Ya, I wouldn't worry too much about dyno numbers at this point. Get some 60-130s. That will tell the story.

 

agreed.

 

My car made 499 AWHP on a Mustang here in MPLS. Hot day (95 in dyno room) with
one fan on the back of the car. 1.34 bar

134.6 trap
6.4 to 6.9 60-130

dynos can be decieving

 

Out of curiosity, how many fans did they use and where were they located?

 

One big fan on the back side right in the middle. No fans for the intercoolers !..maybe that's the issue. And my max boost was 1.2 bar.

 

Welcome to the wonderful world of dynos. Dont get too caught up in the fact that your car made different power on different dynos. This will happen....even on the same dyno on different days.

A few notes... The DD you dynoed on it the highest reading DD I have ever seen. Your dynojet number were about what I would expect.

You mentioned in your email that the car made 475hp, why post a lower number here...cofused.

" 475 HP and 470 TQ on the final pull after some cool down."

All and all, I wouldnt expect much more power from a 1.2 bar 18g car on pump gas, with stock ics.

For reference, John D's car (also an 18g car) made 490 @ 1.2 bar on our dyno, with upgraded IC's, y pipe, plenum, throttle body.....

 

No intercooler fans? Seriously? Wow.

Im surprised you made the numbers you did...

 

Tony, I did not get the 475 hp sheet yet from the dyno place. I will email that as well.

So what can be done to get more power? or what could be wrong?

 

It was too late ...by the time i got there ..they already did 4 pulls.

 

what can be done ? well first off take it somewhere that knows how to properly dyno porsches , you need the rear bumper off and fans on the intercoolers .

btw where was the car taken to get dyno'd ?

 

This was the nearest mustang awd dyno. They are great people to work with , but have no porsche experience..

Benchmark Tuning ...they do mostly subarus,srt etc...

Talked to Tony , everything looks good from an A/F standpoint, i will try to get a v box and do some runs soon and re dyno with fans when i get a chance. Can someone here loan me a v box?

 

You NEED fans on the I/Cs. I usually blow fans into both I/C ducts from front to back, but I've always had the Proto intake system.

FWIW, I made 580 rwhp on a Dyno-Dynamics with fans at 1.3 BAR on my 18G setup, and then made 600 rwhp on a Dynojet without fans a few days later. The car trapped 136 at that level.

 

Thanks. There were no fans on the intercooler and the only big fan wasnt doing a great job either.

I am going to run some 60-130 #'s as soon as i can get a V box.

 

60-130 is all you need, V. You'll make 426hp on that same dyno next week!!! You're all tuned, that's all the dyno is for. With your mods at 1.2bar you should be mid 6's easy, if not, it's not the car.

 

I learned this lesson last year too when an EVOMS GT660 996TT and myself (EVOMS stage 2 at the time) went to a dyno locally that had no experience with P-cars... and I hit like 320whp and the 660 car hit like 380whp. LOL.

We told them that ain't right and they were just saying and thinking our cars didn't make the power we thought. Good times!
