swung by autowave for a quick dyno 349.3

349.3

My last 2 runs were at 326 with a k&n short ram intake and 336 with an oem airbox a comptech filter with the oem cats on it.

I was told to put the oe box back on and get a tt exhaust should get me closer to 360? I am still miffed at the numbers, but it drives well.

Matt,

Looking better everytime, your #s are increasing each time. 349.3rwhp is easily 400bhp, 2 more dyno session you will hit 370rwhp.

If your original baseline is 260rwhp. The gain is phenomenal (+89rwhp), but if your baseline is 290rwhp+ like some Steve or Vance. Then the gain is mediocre (+59rwhp), a more free flowing exhaust will definitely help.

Comptech's dyno shown 109rwhp gain over stock with addition of CTSC/I/H/E.

I am going to redyno my as well, both at Autowave and Dynoextreme in late January after my next power adder mod.

not to be an idiot...but doesnt he have the CT h/e...and basically the same I.....how is a MORE freeflowing system going to help any more? he doesnt even have cats !!!....seems like he has the same setup as CT does for thier dyno pull...
i would be someone miffed also...i am sure youll find out why they seem low...but i am in agreement with matt......

 

[nsxsupra]

how is a MORE freeflowing system going to help any more?

so far every time Matt made a little change, the power went up. Try another exhaust + putting the oem air box back on doesn't hurt. Don't quote me on this, more free flowing=more power, no?

he doesnt even have cats .....

So in theory other than sound and weight reduction, aftermaket exhaust is useless, if you run oem exhaust without catalystic converters?

 

[The Kid]

Are we talking test pipes with a stock exhaust here? If so then that number is understandable....I picked up alot of HP when I switched to a CT exhaust/header. I think I dyno'd 300ish with my exhaust and some cracked DC sport headers. Then after the install and some minor tweaking I was at 342:biggrin: Test Pipes dont do shit but make your car smell bad and sound loud:wink:

 

[01blacks4]

no supra.... i did not mean that a free flowing exhaust will not help, we all know that it will....

you made the comment that he will make more power with a free flowing exhaust, yet he already has one, and has even ran the car with this exhust and no cats....cant get much mor free flowing than that so i was questioning what you where eluding to with your comment that "a more free flowing exhust will definatly help"....

i cant see how it will, especially if you are using the Comptech dyno as an indicator for a guestimation of power, and he states that he is using the comptech headers and exhaust already..


sorry if i caused some confusion..

after reading the kids post,
am i the only one who is reading that he already has the competch headers and exhaust?

I second that notion about the test pipes. I believe I saw only about a 2hp gain, which is pretty much nothing when you consider variability between runs.

I missed it, why the numbers so low then?

He must have that dyno setup to read like a DynoJet, there is no way a stock car that is rated at 290 will put down 260 on a DynoDynam ever. I guess he set it up that way so people can have big #'s to talk about On a DynoDynam that is not set to read that I put down 320whp on a dynojet that would be around 380-400 whp, just to show the difference.

Agreed. On my previous car, Evo, I put down 380awhp on a dynojet. When I went to Dyno4mance and got on a DD dyno, I only put down 330awhp. For some odd reason the DD dyno's out there in Cali are setup to read high like dynojets. I am not saying that they are incorrect readings. But, they are just setup to read high.

Thanks,
Nathan

Mike (Autowave) did my tune on my DynoJet. We got 360WHP out of it. Probably could have gotten more, but I'm happy with the results because it drives nice!

I don't think Autowave's dyno is reading wrong because pierceman would be at the other end of the spectrum vs all of the other dyno charts we've seen coming out of there.

Here is a real stupid question for you Matt. Is your SC belt on there tight enough?
I got mine dyno'd like 2 weeks after I got my SC installed and it read 343 rwhp.
Then I re-dyno'd it like a month ago (my mechanic had mentioned that my belt was loose like 3 months before when he installed my gauges etc.)

Here is my chart:

Nathan,

All DD dynos have a correction factor to bring it in line with the more popular/ abundant Dynojet dynos. On the eve of USCC, we got 650 rwhp at Autowave's DD dyno; we got 677 rwhp on the first day of USCC on K&N's Dynojet dyno. At the very least (it was cooler at Autowave: night time in H.B. vs. day time in Riverside), this comes out to about 4% underestimate on the Autowave DD dyno.

Regards,

Danny

I'll re check the belt. I have comptech sc, headers and exhaust. With cats in and stock intake box and unifilter I was at 336 now with test pipes and arc intake I was at 349.xx

 

[sjs]

Matt,

The belt may have been part of it, but ambient conditions may have been also. My experience if that correction factors are not nearly as good as they should be, so the difference between a mid-August afternoon and a November morning can easily be 20HP even after corrections. I’ve seen seven on a Spec Miata engine making a whopping 110 at the wheels. So don't be too disappointed if it seems to drop again next summer.

^:wink: Got ya. I'm not too worried, just having some fun internet talk when I wish I was out driving VIVA NSX!
