Dyno after breather mods and tune. Thoughts?
 

Just looking for some feedback. Baseline is with Fast Intentions exhaust only. Top line is with FI exhaust, ARK high flow cats, Stillen G3, Motordyne M370 and Uprev tune.

Looks to be on par.

Looks GREAT. Great over all gains

314 Whp
265 Wtq

That's Real Nice

Thanks for the input.

Any suggestions for next mods? I was thinking of getting NST pulleys. Would love to swap out the gears but I have a feeling labor will be a couple G's

I definitely recommend the pulleys. It improves power throughout the rpm range. On that same note, a new flywheel would prove worthwhile as well. But I wouldn't get it unless the clutch goes out, or your getting an upgrade.

Yeah I thought about a flywheel but probably wont get one any time soon. Are pulleys the last power mod left? (Excluding headers since they don't do anything for our cars)

Always go with headers and the new Jun cams

Curious...how much did those gains cost?

Nice gains.

Screw all those ones being recommended ... Get some new gears .... Best mod I have ever done ...

^^^

+1

OP what are your goals?

Those are very nice Numbers SAE corrected

M370: $450
Intakes: $425
Cats: $580ish? Forgot exactly
Install and Uprev tune: $1300

Didn't include the cost of the exhaust since it was already part of the baseline

Goals are to go faster when I hit the gas lol. But it's my DD and has not seen the track ever so nothing track-only oriented as far as mods. Like I mentioned earlier gears would be awesome but Idk if I wanna pay for the install cost




Still waiting on Zuperman to install his so I can see what the gains are like lol. But idk if he is still planning on doing it. Is there another member that has installed the Jun cams? How many hours of labor would I be looking at?

So these number include an UpRev tune? I would have expect more with a nice tune on top of all that stuff.

Yeah this is with the tune. Notice how my peak hp starts to drop off on the upper line. I'm thinking this is due to the M370 because I have seen similar graphs posted here from people with the M370. It loses power at the very top of the rpm range but adds power in the midrange. I think without the M370 I would have had higher peak numbers

Ah, that makes sense.

So did you do an actual dyno tune at an UpRev dealer or was this one of their etunes?

Just curious. You certainly can't complain about 314 rwhp. :)

I'm not a fan of altering engine harmonics.

Dyno tuned at Z1 Motorsports. Got the baseline then had the parts installed and dyno tuned right after.

Ok, good to know. Z1 is awesome!

Since when was the stock pulley a harmonic balancer? Looks like a pulley to me, albeit a heavy one. Oh wait, it has a rubber band...

Back on topic, if you had the funds and willpower, headers will definitely give you a boost in power, I would say 10whp or more on your setup.

wow you were running pretty lean before the tune (if I'm reading it correctly).. bet it feels a lot stronger now

You think so? I have only seen a few dyno graphs for headers but none of them looked like there was any notable power difference at all. I am talking about shorty headers and not long tubes of course

I noticed most of the power after 5k rpm and a definite jump over 6000. I might even bet that if you adjust you rev limiter to 8k, you might make power all the way there. I was still making power at 7500 rpm and I'm running with no tune. (fixing O2 sensor tomorrow) I'll be getting a tune done soon though... Definitely before I leave again.

i love my headers they make great power!

i to am running out of ways to add power while staying NA

dont you have longtube headers though? Not really the same as shorty headers. Maybe I'm confusing you with someone else but I thought you posted somewhere that you have longtubes.




Which headers do you have?

Did you install the m370 yourself? How hard do you think it is to install without a shop?

No I didn't do any of the install myself so I can't really answer your question. Maybe someone else will chime in

I've been thinking about adding this mod myself, but I was reading some other threads that some guys lost Hp? thats the last thing im trying to do, but from my understanding its a direct bolt on so I dont think it would be too dificult.

You will lose hp at the top end but gain hp and torque throughout the midrange. You can see this on my dyno graph...power levels off then drops slightly after 7000 rpm

Pretty sure you need a tune though otherwise you will lose power with this mod. Someone correct me if I'm wrong

I did the install in my garage and I have no mechanical fortitude besides just knowing what's looks right and what doesn't

Get some hex keys for your socket wrench, metric deeps sockets, extender, and very basic tool set. With the hex keys on your socket wrench, you don't have to disconnect the throttle bodies from their connections. Took me a few hours, but I didn't have the right tools at first.

I do have long tubes. Shorties won't have more than a few whp gains as we already come with shorties from the factory (with a terrible looking merge collector) Stillen's shorties would help that out, but only a little bit. I have PPE LTH's. LTH's are the only real way to go if you were to do headers. Besides, they sound bad a$$ at full throttle and instantly recognizable when heard. :driving:
