That's very good power on a Mustang dyno. There's a 2-wheel mustang dyno in my city and it breaks hearts all the time.

You would have gotten that 500lbs.ft if they had used blower on your i/c (as someone pointed out but I can't find the post anymore). You got rubbed of precious power there for sure. Because even with blowers right on the i/cs, you still don't get the airflow you'd get from driving it in 4th gear.

That's still a solid 500+hp and almost 600lbs.ft car. Must feel quick.

 

Not positive I follow on the fan on the ICs comment. If you watch the video, you can see the smaller scroll fans on the IC inlet. They setup fans on both ICs. They are smaller, but they are scroll fans that put out a lot of air.

The comment you are referring to was from Markski. I was going to respond with the above, but couldn't find it posted on the forums either. I only know it was posted because I got the email notificaiton, which had what he posted. I believe he removed it, maybe because he saw the video again and noticed the fans. Not sure.

 

This is definitely not a high reading Mustang dyno. I have had my 135i with full on dyno'd there, my stage 3 with W/M and race gas dyno'd there and have seen numerous GTRs dyno'd. Honestly it's not a huge heart breaker, but definitely not a high reading dyno.

 

Did a little more investigating regarding fans on the ICs. I think I understand what Darth and Markski meant. They were saying the fans should have been on the bumper/IC outlet side instead of the IC inlet side.

I have seen that mentioned in a few places, but not sure I follow the reasoning. Anyone know?

 

Nice Package,
Those are good numbers on that dyno for only being 16s..
Enjoy.

 

What would be the hp at the crank? I am also curious about the IPD plenum.

 

Next time put fans on your I/C's, your tune is super rich right after your torque peak which most likely why you did not break 500ft lbs. How did you log afr's? obd2? I did not see a sniffer in the tail pipe. Just about everyone uses 3rd gear until you start making 6-700 wheel. Damn that car was just hanging in the top end, I hate that! seems to be where 90% of problems happen.. Sort the tune and get air over the I/C's and your will pick up more power. Future mods planed?

 

Thanks for the info. But again, what do you mean by get fans on the ICs. There are scroll fans on each IC on the inlets (not on the bumper/outlets).

AFR is measured with the sniffer. There is a large black pipe in the left tail pipe.

Can you explain what you mean the car was hanging in the top end?

 

I would try to simulate the car moving as much as possible. Thus, I would place fans at each side vent to stream air to the ICs. This is what's occurring when the car is in motion traveling at high speeds. Lower speeds would have a disproportionate amount of air flowing to the ICs, so you would need to factor this in.


***UPDATE***: Went back and watched the video again, as he says above, he has scroll type industrial fans blowing air to each intercooler inlet. Other than blowing air to the radiators, the only things you might do to simulate airflow further would be to have air blown over the deck-lid (not easy to do) and have fans blowing towards the lower bumper IC outlets to simulate air removing heat from the ICs.


As the air volume can't be exactly what you would incur at speed, no dyno result will be perfectly accurate and they're not intended to be.

 

Think that's what he's talkin about. Heavy duty fans pointing up (backwards) on the intercoolers.

When I watched the dyno, it took forever to end, in that 4th gear is way too long for your power it was almost like it was stuck trying to get to the end.

 

FWIW - I had a GIAC tune which ran extremely rich... almost verbatim like yours does... not a good thing in the long run for mileage or safety IMHO

The car wants to dump in so much fuel here... I'll bet if you log injection times you will show DC% way over 100% (like my car did)... get some new injectors and get Tim to give you a Eurodyne tune... much quicker, better usability and safer

My $0.02

 

Nice numbers. Why not go higher boost?

 

Exactly my thoughts. His HP numbers likely would've been quite a bit stronger had the car been tested properly. We don't turn off intake temperature safeties which will skew HP numbers down if the intercoolers aren't properly cooled.

 

Please watch the video again. As mentioned there are scroll fans on each of the intercooler inlets.

 

I think everyone is saying to put the fans at the back of the car, near the intercooler 'exits' because the distance (to the intercooler fins) is much much shorter than the distance the air had to travel in your video... In your video, you are pushing air a few feet through the (open) air, then into the inlet-ducting of your car, it has to travel up over the wheel-well and down through the intercoolers... that's a hike for what is really some relatively 'uncontrolled' airflow...

I think that's what everyone is getting at...
