My 99 T25 @ 10 psi with WI... dyno
 

Hello everyone, I am getting my 99 stock motor dyno'd today. I am running a t25 @ 10 psi with DO progressive WI. I am running only a Voodoo box for management and I have the HKS downpipe to a highflow cat with 3" catback exhaust.. Also should mention I upgraded the spark from stock coils to plasma blasters.

I am getting it dyno'd later today and I am just curious to see what people can estimate the outcome will be. I will posting pictures, and hopefully even some video later today...and hopefully talk to the owner about dyno discounts for us. Thanks and I am getting it done @ 5pm Pac time so I should have the graphs up later tonight.

You're missing lots of info here. What engine management are you running? What exhaust do you have?

Sorry thought I included it...I am a little excited :jerkit::crx:...I am running only a Voodoo box for management and I have the HKS downpipe to a highflow cat with 3" catback exhaust.

Good luck with the Dyno!

Thanks I am going to a place that does mostly high HP muscle cars, but the owner seemed real nice/interested in doing a miata...:)

Plasma Blasters?! :confused:

over 200whp easy. just make sure its tuned right.

It is a product made by ignition solutions that when produced cost 695 dollars plus shipping. It was made to replace weak spark systems (miata :giggle:) but is real big amoungst jeep enthusiasts. Its basically like COP, but I got them for real cheap from the deal of the day on FM so no need for COP. It was basically a direct swap, but I remounted them on the opposite side. They cleaned up my idle amazingly. Here was a old thread on m.net regarding them
http://forum.miata.net/vb/showthread.php?t=1894 here is a older picture of my bay you can see the major wire layout difference (and many things have been changed such as wire locations, the oil feed leaking union & more). I reused the NGK grommets on longer wires to compensate for the length differences:jerkit:

As for being over 200WHP I completely agree, but the management issue with the VB my major restriction. Its kind of hard to dial it in with my progressive kit.

g/l

what size is the turbo? t25 just doesn't cut it. My guess(and I am rarely wrong) is 196.4 rwhp.

214 HP/ 202 TQ. I said it first.

Not even worth posting up the charts (I still will tomorrow when I can hopefully scan them). Other than someone losing a motor or damaging something I had the worst runs. I had a couplers that kept busting and my tuning was crap. I had it running great, but at the last moment I enriched it before dynoing it because I was super scared ruining something seeing that I am 20 and poor. :(

Highest WHP sadly was 143.1 @ 4200 because the coupler blew off with a AFR of 12.11 & surprisingly torque on the same run was 181.19 @ 4100. He told me if I get things worked out a little better I can bring it back and get a discount. The whole way home I fixed my AFR...damn WI i underestimated its effects.

I WIN for being the closest!

Nothing wrong with 12.11:1 AFRs.

Why do you have to fix an AFR of 12.1?

http://i170.photobucket.com/albums/u...h_CIMG6525.jpg one video of it...I like the sound, but its so sad you can hear when it loses power after 4200 or so. I tuned it coming home (damn so cal freeways) and it runs great again. I may go back tomorrow...I am super sad

I completely agree 12.11 - 12.5 is awesome, but the problem is after that my WI and shitbox went extremely lean on this run. On that run I was already at 12.87 @ 4450 and climbing. I started running leaner than stioch and the engine went super retarded :giggle: literally. All the numbers above 4100-4200 either went to lean or too rich. I

Forgot the charts at home, but looking at other peoples information can anyone verify that with this tuned I should have tq & whp over 200? I mean my Whp did not even get to take off & my tq was already at 181 @ 4100.

The manager said that they had nothing to tune fuel injection yet (place does mostly drag domestics, but the guy is great and was amazed with a 1.8). Him and his co-worker said they loved the sound of the set up compared to there 454 V8 all motor stuff :jerkit: Thanks for all the input guys, and sorry that my bad tuning made this thread a waste. Hopefully should have new numbers in a month or so. :noob:

The points of COPs is to eliminate spark plugs wires. ;)

now, post the plots or ban. Sounds like the clutch is slipping on that pull....

visually yes, but fuctionally they are there to increase power to the spark yes?

I left them @ home, but the charts blow horribly. Running super lean shown in the video (timing retards big time) and the other one running with 10.4 AFR gets me no where. If nothing else I will take a pictures of the charts and post them tonight. :)

Funny. I was gonna guess 143.1hp @ 4200 and 181.19tq @ 4100. I shoulda said something. :(

liar!!!!!!!!!!!!!!! ;)

its a shame youre in cali...there are so many more options where emissions doesnt matter...

your EGM is definitely holding you back. Piggybacks are terrible on the miata. the AEM, Hydra, and Megasquirt are all good options.

Sorry for the disappointment.

To boost your confidence a little, a guy came into my buddys shop the other day with a hotside supercharger running 12psi and only made 175 HP at 6500 rpms LOL

LOL, thanks...I am building a MS2 but it had a bad outcome. I think I may just convert it to run MS1 with a CAS and be done with it. I hate the voodoo box, thank god I got it used. I love my tq though :giggle:

Agreed.

And... umm...:ugh: I think I may be the one who sold you the voodoo box lol, sorry it didn't work out too well for you, I never got to even try it on my car, but with some tuning hopefully you can get it to work.

No worries man you gave me a great deal and it's not anything to worry about. Crappy product good price! :)

As for the clutch if you are referring to the lack of power @ the end of the pull it went extremely lean. NB's retard timing massively when lean which I may think is throwing you and Scott off. If its somewhere else please let me know...because I am almost 100% positive I have no clutch slip. My brother's miata came with a real bad slipping clutch so I know the exact feel.

It was nothing to do with the graph, I was just saying that based on the sound on the vid. It sounded like at the end of the run the car was revving freely which made me think the clutch could be slipping, but you probably have more experience with bad clutches than I do, and if it was slipping, you would probably notice it when driving. Do you hit full boost when driving around? And are you on the stock clutch?

It's a possibility.

Oh and come on out to the west side miata/bunch of other stuff meets every other thursday in marina del ray, there's a thread on the cali CR forums. I need to check out some more boosted miatas, and I have still yet to drive one!

get a ms or hydra.

I never hit full boost or take it abouve 5K when driving around because I DD and baby my car. Yah at the end of the video is when it went lean and the NB retards itself dramatically which sounds similar to a slipping clutch. Yes stock clutch as well as stock open 1.8 diff.

NIce, yah I never have been to any miata meets because of my lack of time with work, family etc...but it sounds fun :)

BULLLLLLLLLLL Shit. That's not retarded timing. You either blew a coupler off and that sound was the turbo overspinning making all that noise, or your clutch is slipping like hell. No fucking way that's timing related though. Sorry. If it retarded like hell, it would just fall on it's face, not rev up like 30# of boost just came online.

Get your MS2 going. :)

My brother said he would start to diagnose the problem with the MS2 so I am hoping on that, but he just got a new job so he's a bit busy...:crx: You are probably correct on that video, that may be the one with the coupler blowing off because now I realize the retard would actually slow the progression of RPMS not increase it. I will try to post the other videos of the other runs and see if it changes. But it is very possible I hosted the wrong run, but work doesn't allow youtube so I am not sure. Almost 100% sure that is not the clutch because it pulled perfectly on the way to work with no slippage WSE. :)
