Looks fine to me honestly, I've seen the same numbers. You are not going to be anywhere near 275whp. I've never seen it done with just bolt ons.

 

i put 251hp on a dynapack.... All stock by the way

 

are u serious..?

 

dynopak dyno read the highest so dont get soo happy over those numbers. U can see it drop around10-15% once u dyno it again on a dynojet and +15% drop when u go to a DD dyno or mustang one.

Dyno # are only a tool to measure gains not how fast your car can run. Take it to the tracks and that will tell u really how fast your car really runs.

 

Seems kind of low to me...I did 245whp a long time ago with only intake and exhaust no tune

 

It's not about the WHP.

It's about the % gain you made.

As long as you made a gain, you're good to go.

Different dynos read different numbers on the SAME car, and ambient conditions are a factor as well. Correction only does so much.

 

sounds like someone needs some stickers.

 

need to go FI if your looking for substantial gains..

 

Guys - these numbers are low. I put down 258RWP and 242 TQ with no tune other than advancing the timing 2 degrees and running 94 octane gas on a MUSTANG dyno.

I know you can't compare dyno to dyno but an 06 stock 350z 6Mt put down 241 RHP that very day. The owner of the dyno said that he sees stock and near stock 6MT revups put down 238-244 pretty consistantly so I am pretty sure that my numbers are accurate. From what I have read, Mustang dynos read on average 7% lower than dynojets.

 

 

This is all useless without posting the before/after graphs. Why are we comparing strictly the peak whps here anyway, what about the rest of the power band?

To the original poster, look at the before/after graphs and compare the lines exactly, how does the low end / middle range compare? If you see average of around 10-15whp there then you're good, screw peak power.

That's like going F/I and having 500whp and think you can take down a C6Z06 putting down 460whp, peak HP is what tuners use to sell their tune/services.

 

the cause of my low dyno #'s was from a 3/4 inch plastic ball in the valve...!

no air was getting threw and it was causing the clunking sound.

havent re dynod it yet but theres a big notciable difference
