already crazy for me HAHAHA. Like i said IM HAPPY =D Pulls VERY hard The tuner also suggested i get a new coil pack since mine might be a little to old. its the original btw. he said the one i have is a little old and cant really keep up in the high rpms. does this sound right? |
might as well get COPs, talk to savington.
|
COPS? ok , time to study =D

COPS = Coil On PlugS. There are Toyota COPS that can be fitted relatively easy and somewhat cheap. If you need to get new coils, might as well go COPS. How to: https://www.miataturbo.net/forum/t12704/ |

Isn't that a little low? |
will post log, and dyno chart

Isn't a 16g basically barely even on its compressor map thus completely out of the efficiency range at only 10 psi? Perhaps that is why 10 psi is only the 162whp.
That said though, you have 162 rwhp in a ~2200 lb car! You've added 60% more power than stock, and that's nothing to speak lightly of. Rock on. -Ryan |

evan, don't you think a 2/5 inch gap would be a bit large?
now railz, post your shit asap or suffer great wraith. |
160hp is cool...

If you look closely, your wraith is cross-eyed so I've added another
Hes more one eyed than cross-eyed |
omg, sorry guys! been so busy past few days getting my car ready for paint!
promise logs, dyno chart and anything else you guys want will be up later today! thank you ^_^ |
