yfz450r dyno

[transam97]

Just got me a fci an a gt thunder ecu. Going to the dyno fri just wondering what everyone thinks my gains will be? It already had a k&n an a pc3 an made 42hp an 27tq.

[funyun]

Maybe 2hp? Are you going back to the same place? Does the place you're going know how to mess with the gtthunder ECU

[transam97]

Yea Im gong back to the same place. An yea they know how to tune the gt thunder ecu.

If your going to run the FCI with a box, then your gain would be very minimal from my experience. If you run the FCI without the box, you could see up to a hp increase. I don't know how much the gt thunder ecu will add, it will be an interesting test. I wish you could have done it on the same day though. Who knows what the dyno is going to read at a different time and date. I switched out all my parts on the dyno so I could get the most accurate comparison possible.

it should read very close as long as you use the same tires. In all the dynoing i have done we get very little variation when we test stuff even months apart (less than a HP). Using different tires has given us a larger variation (2-3hp). I heaver tire makes less HP since it adds rotating mass.

what pipe are you using?
I would bet that gtt ecu will give ya a nice increase, alot better than
the piggyback fuel controllers.....FROM MY EXPERIENCE

[transam97]

Im running a full yushi pipe. An I did the 06 cam to. I was just hoping to get up to about 30 or so tq an 45 hp.

[bbcmudtruck]

I hit 44.5 without the 06 cam. I think you could hit 45.

[transam97]

How much tq is yours putting out?

[funyun]

Curious how the gtthunder Ecu could give any more power than an msd. What made you decide on the ecu instead of an msd

[transam97]

I just heard there is a lot more tuning capabilities with the gtthunder then the msd.

[transam97]

Just got back from the dyno made 45.82 an 29.66 tq...

[funyun]

Not bad, 3hp from the fci, 06 cam and gtthunder ecu. Any pics of the graph?

[transam97]

I have one but I don't know how to post pics.

I'd like to see the curve as well. I'm wondering if the bottom end hp changed any or if you just picked it up on the top with that cam?

[transam97]

I'll try an get some uploaded later today.
