▲%HP.

I don't think every one understands a solid triangle means difference, kinda like 3 dots in a triangle formation means therefore.

No, I'm sofa king we-todd-did. I mentioned delta % hp in another thread, even using the world delta instead of ▲.

? No one said anything of the sort, a good speaker speaks to his audience not above nor below, I think even using delta instead of difference may be above for people who are prolly eating lunch or picking their noses, or watching kids, or thinking about other things while perusing the thread. I ment no offence btw.

I'm posting in the wrong thread is what I meant, rofl.

Gents, the lower dyno is for comparison purposes only, nothing quantitative. This dyno reads LOW compared to the others I've used in the area. MX5 we did an hour before this was 135 pre tune, 149 after tune. This is with headers, exhaust, intake...they normally do 165+ with that combo. The lower number shows a high reading for two reasons:

1: The baseline is the BEST stock run of a strong car. I made sure to break it in with launch control and smooth rev limits at the time of delivery But we have many runs with it that are worse. I just put up the best one so nobody is disappointed when they do their own dyno with my tune.

2: It was colder that day. Forget the dyno corrections; if it is colder, a higher compression car will do better even when you consider the STD/SAE stuff. Dyno can compensate for baro, humidity, and temp. Not how much advance the car can run.

I'm glad others have put up the dynos because we spent about 4 hours on the dyno that day, and only one of many tunes allowed us to get that peak, which should be the norm IMO. I'm a 100% confident we will get it smoothed but not 100% it could be done with the stock port injectors.

PSI as adeets said I'm not 100% on, I was busy watching AFRs and have no control over that. Please keep it civil this is not a measuring contest just sharing what we can do with the platform. Having had all kinds of cars over the years I've not been excited by anything since first getting the miata. To see us being able to get 250+ whp on the stock motor in just a few hours of tuning blows me away. It took much more than that with the MX-5 but at least this time we have EcuTek to work with so that frees me up greatly to tune vs disassembly.

Hopefully we'll keep seeing more FI/NA setups to work with because with each we learn more and more. If not for the turbo BRZ I must have 40+ hours into between emails/tunes/travel/dyno, this would have taken much longer. I'd really like to see what the limit is of the stock motor on this with a proper tune.

@FullBlown @moto-mike

Ok so my buddy blew his engine in his WRX, so flatfour was slammed today with that tear down/rebuild so I didn't get my fuel pump/injectors installed.

New install date for fuel pump/injectors and fit test of full blowns radiator will take place on Monday June 10th, which means I'll be heading up to Wicked Big Meet this weekend with only 263hp. After the weekend and the install happens it will be a couple days while @moto-mike retunes it and we get it back onto the same dyno.

After that, well in to the future, smaller pully and E-85, and a method to control the boost with the 13 psi pully with-out a constant hissing noise for pump gas...

[Xero-Limit]

It's been a while and @Adeets stopped in to get it retuned with the bigger injectors. We tweaked the fuel ratios, timing, and cam phasing to pickup a bunch of hp top and bottom....note the now smooth curve on pump. Looks like we have some more room to go still, but we held back as a smaller pulley will be going on soon.



Sorry for the crappy paper, we have a totally different car on the dyno and don't want to screw up the screen there.

With the smaller pulley and headers this will be beast. I cant wait to see a few years from now when people start touching internals and upgrade to vortechs bigger units.

Let me make sure I am understanding you correctly. The reason that Adeets hits 275HP and everyone else flatlines at 255HP with the same mods is because Adeets has upgraded port fuel injectors? That's it?

I don't know what the other guys are doing with those tunes. We ran adeets' car on the stock injectors and with a mild overdrive of the DI ran into IPW issues at the top end. Using bigger injectors allowed us to run much shorter pulsewidths. With that said, we've learned a good bit before dyno session 1 and 2, so there are other tweaks in there. Yes, you can achieve good numbers on the stock port injectors, but IMO there are too many compromises compared to just forking over the 300 and then having the headroom.

i know first post is old, but why on earth would you post a poorly tuned graph to "show" everyone... I love it when people jump the gun to post sub par results. That makes me think you think its ok to have a power graph look like that.

Hi new guy! The man explained he was having difficulty getting the tune ironed out. You need to read and look at the graph too.

[tendogy]

Thanks for the response! I read through 50+ pages of Vortech threads today, and adeet's dyno is the only one I've seen that keeps HP climbing past 6k RPM and doesn't level out.

I'm no expert, had to google what IPW means, but I was trying to figure out if I should be impressed or skeptical

It's clear from your first posted dyno that you've made great strides in tuning this thing. Do you have any other stock pulley/pump gas Vortech dynos on the forum that I could look at for comparison? It's so hard to find good dynos...

mike is great tuner
