Got my car dynoed saturday and its not good

I got my car dynoed yesterday and its not good. My car has 4300 miles on it with aem cai, dc sports header and tcs exhaust and here are the results of the two dyno runs.

dyno run 1: Max Power = 110.7 Max Torque = 102.9
dyno run 2: Max Power = 102.8 Max Torque = 93.7

So, theres the number before my head package comes in. I also found out that it will be delievered on june 18th. Well, im kinda disappointed but expected those kinds of numbers. Oh well, this is my first car and DEFINITELY not the last.

later.

On the second run the car was already hot, so that probably caused the losses seen. I didn't think they would be that much though.

That's is reasonable... somewhat... cause the advertised 127hp or 117hp is at the flywheel...your dyno was at the actual wheels.... Si (Ex) can only pump 110 at the wheel

what trim do u have dude?

if its ex... then those bolt-ons didn't do crude... wow... because stock dyno is right about there... 110-112 hp... 100-105 lbs-ft torque...

if its dx/lx.... then those bolt ons actually did do something! wow!

but you probably have an ex.... and those bolt ons... just makes noises... and waste gas...

Without numbers from a dyno run made on the stock car, no one has any basis to make any statements about bolt-ons! Let's keep it rational!

Thats about par for the course on our cars. Even with I/H/E you can't expect much more than that.

well, your bolt-ons did make some improvement because according to your first run of 110.7 HP after you take into account the difference due to driveline loss it is 135 HP at the flywheel so it's an increase of 8 hp from the advertised 127 of our stock EX's. good luck with gude bro

thanks for the condolences and my car is a 2002 ex manual with those bolt ons. I noticed the guy that was doing the dyno, on the second test he went easier on the car and his shifting wasnt that great. The car slightly jolted when he made his shifts. I dont know if this is from the dyno or if he's a bad driver or what not. But Im hoping I dont get screwed out of the gude head cause i have been hearing nothing but bad $hit about it. Oh well, $1650 isnt gonna kill me but at least I save you guys from wasting your money. I WILL have dyno results from when the head is put on and im lookin to do other things to the car to get a little more out of it.

im got the gude head package. Its a port and polish head, three angle valve grind, a regrinded cam, and a big bore throttle body. I dont what kinds of gains i will get but they advertise 45 hp to the wheels, but we will see. Please people, dont go out and get this head package cause its out. I fronted the money for this so you guys might not have to waste your money on a product that doesnt work. I WILL have dyno results after the car is done and it looks like it will be done in about a week and a half so please be patient. The reason why its taking so long cause Im having my head package, body kit, and wing put on all at the same time. I got the xenon body kit with the kaminari wing so at the very least my car will look good, but we will see . . . .

er. no.

stock 127 hp ex dynos at around 112 hp to the wheels... instead of the average 15% drivetrain loss, we're at like 12%. not bad huh?

how did you get 135 anyway? you're assuming a 20% drivetrain loss? thats a bit high.

anyhow, good luck with the gude package man. and its cool that you're getting those dyno results in for us... for you man.

Max power might not be affected, hopefully you gained in the lower to mid range over a stock EX. Who cares about max power, its the mid range that your in all the time trying to reach max power, then you shift, and your back to the midrange again. but im sure most of yall know that.

well, he said on the dyno his first run got in at 110.7 at the wheels so I assumed an 18% driveline loss and came out to the estimate of 135 at the crank. The 18% is from the owner of a dyno shop who gave me that figure so i guess take it for what it is worth. oh one more thing, you said our cars stock dyno in 112 at the wheels but how can that be if he dyno'ed his at 110.7 with engine mods??

okay, stock dynos at AROUNd 112, so 110 is right about there.

so how can he still get that with engine mods? hint hint. those engine mods didn't do anything. I can't say that for sure though, since I didn't get to see the dyno chart... I mean, maybe the peak horsepower isn't increase, but the entire power curve moved up a bit... (meaning he got more low-end and mid-end power, perhaps)

if you take a look at InJen and AEM's website.. they have stock 01 EX 5spd running at around 110-112 hp... and they both claim to have a 3-4 hp increase in their dyno graph... pumping power into around 114-116 hp range... we sure didn't see that number though... and thats with the intake alone too!

but who knows, maybe he did get some increase.... maybe if he is running stock now, he'll be in at 100 hp or something. I personally dont think bolt-ons do anything but make noise.... it may give you a few more hp... but it may take away a lot at the low end too...
