Dyno - stock QC

or as stock as one would be with a K&N CAI on it

The dyno was both a happy time and sad one. I was looking forward to running my truck with the K&N CAI and DC II flash, but on the first pull Sean aborted the run as the engine was ticking like a Grandfather clock. That was running the best gas I know to buy BP/Amoco Supreme 93. Being that I carry the stock PCM with me, we plugged that back in and I had two full pulls with the CAI and stock everything else. So since I do not have the stock air box set up anymore I couldn't get a true base, but everyone seems to think that CAI does nothing so here are the numbers for those stock pulls:

pull 1 - aborted - time 10:51 AM
pull 2 - HP 451.30 TQ 468.76 - time 11:03 AM
pull 3 - HP 447.79 TQ 470.19 - time 11:04 AM

So the time to hook up the stock computer was the only delay in the back to back to back pulls, but the truck was running good.

Now I will say this - the run that was aborted with the DC II, was on it's way to seeing better numbers, but nowhere near 70HP and 100TQ better, but those are my stock numbers

There is no way a stock, meaning only CAI QC should be putting those types of numbers down. Those are VERY good numbers and would likely be the highest I've seen for a stock QC. You can see my numbers in the signature. Roe did the pull before yanking the motor out of my truck. You basically got the same numbers without headers, exhaust and computer upgrades. Seems odd.

Call Sean - those are on a stock QC only upgrade is the K&N CAI

Trust me on this the other Silver QC that dynoed just after me, then one that tried the SSB filter was almost 25HP and 30TQ lower then mine was and that was 30 minutes later

That's why I am so stoked to get the High Flow Cats and do that second cat delete - they said that is good for anywhere between 10-17 HP

hell - ask anyone that was there and read the Dyno computer - Nothingbuttrouble, john holmes, Sean Roe, Dave at Roe, there were like 8 of us there.

And that was on the Stock computer - as I said before the DC II was pulled (unhooked) after the first attempt.

Are you running the DC Stage 2 without the 172 tstat? That might explain some of the ticking....

D

No I am not, and there is no way that explains any of the ticking, 30 something degrees of timing in that RPM range explained all the ticking.

It's actually pretty easy to explain. The silver paint is worth at least 25 hp. :eek:

:D

Are those numbers SAE corrected...?

The DC flash gives you 70ish more hp at lower rpms not peak hp.....

I believe your numbers, but those are crazy high numbers for a stock QC. I hit 438 RWHP and 500 TRQ with stage 2, K&N and Borla with rear cat delete. Sounds like you got a real great truck there.

No I am not, and there is no way that explains any of the ticking, 30 something degrees of timing in that RPM range explained all the ticking.Well, perhaps not. :confused: Just trying to help, since I remembered DC recommending the 172 tstat (http://www.srt10forum.com/forums/showthread.php?t=7930) with their 93 Stage 2 flash....

D

Those are the correct numbers. I was there at the pull and saw the graph immediately after the pull. Very good pull on his truck the way it is modified.

It was a very cool day, probably the best conditions for a dyno in Florida as could be expected.

The ticking is something else, not the thermostat. His engine temp was below 170 during the pull. They actually warmed his engine up a bit for the pull.

Turned every ones head the noise was so noticeable.....SAE corrected #'s

Wow, those are incredible numbers! ;)

Typical stock QC's were putting down 405-425RWHP.

Looks like that CAI gave you 20-30 RWHP :D

Gotta be happy winning the strong motor / good tranny lottery :cool:

I didn't mean to come off the way I did. Just amazing that the numbers would vary so much. Awesome for you!!!.

Hell when I did my original dyno with just magnaflow's I was at 380hp, it was HORRIBLE. My a/f was totally fvcked up. That is why I had to tear the whole thing down and start new again haha.

I do not think for 1 second the CAI has that much power on it's best day. I do think there is something to them just from the smooth tube keeping the air from getting dirty, that's all.

I do think that yes the truck has a great combo - sometimes you get lucky and one powertrain package works better then the identical one on another truck. That has a lot to do with these numbers, but the numbers don't lie and they were really strong.

You didn't at all and my response wasn't meant to jump on you if it seemed that way sorry - what I was trying to say is there were 8 others there and none of us could believe what that CAI and stock combo put down - then back to back at that!

Hell I was hoping that the DC II would put some big numbers down on top of that, but tick tick tick and abort!

We did run the DC II up to like 4000 before he shut down the run, and even down low the gains were no where near 70/100

that's where the disappointment set in, then I realized my truck on the stock computer just layed down the largest numbers I've seen on the forum and that brought a smile to my face that I still haven't erased.

I am truly looking forward to getting the exhaust combo I mentioned in the other thread from Roe and running it again.

Besides who can argue with that modified drain plug picture that it's worth 10-15HP now, I've got the numbers to prove it! HA HA!

It does seem that the truck is putting down some amazing numbers, but I swear this is a true as anything just the CAI and nothing.

What's nice is it happens to be Silver and we know that means something now!

I was joking about the CAI :)


You have witnesses and believe you, would bet you didnt get more than 5-8rwhp from the CAI.

Lucky bastage :D

Well, the weather being that cool and your engine temp at 170 degrees would explain the difference in power. I dyno my QC with the same K&N CAI and got 421 RWHP and 442 RWTQ. The temp was 73 degrees and engine oil temp was 205 F. I wanted full heat soak to get a more day to day number.

His dyno is SAE corrected. :rolleyes:

Alright, so so you are relying on the software to do the correction? I wouldn't. If you want proof, do your dyno on a cold day and then a warm day. I bet your dyno will be completely different even with sae correction. It's really bad when the temp change is pretty drastic. The software correction sucks...

Maybe I'm going to need to do a road trip and have Sean take a look at my truck,and maybe get some better numbers out of it!!!I'm not impressed with the BG PCM!The only number with the flash that I liked was the 464 Torque.HP went from 407 to 411.Not enough to make it worth the $800!!

take it to the track. every dyno is different :-P

dyno's are useful for showing how much gain/loss you get from making a change, and for tuning WOT. that's about it.

That's one of my biggest complaints,I went to the track,and couldn't beat my best stock time!!

6 pack get in touch with Sean at Roe or Macedo motorsports, sounds like you need a dyno session to sort your ride out.

You guys aren't taking into consideration that all Dynos pull different numbers. I bet if you put another stock SRT on it it would read the same....I dynoed my 04 sti, on one dyno it made 338 to the wheels and on another it made 369 at the wheels....no changes, even same air temp/conditions....so go figure.

that was the point of my post - we rolled another stock QC up right after mine - Silver (so it should have been the same) only differences in the trucks mine has the CAI from K&N, his had the Magnaflow Cat back, he rolled off around 425HP and 450TQ, these were done about 20 minutes apart from eachother, so air temp was the same and everything. His numbers were in line with what we see from stock QC

There were plenty of us there for sure.
Jamie...you put on the exhaust yet?

Is the DC Stage 2 and the B&G flash the same thing?

I do not know, but I'm with 6pack on this one, I haven't seen that HUGE jump in HP and TQ numbers that are claimed.

I may not have expected 70/100 as claimed, as that may have been on a modified truck or something, but I have the dyno run up to 4200 before we shut it down and down low where the flash is supposed to make all it's power it was no where near 70/100.

Apparantly the flashes are all from B&G but Boomer, DC and B&G each have their own twists on it.

I think B&G only offers a Stage 1 upgrade, Boomer and DC offer something more aggressive like a Stage 2 from what I remember early on in the computer offerings that is what was discussed.
