The only thing I'd be worried about is drivability going down with custom cams. And theres fuel economy, but if your ONLY goal is performance.......i guess you have the wrong car lol. I mean I wanna see someone try it and work out the size specs so go for it...
Im sure if you dont go too big it wount be bad.
Im sure if you dont go too big it wount be bad.^^ See, I'm just not sold on the Type S cams. I understand they will give us some power, but is it worth it? I feel like an aftermarket cam will give us close to double the power of the TL-s cams. I mean, from the base TL to the Type S is 28hp...it's an extra 0.3L...how much more aggressive could the cams be? For an extra 0.3L AND more aggressive cams, only 28hp? Not cuttin' it for me, sorry.
With aftermarket cams and a good tune I wouldn't be surprised to see over 25whp. It may shift the powerband up SLIGHTLY, but we should start to see gains after 3000RPM. From 3000RPM to redline, if we averaged a 10whp increase and peaking @25whp, that's a HUGE difference. It may be just me, but if you're gonna stay NA, I still think aftermarket cams will be the better choice hands down.

I don't see why they can't keep the stock or near stock small intake lobe and go crazy on the vtec lobe. If they ground it on a different LSA and gave the exhaust a little more lift, you would probably have a very nice top end pull with no loss in the low end, drivability, or emissions.

I guess that answers my question...I can't see how each dyno would vary by that much....one of the guys said to do a compression test bc he had a blown head gasket and the car still ran fine. It seems like something is wrong here and I want to figure it out

When you said “loss of power” and then said “exhaust is quieter”, I immediately thought of crushed J-pipe. Have you looked at your jpipe to see if the front down leg got smacked and collapsed?

I literally just took a look after I saw your reply, that doesn't seem to be the case. Thanks for the thoughtful response though

I doubt the car lost any power. Your numbers were extraordinarily high for a 3.2 with a couple bolt-ons on the first dyno. You used what, 3 different dynos? This is an illustration of the changes from dyno to dyno and why absolute numbers don't mean much but they're ok for comparison purposes on the same dyno under the same conditions.
The only mods that are going to show power on the dyno are the exhaust mods. The pulley, CAI, spacers, etc will show nothing on the dyno in 3rd or 4th gear

now i know that you are "the man" on the forum so i do believe what your saying. Only thing i can think of doing at this point would be do go back to my original place where i did the 269 run and see what numbers are put down. I have read in other threads that our cars put down somewhere around 230 - 235 to the wheels so thats what is really throwing me off. Last time i had dyno'ed at no limit before the 269 pull i didn't have the precats in and i made 247... to me this dyno seems to be the most consistant with my car....based on if the "stock 230 - 235" is correct.

Weather makes a huge difference. Wait for a cold dry day in the middle of winter and look up air density for that day. You can probably add another 10hp to your dyno by doing nothing. I plan on dynoing my car again. I did around 210hp on a 105 degree day 2 years ago. Once it gets real cool I'm going to wait for a pefect day, preheat the oil and run in on a cool engine to see if I can get some crazy hp numbers for a stock 5at.

That may be it. Obviously the 200hp (the really low one) was way off, lower than a bone stock 5at. Definately go back to the original dyno and stick with that one for comparing mods.

Will do, i will try to get it done soon. I'm still going to do the compression test for the hell of it, i wanna check my plugs anyway. To think the only reason i went to the dyno was because it was dyno day and wanted to have some fun with a few buddies and also see if the throttle body spacer robs us of power or adds power or nothing at all. Instead i had a very stressful day. Once i re-dyno at the original place i will post on here the numbers for everyone to see...i hope the day i do it the weather is similar to the day i did the 269...since i'm on long island i might have a shot at that happening. Thanks for the posts

oh and just an FYI when i got the 269 number it was about 80 degrees out and when i just got those low numbers which was yesterday its been in about the 60's....we will see when i re-dyno

I'm curious how it's going to do on the original dyno. I have a feeling the numbers are going to be very close.

I wouldn't say 269whp is abnormally high for what his car has. For arguments sake, let's say stock the 6MT TL makes 225whp. With I/E/PC Deletes/Jpipe I'd say it's possible to gain 40whp. After E/Jpipe (which add about 15-20whp when combined), the PCDs add another 10-15 alone as seen from a few dynos.
I would definitely still do the pressure test just to make sure. I mean, 205 on that dyno seems very low. That's the same dyno I got 255 on. Maybe it was calibrated differently? I mean, I can't see that much of a swing from the calibration alone though.
What gear did they dyno in Ant? That can also play a factor.

I believe it was fourth gear, you wanna come with me when I go to no limit again?

The only mods he has that would show up on a dyno are the exhaust mods. Whether it can or can't make that kind of difference, I don't know. But it's on the high end of normal for sure.
The pulley and CAI will make no difference on the dyno. The hood is already up, CAI is ineffective, and the dyno is done in 4th gear so the pulley is ineffective. Spacers don't make a difference anyway.
If he dynos almost 270whp again on the same dyno, I'm ordering a complete exhaust from the precats back.

I always determined dyno whp by Trap speeds at the track. For example I knew that my Wrx with 320whp on a dynojet would trap around 111-113. Exactly what I got. obviously when I dyno'd on a mustang it went down to 296whp with the same trap times. It was a bit more tricky as i got to 400+whp because of tire spin and boost issues.

I did the compression test last night and the numbers were good. 4 of the cylinders were 150 psi and the other two were 125 & 135 which are still in the range of being good. My spark plugs were in good shape however the three in front seemed to be loose. When I put everything back together and tightened the plugs how they should be the car seems to run smoother. I will probably dyno next weekend.....results will be posted.

Oh dude, sorry about last night. When you called I was on the phone with my GF and I forgot to call you back. Hit me up later.
correct dyno gears:
04-08(all) automatic is 3rd gear with a 1.07:1 ratio
04-08(all) manual is 5th gear with a 0.98:1 ratio
auto:
First Gear Ratio (:1) 2.70
Second Gear Ratio (:1) 1.61
Third Gear Ratio (:1) 1.07
Fourth Gear Ratio (:1) 0.69
Fifth Gear Ratio (:1) 0.49
manual:
First Gear Ratio (:1) 3.93
Second Gear Ratio (:1) 2.48
Third Gear Ratio (:1) 1.70
Fourth Gear Ratio (:1) 1.25
Fifth Gear Ratio (:1) 0.98
Sixth Gear Ratio (:1) 0.77
OP i think you have been dyno'ing in the wrong gear leading to false numbers

^ After reading this post, I don't think people should give our false information to the community. Even though it's a year old thread, it can still throw off new members who think they should dyno in 5th gear. Your wikipedia find is what it should be, but 4th gear is the power band you want to dyno your car on.
Just think about tracking the car, your car will not hit 5th gear in the 1/4 mile, so the power to tune the car would be 4th. 3rd gear would be reasonable for part-throttle tunes, Wot's on 4th and maybe 5th gear to see what you'll make in that gear. I don't see much MODs correcting many misleading posts which in turns leads to other's ruining their car. BUT.. I'm sure your tech/tuner will also correct you on this as well.

To get relevant numbers you would always have to correct the torque numbers for a 1:1 ratio.

As long as the gear ratio, final drive ratio, and tire size are taken into account, it really shouldn't matter what gear you are in, to a point. Due to the time sensitive nature of a dyno it would make sense to run in the highest gear (6th being the highest in this case) possible so that you get more accurate and consistant numbers.
For clarification: highest gear possible means that you are able to reach redline in that gear.

Good post. But, the only reason we don't/shouldn't dyno in 5th is because of the limiter. Being set at 135, it prevents us from exceeding say, 5800RPM in 5th, which is before peak power. If there were no limiter, based on what I've heard/read, you should do dyno pulls in the gear closest to 1.0, which would be 5th.
