How much power am I making?

[oneslowwdsm]

So I hate GUESSING my power output. I know I should just get the car dynoed but no time for that I'm truly surprised at my setup at the moment and I just want to see people with similar setups chime in.

Car:
2g AWD 6 bolt swap with some type of higher compression pistons. (had 180psi accross) Stock cams.

Currently:
1000cc's
E85
22lbs
Small 16g turbo
FMIC

At 22lbs my wideband is in the 10's. My tune is setup for a 20g turbo at 23lbs, not a 16g hence why I'm running so rich but I haven't put the 20g on yet. Just the mail order tune, injectors and fuel.

My guess is 350whp but am I overshooting it? Honestly, I had the 20g setup on my old 2g with the same mods and the 16g for some reason feels just as fast maybe faster or maybe I just haven't been in a 20g car for a long time.

What do you guys think?

 

[bryanwheat]

200-300 would be my guess. It is pointless to guess on something like this though, there are many more factors other than psi from the turbo and a/f ratio that will determine how much power you are making.

+1, and this should go into the bench racing thread. If you dont have time to dyno, you dont have time to know your power output, how do i know this? ive been running an SCM6152 and never dynoed, i can guess all day at what i might be making but ill never know til i go do the deed. HX40 this time around is 100% getting dyno love at english racing.

You guys are right please move this thread where it is supposed to be. I just wanted to see people with similar setups. It's pointless to take my car to a dyno unless it's free or I get link and tune my car on it.

Your smaller turbo just probably feels more torquey in the low end, that's why you might think it feels faster. But the 20g will pull more on top end.

probably 200-300hp, but the only way to know for sure is to hit the dyno.

 

[Bud92gsx]

The reason your 16g feels faster than the 20g setup..My edjucated guess would be turbo lag.

Even if the 20g is a few hundred rpms slower spooling. Well actually more than that..The small spools a tad higher than a 14b.

So lets say 3k, vs 3.5k..Faster spool may feel faster.Even tho power may be higher on same setup with a 20g vs small,evo 3, or 14b spool wise.

How are you running 1000cc injectors on E85 @ 22psi when your profile lists engine management as "stock?"

Because you reference "My tune is setup for a 20g turbo at 23lbs, not a 16g "

Are you on a chip?

 

[Stew Pidaso]

If you have dsmlink I've heard that if you multiply airflow by 10 it should give you a rough estimate on your power output. I put my car on a dyno then read about that little "calculation" and it came out to be damn close. Just thought I'd throw my .02 in here

Well it's not pointless you will know your true HP and TQ But I know what you mean, it doesn't need tuned or anything.

Yes, I never updated my profile because my setups change a lot but the 20g should be the final setup once I get it rebuilt.

This is assuming that your a/f ratios along with timing is correct. Airflow can usually be directly related to horsepower to a certain extent if the rest of the tune is correct.

Yeah you and Bud92 are probably correct, I did think of that until I did a 2nd and 3rd gear pull (no lag) and 3rd gear feels better then 2nd it's possible that I may have cams in this car but I do not know for certain (previous owner didn't know anything about the car) but I can't tell with the valve cover off.

 

[LandSpeed-DSM]

Estimating power by airflow using the "1lb=10whp" figure is assuming you are taking full advantage of that airflow with MBT timing and a lean, hot burn. Among other items.

On an octane limited setup, like pump 91 or 93, that can be wildly inaccurate.

You can use known weight/tire height/gearing and 70-90/60-80 or Quarter Mile times to make a more informed guess as to power production.

 

[talon2gbuyer]

Look around for local speed shops running a dyno day. Be kind of interesting to know what your car is pulling. As for estimating you really cant tell, assuming you have no boost leaks/vacuum leaks and the pull is perfect who knows.

click on the member tab and select quarter mile or by turbo setup, you can find out what people are making on different turbo platforms Or what mods they used to reach their 1/4 time.

you say this now........ i know more then just me will agree

 

[GSTurbo1]

See how many horses you can drag behind you the # of horses will equal your horse power!

Wow I did not know that, that's awesome, thanks!

uh, i think horse power is determined by how many horses it would take to pull something.. to equate the same power level not how many dead horses your car can drag behind youl..


we all know a 20G wont cut it for you as your final turbo , when i first got my car i thought my final turbo was gonna be a 16G, bought it, and never installed it went pte 6152, now im going HX40 just an example of how it typically goes, you will always want more boost, and to go faster

Lol yeah that's true.. you know as long as the block stays in-tact then maybe I'll go bigger

From what I'm seeing, very similar 16g setups running over 300whp on e85. I might go get it dynoed just for fun once the 20g is on and probably get my heart broken

. Its not the power you have.... it's how you drive it. .

40psi ftw

 

[boost97gst]

e85 and 10:1afr?? shoot for a safe tune of 12 to 12.5:1 on straight e85 dude. You can put down very good numbers with eth and link with a 20g

Bench racing = not allowed in the tech forums.

Further discussion can be done here; or you can simply take your car to a dyno and stop guessing.
