so if I have just a muffler delete with my 09 balt ss what kind of relaistic numbers will I be getting with trifecta tune, at the wheel and at the crank? average numbers

 

Original tune or the new Extra Krispy one?

 

the new one

 

prolly like 323whp and 400 wtq

 

probably hovering around 300whp, 330lbft at wheels

 

Probably about that. This car can make and has made over 400 wrtq on the stock turbo ( ZZP made 411 wrtq with a MBC and tune) but the safest most reliable thing is to run the car at no more than 24 psi with will create 360-390 wtrq and anywhere from 300-325 whp normally.

 

so there is now an extra krispy trifecta tune? sounds delicious. i can't wait to order one of these things... my main concern is... needing a new clutch. that would sooo not be good lol.

 

I am on stock clutch still, Even with the slicks the only time it has slipped was a tried launch at 5500 rpms. I dont advise that on the stocker.

 

good lord why'd u launch at 5500? gettin off the ground lol... oh sorreh these ain't rear wheel. i wanna do boltons after i tune then retune after... but i think a tune first will satisfy my cravings so when i have money to just throw away i'll upgrade the plastics instead of trying to save money just for that lol. plus i want the thing to appear completely stock so when i rape gt's and d bags around here with loud junky looking cars they feel worse they got whooped by a cobalt i luv this lil car glad i got it.

is the aggressive tune more expensive or the same price?

 

Just dyno'd the new trifecta tune... you are looking at 255whp (4400 rpm) and 318 tq (4000 rpm)... Mine was done at a 4200' elevation, 81 degrees, low humidity....

Here is the sheet:

 

that doesnt sound right, high elevation tho

 

yuh that's kinda a turn off lol. i wonder what stock woulda been.

 

I don't have dyno numbers yet, but I can give you some real world comparisons...

I installed my Trifecta Switchable Tune on Friday night and ran at a charity run what you brung top speed only drag... IN THE RAIN. I ran 100mph in the quarter and tied with an SMG tuned SS/TC. We both had crap tons of wheel spin through first and second due to the wet conditions. We were the fastest front wheel drives there, and 3rd fastest overall, beat out by 2 eclipses who where awd and ran 104 and 102.

The SMG tuned balt's dyno numbers: 293whp, 320wtq....

There are lots of factors that could have affected our speed, but that gives you an idea. The closest car to us was a modded scion tc that ran 98mph.

 

that 4200ft definetly has an impact on numbers, still good torque represented. Stock at that altitude id expect somewhere in the 210-220whp range (unless the ECU compensates for the drop in density altitude)

Im at roughly 700ft elevation, and the car is a handful with roll on 2nd gear burnouts and abundant torque steer. My superchips tune is probably 270-280whp and is significantly less potent than the new trifecta tune.The low end and topend are much more substantial.

 

Is that AFR accurate? That is where your power is goin out the window.

 

Didn't have a AFR running on the car.... and guys try to keep in mind that this was done on a dynomite dyno... not a dynojet dyno or mustang dyno....

These numbers are actually very good (flame on if you must)..... A stg2+ STI dyno'd at cobb puts down 265whp...(I have that sheet if you want to see the comparison)... so a ss/tc with mods and tune is going to put down 300+whp??? Not hardly (sorry to be harsh)... In comparing the performance of my cobalt to the stg 2+ sti what I have noticed is that the cobalt has a much stronger launch (if you can stick it) but over all the sti is slightly faster (very slight though)...


Keep in mind that a 14.6s 1/4 mile car at 3200lbs (roughly weight of cobalt + fuel + driver) is only about 203 whp (calculated)

for 13.9s you are looking at 235whp (calculated)

for 12.9s you are looking at 294whp (calculated)

Basically the car will run comparable to a stg2+ sti (not bad in my book)... now if you can overcome their advantage of having awd is another story.... (Keep in mind also that a 2+ sti is basically a stage 2 with turbo inlet, lightened pulley, sri and custom dyno tune... and my 'modded' cobalt is a cai, charge pipes, dp, catback, and tune).....

ok...now I am going to sit back and enjoy the show....

 

different dynos, different elevation, different drivetrain.... way too many variables to compare .....

The OP should have done 2 runs stock and trifecta

 

Nakaiya21- Did u datalog the car and send it back to vince? Because when I got the first tune it was sluggish and I didnt know I should have datalogged it and sent it to vince for him to adjust it. Now I got the new tune and I have datalogged it 4 times and got 4 more customized tunes from him and each time its getting a nice bump in power.

He starts out conservative and sees what you really want and they he will get more aggressive depending on what you want and how your car performs. Each car will act differently to the tune so he is starts out on the safe side, and then he gets more aggressive once he sees how the car reacts to it. I highly suggest you do that it if you havent.

It was a very humid day and the car keep bogging off the line, so I just tried it, and did not work.

 

I wonder if that was actuially more the cars torque managment to blame for the bogging and not as much the hot weather? I know Vince raises the management parameters but sometimes they aren't raised quite high enough. Such was the case with my car, the parameters weren't raise high enough and from time to time I would get bogging due to the torque managment.. Just a thought

 

Yep, this is with data logging (went through 3 variations).... This is actually my second tune with Vince (I had the very first one put on in Feb)... The hardest part of tuning my car is incorporating the cai... tends to give Vince a fit.

The big thing to keep in mind here is that every dyno is different... some are more conservative than others.... Would I have liked to have seen 300? Sure.... Is it accurate to see 300? Eh, not sure.... The point to getting a dyno is to get a baseline for your car so that you have something to work with for your future mods - not to compare with other dyno sheets that are run on different dynos at other locations. Take it for what it is....

I am happy with the tune on the car... I think that having a car which can keep up with a stg2+ sti is saying a hell of a lot for a cobalt that is running with a stock K04 turbo.... Now once we can efficiently turbo swap then I think we will actually be getting somewhere....

 

dyno numbers are just that, dyno numbers

having a number does not make a car any faster or slower

 

Fixed. Personally I think 300+ WHP is pretty damn good on stock k04 also. When you can compare a $22000 "performance" car to a damn near $40000 PERFORMANCE car, in actual performance then you're saying a lot.

 

im lookin to get tuned, by vince what do i need to data log?

im running a 3 inch catless hahn dp, and cat back, and modded airbox with k&n. oh and should i wait for the intercooler piping, before the tune, or does it make that much of a diff.

 

I'd get the charge pipes first.. It will increase your air flow, as a result effect your tune...
