both runs were done on a dyno jet. and i did this on purpose for all you nay-sayers on the difference between 3rd and 4th just so you will stop. the runs were about 3.5 to 4 mins apart (to allow for the runs to be closer to the same and avoid showing heat soak). he hit the rev-limiter in the first one so its truely about 222-223. blue one is third gear, red one is fourth.

 

Putting down good numbers stock.

 

thanks...had to set a base point for myself too, intake is coming tomorrow and then the exhaust is sitting in my room at home. gonna do some update runs when i get back to see the gains.

 

good #'s for stock

 

A/F looks better than mine. whats a good number to stay at when at wot? i think its around 12 right?

 

yeah you wanna look for 12s afr at wot...

between runs the dyno guy and i talked at length about how it starts to lean out up top...

wayne (the dyno operator) was very impressed by the car. after the first run he asked me, you sure you havent done anything to it?

 

Yeah at least your Air Fuel Starts to lean back up, mine just keep going down.

 

sweet.

 

Not sure about it, but is the 2006 seems to be a bit leaner for the few last RPM's, thus producing a couple more HP ?

 

im wondering how bad the intake and exhaust will change this...

 

Well think about this. I have just the magnaflow on it. 2.5 catback. I raced my friends srt4 acr stock and he pulls on me from about 40-100 about one car length. After I installed my exhaust I pulled on him from 40-100 about half a car length. So you'll definately notice the difference.

 

ok, now im definately ready to dyno again...lol...

too bad he has to send his stack out for its scheduled maintanence...we were the last runs for it...

it should be back in by the time i get back from my break

 

no one has anything to say about the 3rd gear and 4th gear?? lol

 

What are the gear ratio's again? Aren't they like 1.14 for 3rd and .89 for fourth? If so, both should be about the same amount off- one high, the other low, both by a similarly insignificant amount. So with that in mind your dyno sheet isn't all that surprising. Well to me anyway, it's about what I would expect- maybe a little more space between them, but still- close. Hope this ends once-and-for-all the damned 3rd gear 4th gear dyno debate.

 

yeah, it looks like there is about a 2-3 hp difference between the two in the peak numbers...(being that he hit the revlimiter in 3rd), in some spots though 4th is either even with, or like not even half a hp above the third gear run

 

Thank YOU!!! I wish you were around when I pulled 230hp on a DynoJet in 3rd. F'ing Near EVERYBODY was Like 3rd gear doesn't count blah blah blah.

Thanks for proving them all wrong!

Dman,

I am a bit confused are you say that 3rd and 4th are the same or different? If you look at your dyno the HP curves are almost identical except the very end where there is a slight jump of 6 HP. I would say by looking at your dyno that there is pretty much no difference between 3rd and 4th.

 

exactly, many people have been disbuting this, that you need to use 4th gear for accurate numbers. but this shows that third will work also, that it does not make much difference.

 

in some spots there are as much as 2-3 hp difference, but when viewed overall, there really isnt a difference, i do agree. and whats really strange is that ive talked to wayne since then and we looked back over it...if you truely count out the spike because of the revlimiter, the peak for 3rd gear was only 221-223ish...and the peak for fourth was 220...

i plan on doing this again when i dyno with the mods in jan...

 

here is the third gear pull...

btw, i was standing behind my car at the other screen, the guy that starts jumping around like a idiot owns a turbo mr2...most fun ive had in jacksonville though...crazy people...

oh and to make my posts clearer, im saying what ive been saying all along...that there is no better reason to do pulls in 4th than there is to do your pulls in 3rd because there is no difference

 

Amen!
