How much power would you expect a stockport 12a to have with intake, header, and straightpipe/open header? All accessories removed. Any guesses? I'll need about 140hp to break into the 13s stockport, though it might be possible with 135hp.

And yes, a 1700lb car with 180lb driver can do that with that much HP.

Possibly 130-135

that's basically exactly what i have done and i have 110 rwhp. so that's probably about right.

Gregs

13s? as in 13 second 1/4 on a stock port?

man.. if thats possible then i better get to work on my car.. that is until its tII time!

-greg

btw how did u get your car to wiegh 1700 lbs?

-greg

Amagi82

shoot, that means I'll have to do a bit more weight reduction... 1600lbs anyone? lol

Amagi82

Well, I havent weighed it yet, but judging from what others have done and weighed theirs, and from the SLK230 I just beat pretty bad with ~75 extra pounds on my car(they do 15.2 stock)... 1700lbs should be cake. If it isnt there yet, it will be when I replace the side windows and rear hatch with plexiglass. I might get crazy and replace the windshield with plexiglass, but only if I need to to reach 13s.

Basically, if its not required for the car to drive, I removed it. No extra crap under the hood, no hood on drag runs, no dashboard, no useless crap in the interior, no passenger seat, no spare tire or jack, virtually all sound deadening gone, no windshield wipers(wiper in my passenger seat for legality). You name it, its gone

Hmmm, how can you get 150hp? Would a good carb and intake manifold pull that off? Whats the max power you can get out of an NA stock port 12a?

Gregs

i think its in the range of like 150-160.... but thats pretty hard to do.....

Amagi82

What else is there after the header, exhaust, intake manifold, carb, and intake? I just read another thread which says 150 is the limit with stock ports, on a very good day 160 might be possible, and that it may not be nessesary to upgrade the carb until you go with porting. So if header, exhaust, and intake gets me to 135, is a good intake manifold the difference between that and 150hp?

Gregs

is that 135 FWHP or RWHP?

-greg

Amagi82

Hmmm, with 150hp I'd need to get it down to 1400lbs to get into the 12s... that would be VERY hard to do. Perhaps not impossible, but it would require LOTs of sawzalling... probobly sacrificing significant structural rigidity. Perhaps 13s will suffice for stock ports, lol

Amagi82

flywheel i assume

Gregs

dude are you using one of those quarter mile estimater programs?... ive heard those arent very accurate....

-greg

Amagi82

I'm using cartest, which so far has been fairly accurate, though conservative with my RX-7, proven with 1/4 mile slips.

Gregs

ok if its proven to work then thats cool...

-greg

Amagi82

I should add.. conservative only because I've been powershifting.

I've seen an r100 at the track with a 13B stockport running high 13's and that car is about 1800 lbs but he also had some drag tires on it.

BRealistic

How much power can a stock port 12a make if you leave all the accessories on it? I guess that would be all intake and exhaust? I like my a/c when stuck behind old farm trucks on backroads.

sweetege

Well since he never gets on here my bros 84 se weighs 1440 with a full tank of gas.

Amagi82

1440!?!?! how did that happen?? are you serious?

Amagi82

if it stops raining today I think I'm gonna try to get my car weighed.

Amagi82

hmm, i think I'm gonna make a fiberglass passenger door. That should cut an easy 75lbs or so.
