As some of you may know I had a bitch of a time getting my car running over a two week time period, and this is the end result -
Run 1

Run 3

Do remember, the air temperature was 100 degrees at time of testing so numbers are on the low side. This is the result of my work, and all of your guy's help

nice #'s...

 

good deal

 

I'd say those are pretty good numbers actually, especially considering the temp and those numbers are at the wheels.

I also plan on going back in December with more goodies (and colder air) and seeing what it can do. I have a question though, what would this number look like on a Dynojet? I have a plot of a stock A6 with a gutted cat and he made -

is that the weight with you in the car?

 

Well it wasnt the 300whp you promised me last night, but congrats Edwin

 

how many miles is on this bad boy. very nice numbers. keep it up.

 

nice numbers. I forget what a stock d16a6 makes to the flywheel but those numbers sound good.

 

Glad to see everything worked out for you doc. You've helped me in the past also,

rated 108hp

those are some good #'s dude.

Actually, a stock D16A6 produces HP and torque numbers that are pretty close (108HP, 100ft-lb or 105HP, 98ft-lb). But the reason why you don't often see HP and torque numbers that are either the same OR torque numbers that are HIGHER than HP numbers in imports is simple: displacement. We are talking about small, four cylinder engines here. And torque is limited by displacement. The fact is that you CAN'T get torque alot higher than it is even in stock form. So in order for torque to equal or exceed HP, HP has to be low. And none of us want that! Only when a motor is VERY large (ie a pushrod V8) can torque be higher than HP, yet with respectable HP. But even with domestic V8s, anything considered high performance will produce numerically higher HP than torque. The LS6, for instance, produces 405HP, 400ft-lb torque. And the LS7 produces 500HP, 475ft-lb torque. So having equal/higher torque compared to HP is really just telling you that you are not producing the kind of power that you could potentially be producing.

 

good #s

 

damn that torque line is

 

Looks like someone let off the gas in the 2nd run. Also your charts dont look quite right, your hp shoudl climb all the way to redline yet your peak power is a couple hundred rpm off in the first and I dont know what happened in the 2nd, heh. But still good numbers.

Also as far as hp/torque, hp will ALWAYS exceed torque if the motor is reved over 5225 rpms. The ability to make torque up high is very important.

 

Bottom end torque is underrated.

I drive 1-3K RPM proly 75-80% of the time.

It's everyday power you can appreciate.

All packaged up in a light COMPACT SOHC design.

 

congrats to the Dr.

Probably a typo, but it's 5252

i don't like hearing this because how much torque do you need? I'm driving a CRX right now with about 100 ft-lbs. I'd gladly rather have 160hp (where i need it when i'm racing) then 160 ft-lbs down low (where i wouldn't really need it). I'm not downplaying torque because it is a big deal, but the whole 'daily driver' excuse is kinda dumb because you aren't using the full power available 75%-80% of the time so why do you need more?

Yea I just love seeing it posted up. I might rebuild an a6 with slight headwork and see if it gets any good gains.

lol, i thought i recognized that graph!
(still cant believe your oil spitting a6 almost beat mine...)

As with power, the line of 'more is better' applies to torque as well. But I guess it is all a matter what it is going to 'cost' to get that torque. For instance, going from a B16A to a B18A/B18B will give you more torque. But that torque comes at a hefty cost in terms of losses in other areas. For instance, you lose about 20HP in the process (vs gaining only 10-16ft-lb torque). Also, because the B18A/B18B doesn't like revs too much. So it is not the best idea to run this motor with a VTEC transmission. This eats away at some of that torque. I can tell you from my experience that going from a B16A/JDM S1 to a B18A/B18B with an LS transmission is a BIG step down. The bottom line: trading HP for torque SUCKS! On the other hand, if you gain both HP AND torque, all is good in the universe. When I upgraded from a B16A to a JDM B18C5, the only cost was money. Otherwise, the B18C5 is better in EVERY way possible than the B16A. The same goes for upgrading from an LS to non-VTEC B20.
