Because one person posts a dyno with bad results doesnt mean all Fits cant gain power.


Uhh.... That could be the problem here.
Another thing could be the dyno being out of calibration. Everyone remember that 110+ WHP Fit with like an intake?

*LAUGHS!*

Sugarphreak, get it re-dynoed somewhere else. See what happens.

As for the 1/4 times. My Fit ran a 16.7@81mph with an intake and a muffler. A 2.3 60 foot.

 

if ur car is feeling much faster than a stock fit then u probably got a wrong readingor something...theres just no way

 

I was looking to avoid the calibration issues with this one, everything here was measured on the same yard stick so something is up with the car.

We ran my Fit & ET's Fit back to back to ensure the calibration was good. YeeFit's Fit was also on this dyno. Everything came back good except my results. (Will let YeeFit post his own).

Tires could have impacted the results... but this was bad. Even if I gain 5whp somehow on technicalities I would still be pretty disappointed.

True, would be happy with 12whp at this point though!

The tune is definitely the prime suspect here unless the parts are somehow having a negative affect on eachother.

 

Maybe its the fact its a Mustang dyno. They do give results lower than other dynos.
My Mazda did 211whp and 287ftlbs on 13psi and the old T3. They said on another dyno it was good for 220-230whp.

Id still try another dyno.
How does the car pull compared to other Fits? Mine pulls damn nice compared to the few Fits Ive drove.

 

I think I read that the Mustang Dyno's are usually off, can somebody confirm that?

 

Seems to pull nicely into the upper RPM's, but for sure I have given up some below about 3000rpm. I always suspected that much anyway.

I am out of time though for now; need to rework things and see if I can't turn these results around in November. Because we ran a stock fit as well I suspect that we would get the same kind of results at another dyno. Has to be a technical problem or maybe defective product.

They do read lower, but we had a stock fit that was used as the baseline. Basically if you were to dynojet at sea level the stock fit would read something like 92 and mine would read 94.

Without a baseline or control the results would have been questionable. These are conclusive (assuming ET's stock Fit isn't a freak that produces more power than it should)

 

This is so sad to read, but I hope you find out what's causing the problem soon.

 

My guess is your tune is running pig rich and loosing HP. Also how come you did not have the dyno shop put a tailpipe sniffer up the muffler, and get a idea what the A/F was for $200 they should at least have done that. My local dyno only charges $60 to run a test and that includes checking the A/F When you originally had the tune done, did they check the A/F then? Also Mustang Dyno's are usually considered more accurate, and that's why they tend to read lower. But if your friends stock Fit put down almost the same numbers, its not the dyno.

 

I would even settle for having a discernible problem right about now, the car shows no signs of running too rich or lean.... nothing seems to be malfunctioning.

 

Well it was a pretty shocking dyno run for Sugarphreak.. I will admit that.

But it is true to say that the only way to pull out some good numbers out of a 1.5L econobox motor is to go the forced induction route.

Everyone who is dissing the 1/4 times for us up here needs to understand that there are many other limiting factors, most importantly the elevation. We are 3500ft above sea level, and for most this will equate to almost a 1 second slower 1/4 time. So, if someone were to run a 17.2s 1/4 mile here, it would be 16.2s in a place like Vancouver or Los Angeles.

I don't feel like starting a new thread for my dyno results, I have still yet to get my car properly tuned and setup. Once I have that done I'll start a new thread and hopefully be running 8-9psi. I was running a bit rich out of the boost range and a little lean when the boost came on.

So here are my mods and my results:

YeeFit Main Performance Mods:

• T1R Type-S Turbo Kit @ 6psi
• T1R Test Pipe
• T1R B-Pipe
• Greddy Ti-C Axleback
• 15" Enkei RPF-1

YeeFit Dyno Results:

• Max Wheel HP - 154.9 @ 6100 RPM
• Max Wheel TQ - 146.3 @ 4900 RPM

Once again, we are 3500ft above sea level and we using a mustang dyno which can equal ~10% loss over Dynojet results. So I was pretty pleased with my numbers to say the least.

After tuning and a few other little mods to get things running smoother, I hope to gain around an additional 20-30whp

 

My guess would be the tune. lol I have a wideband if you wanna buy it!

 

Nice numbers Yee... And yes, the T1R kit does run lean. Thats one thing I dont like.
Of course if I got it Id have it re-tuned ASAP. Cheap insurance with FI.
When you up the boost to 8-9psi be careful as it seems the OEM pump is limited to 9+psi.

This hasnt been proven but if Ben was having problems with detonating at higher boost the last fuel component is the pump.

Again, nice numbers man.

 

*cough* Supercharger *cough*

 

Hey, don't you have one for sale Illusive?

 

theres your problem....$200 dallor tune....cheapest tune ive ever seen....i charge $165 an hour and use a dynojet 248h....most tunes avg around $600....i would bet money the "tuner" isnt really a tuner....
if you can...download the fuel/timing maps out of the emanage and send them to me.

 

i think if you
-installed a test pipe
-lighter wheels
-tune on a dynojet/dynapack

you would see the numbers you are trying to achieve. other factors could have been involved like a slipping clutch. just dont get discouraged man.

 

It's very sad!!
I suggest you to don't use E-manage ecc ecc..
In my opinion you have only to raise your fuel pressure to +0.3 bar, reset your ecu and run 300 km before getting it re-dynoed....
Don't worry about your results.. you'll certainly get better!

 

wow im sorry dude.. im going for a dyno run too on the 21rst i cant wait to see my numbers

 

Wow.... $2000 for 2HP

pwned

 

Trying to not let this get me down right now, will take another stab at it laster on.
