Dyno graphs from tonight

[MPFab]

Put the Sonic back on the dyno tonight. I'm currently developing parts that I intend to sell, and have been doing a good bit of testing at each stage. All of the parts are prototypes at the moment, and I'm not sure if I'll offer all of them yet.
Currents mods:
Intake system
Aluminum intercooler hard pipes
Ported intake manifold
3" 304SS catless downpipe.
3" 304SS midpipe with 100cel catalytic converter
3" 304SS cat-back with two magnaflow mufflers
Trifecta "Full" tune right outta the box
93octane

The car was run on my the local Mustang Dyno. This dyno reads 8% LESS than the typicall DJ dyno. I have verified this on a local DJ dyno a couple months ago. I intend to put it back on another local DJ again for direct comparison.
WHP = Blue
WTQ = Black
AFR = Red
BOOST = Green

These numbers work out to 188whp and 231wtq on the local DJ I've used for comparison.

Based on the last couple times I put the car on the dyno, it appears I'm at some sort of ECU imposed HP limit past 4750rpm. If I overlay this graph with the last time I was there 6wks ago pre-3" cat-back (stk cat-back) I found HP and TQ to be virtually the same from 4750 up. I would presume this is a "safety net" that Trifecta has enabled to keep some part of the drivetrain happy or keep the injectors from going static.

Power on this dyno when the car was 100% stk was 120whp and 129wtq. The graphs posted below are with the airbox lid open(+6whp/wtq). I meant to grab the 100%stk graph for comparison, but mistakingly grabbed these instead. Either way you can see how dramatically different the midrange is.




Now to figure out what needs to happen in order to raise the upper RPM power limit so power can keep climbing!

Nice! That's really good numbers out of this engine, especially the torque. I'm at 215tq according to GM PID's and that's only crank HP, I think you'll have alot of people asking for some goodies.

I like how you list alot of conditions about you're run and current mods... That's very telling of an honrable person in my book.

If you wouldn't mind could you drop these graphs in my new dyno thread. I've actually got a link in there to an old thread you posted in and then disappeared claiming you found the holy grail only to never return.... Ok i exaggerated the last part but you were working on something lol.

Oh and what's your "trade secret" mod? there's more than just what you got listed, I know there is haha. It's safe to assume you're a tinkerer and I know those WHP WTQ aren't just bolt on goodies and a tune. What's the ace in the hole?

I can honestly say that what is listed is ALL that is done to the car. I'm a fabricator, and I build this kind of stuff everyday.
I definately have a process and set of rules that I follow when developing parts. The guidelines I use have worked really well for me over the yrs. and have often allowed me to make more power with less.
I appreciate your scepticsm. That feels like a compliment so thanks!

 

[sx sonic]

It was a compliment haha, good stuff.

edit: nevermind. read too fast

Its nice to see people doing dyno pulls. With all the mods coming out its the only true way to determine which mods are worth it without going to the track. Nice numbers!

The boost dropping after mid-range may be due to the WG also being partly managed electrically.

For trifecta to make boost go from stock 14 to tuned 22 without physically changing the actuator tension, probably requires him to trick some of the ECU's feed backs.


He can demand more airflow via boost earlier in the curve, but the ECU can't be tricked when other sensors are warning it about the aggressive engine behavior.
^^^^^^^purely speculation^^^^^^

A mechanical boost controller might get you around that obstacle.opcorn:

From looking at the HP logs, the boost control solenoid it at its max value were the boost is falling off. Either the turbo is done or I've got a leak somewhere. Given the power it made, I'd be surprised if it is a leak. Most likely the turbo is kaput!

Ahhhh. That makes the most sense. And not surprising. If you use standard sizing formulas, I'm surprised the stock "gt14" is even getting over 200 chp.

Intake tumblers choking off top end? Mine gained a lot of top end by porting the composite intake.

I ported the intake already. That plus hard I/C pipes picked up 11 ponies.

 

[Graham]

Right on, mine was a different animal after porting the intake. Sounds like u need a bigger turbo so do I..

Don't we all.

 

[Graham]

Do you have a dyno graph showing the gain from tuned to tuned with ported intake? I'm curious to see what the curve does before and after.

How is the driveability with the intake ported? Does it still have strong low and mid range.And does it loose any fuel mileage.

Fuel mileage is same, and no loss of low end or mid power. I had a tune already, so results could vary if you're on the stk flash.

 

[BoostedSnail]

you gained 11 ponies with hard pipes?

Ported intake manifold plus hard pipes yielded 11whp

 

[BoostedSnail]

Ok
