We have been seeing cars with stock turbos making about 320-330 and running mid 11’s
I wasn’t saying 12.4 is the max for a stock turbo setup. :lol: Obviously cammed Evo IX’s will make a lot more power than an Evo 8 with exhaust and a tune… 
If you want to post your results, you have your forum. This one is ours.
06 WRX from today. For some reason this car only hit 12 psi on the dyno vs. 17 peak on the street so I had to roughly adjust the boost settings temporarily to do the dyno portion of the tuning. Then I set the wastegate duty cycles back to normal for the street. I’ve not had to do this on other cars so it’s a bit of a mystery.
In any case…the car behaved as expected in all other respects. Stage 2 06 WRXs have efficient heads and are higher compression than most other turbo models. Couple that with a tiny tdo4 turbo and you have a setup that makes great low end, but peters out early, causing much lower peak HP when compared to peak torque. Still, you can’t complain about making more than stock sti HP and WAY more than stock STI torque with a few basic mods. This car also has one of the cheap TMIC upgrades which will provide more consistent power delivery on the street. I didn’t crank the boost higher than I would on a stock intercooler because this car gets autoX’d and when a top mount car sits in a parking lot between runs the bigger core will hold more heat than stock.
We’ve already established that its a waste of time to compare different vehicles charts from different dynos.
Em - if you have concerns about your dyno readouts, please contact Mustang.
KTHX.
I just had our second traction issue on the dyno. This was the first for an AWD car.
Innovative Tuned Evo 8 on pump and meth at 30 psi. 549 whp, but it’s spinning. It spins real hard as it comes on boost…RPMs go up and hold…then it revs out but seems to continue spinning some all the way out. It’s a 5 speed car and I tested it in 4th gear with various strapping methods. First I tried it the way I normally strap Evos. Then I let it ride up on the roller more and tried again. I moved it up more and repeated again. Still no luck. I’m going to call Mustang tomorrow and see if they have any ideas to help it get more traction. It will have the biggest contact patch sitting between rollers I’ll try that again.
I just tried strapping it down between the rollers in the back hard and it hooked pretty well on the first pull when it was heat soaked, but then spun when I cooled the intake manifold off. The way it comes on boost makes it accelerate the rollers dramatically all at once, making it spin hard. Then it seems to continue spinning some after it settles down a bit. Oh well…it’s somewhere around 550 whp on our dyno.
That sucks that you have traction issues 
Nice numbers on the evo. What mods?
built engine, t67, usual supporting mods like injectors, front mount, clutch etc.
just curious mike… why dont you dyno the cars in 3rd gear?
I tried that first because normally I do dyno the 5 speed Evos in third. It spun badly even at 26 psi peak so I tried 4th gear from then on out. In 4th gear 26 psi held fine.
ok cool, thanks! :tup:
I just realized this evo was on pump gas claps that’s awesome.
yeah 550AWHP on a mustang dyno is awesome, on pump with a 35r is even better.
It’s actually a T67 as per the short mod list I posted above, but I’m still quite happy with it. For reference this car made 674 whp on a dynojet when I tuned it a year ago. I tested it on my dyno on the same tune. I think without spinning it would read about 560 whp on our dyno. Add 20% and you get about 674 whp.
So far 19-20% seems to be added to our AWD numbers to get Dynojet AWD numbers and 6-8% gets added to our 2WD numbers to get Dynojet 2WD numbers. This is purely an estimate, but it’s held true on the cars that have been tested on both kinds of dynos so far.
2L WRX. Stage 2 plus Perrin header. Custom tune vs. Cobb stage 2 93 map.
As you can see the custom tune gained a ton of HP and torque everywhere. The best part was up top where peak HP is made the boost on my map is the same or slightly lower than what the car ran on the Cobb tune, and I still made way more power.
You never know how a car is going to run on a canned (off the shelf) map. This is one of those cars that benefited in a huge way from custom tuning.
Chris’s 05 STI. We’ve posted some graphs from this before. Today we put in an HKS DLI setup and brought the boost up to 27-28 psi on C16 fuel.
I’m really happy with this one. The customer wanted more power everywhere with as little loss of low end power as possible in a reliable pump gas package that passes inspection. I’d say we nailed that. It has double stock power in one area and under 3500 it barely lost any power because the car spools up so well.
damn thats a good lookin ka-t
