that's great for me =p i live in La which most parts are under sea level

While you may see 10psi on your boost gauge (aka psig) at "9000 feet," I guarantee that the volume of air you're moving is much less than it would be at sea level. The further away you are from sea level the less dense the air becomes. The same effect can be felt on hot and cold days. Boost pressure has little to do with power. What's important is the volume of air you can move at a given boost pressure. However, that boost pressure will vary with mods and environmental conditions. Speaking in terms of ultimate power output 10psig at sea level is very different from 10psig at altitude.

Doesn’t it have something to do with the amount of oxygen?

Turbo engines, N/A engines hell any combustion engine loves to inhale rich thick humid oxygen! You get that best at sea level.

Post by **Snoboarder793** » Thu Jul 24, 2003 5:53 pm

humidity actualy doesnt make a difference id assume just the amount of oxygen molecules.

Post by **Unnatural** » Thu Jul 24, 2003 5:53 pm

It's the density (or lack) of oxygen molecules in the air. For instance on a hot day gases tend to expand and air becomes less dense in a given volume. On a cold day the opposite occurs. This situation parallels the situation with altitude. Typically, the higher in the atmosphere you go the less dense the air becomes and vice versa.

Thats far from true......enjuku racing's project 240sx ran high 12's with the stock T-25 on their DET motor (12.80 @ 109MPH)....Its all about launching, Tuning, and weight Reduction (which I lack too much of with my heavy *** car).......check it out for yourselves.....http://enjukuracing.com/subpages/ctw.htm......

soory the link didn't work.....goto http://www.enjukuracing.com and click on the project car link for ken's sr powered monster.....

If everyone can agree that there is 26% loss of power through the drivetrain, then I'm guessing my car has about 190 to 200 HP at the wheels. Enjuku's web sight said that Ken's car, at the time, had 240 at the wheels. That Red Top has had far more done to it than intake and exhaust. A STOCK S13 SR20DET puts around 140HP to the wheels. That's a 100 HP gain!!! Lets not forget. We need to compare apples to apples. My car is a '95 240SX with an S15 SR20DET dropped in, The only mods are to the intake and exhaust. No boost controllers, no AFR controller, and an inop tachometer. I just wanted to put the times up so that when someone did their S15 swap they would know what to expect realisticly. Most likely before you can get your car running, as I did, you will have to purchase the intake and exhaust parts that I did, at a cost of about $800. I'll bet that Ken's S13 has had a ton more than that spent to get those kind of numbers at the wheels, even at 240 HP. I just dont want there to be any confusion. Some these guys might think that the can throw in an S13 Red Top and their car will run 12's. It aint gonna happen. I promise. I would bet my left nut that if you take an S13 SR powered car and an S15 SR powered car, with exactly the same parts that I have, the S13 would barely break into the 14's, especially at the confirmed slowest NHRA track in the country.

On a lighter note. I got my first NISMO part today. A radiator cap. It's a work of art.

The best part about this whole thing...............My post is about to go it's third page.

w00t! :pface

You should get a working tach, SAFC, and FMIC in that order and as finanaces allow if you ask me. I think that will drastically improve your times along with getting used to the car. The tach is probably the biggest issue. You're most likely shifting before peak power right now...

mid 14's out of a swapped sr20det is nothing to brag about. With the proper engine management and good 60' times, you should run alot faster.

Post by **Snoboarder793** » Thu Jul 24, 2003 5:53 pm

y dont u post up ur times with the same car setup tough guy

Bristol? Cool. I'm from Wise, VA, bout 1hr 15min away from bristol. I'd love to see this mutant.

I dont think I'm reaching some people.

As soon as I spend the $1600 for the engine magement, FMIC, boost controller, AFR Controller, and slicks, I will be running 12's. My 60' times aint gonna get much better with the Kumho's. Give some credit.....GEESSSHHHH!!!

nisstek 13 flat is with a fmic, boost controller etccc.. its possbile without a differential. learn how to drive first with or w/o a diffy3llos14 power to ground is easy as long as your not driving on the street. the 1/4 track has a lot better traction. i barely wheel hope but you can only imagine if i did have a diff. its reality dumbass. you should just learn how to launch.

Post by **Snoboarder793** » Thu Jul 24, 2003 5:53 pm

scan ur time slip in and ill believe you.

Post by **sr240se** » Thu Jul 24, 2003 5:53 pm

sorry dude but i have it on tape at the track. hard to see but i will try to put it on here. And what in god names would i lie for??

Post by **Unnatural** » Thu Jul 24, 2003 5:53 pm

Nisstek, don't let them get to you. I'd say you did quite good for your first time out with a new car/new setup and NO TACH. I'm sure there's probably a little bit left in your setup as is, if you get your tach fixed (but you already know that). A 2.1 60' on street tires is pretty decent and is excellent if you're not running an LSD. Street tires just don't stick that well at the track. An R-compound drag radial is a different story but we are talking about pure street tires.

I think you did a great job despite everything you had going against you; altitude, street tires, no tach, etc... I think people are forgetting to look at the overall set up instead of the engine in the engine bay. It's easy to just call someone a bad driver but it seems that some are not taking everything into account. The tach problem alone is like trying to run the 1/4 mile with a blindfold on. I say good work!

Post by **sr240se** » Thu Jul 24, 2003 5:53 pm

Wasn't trying to put you down but very good runs. It can only get better

All i have to say is more mods!!!!!!!!! to come for ya

Post by **nisstek** » Thu Jul 24, 2003 5:53 pm

Thanks for your comments, unnatural. Somebodies paying attention. Dont worry, I'm not going back until I get a tach. It should be here within the week. I wish I would have waited to post anything until afterwards. But them somebody would have found something else to slam me about. It's all good, though. Hell, what do I care. My 240 has an S15 SR20DET in it.

Post by **GodzillaFan** » Thu Jul 24, 2003 5:53 pm

jesus christ people, hes driving w/o a tach.. at the slowest dragstrip in america.learn how to launch??? he was pulling 2.1 60ft.. thats excellent for a newbie

btw... i would expect an s15 with full exaust and stock everything else to dyno close to 250whp...s13s usually do 200whp with intake/exaust..

Post by **corn322** » Thu Jul 24, 2003 5:53 pm

hmm... how much does humidity affect an internal combustion engine? it seems to me that with high humidity, there would be less o2 in a given volume than at less humidity

Post by **Jookmasta** » Thu Jul 24, 2003 5:53 pm

cmon guys, no tach!!!!!!!!!!! he's shifting when he thinks its sounds right????? lol. excellent job nisstek.

Post by **sr240se** » Thu Jul 24, 2003 5:53 pm

Just keep driving blind

Post by **y3llows14** » Thu Jul 24, 2003 5:53 pm

Sr240se.....you gonna need a differential to drive...its either open or limited slip etc.. ....i was just messing with ya

Post by **MainEvent212** » Thu Jul 24, 2003 5:53 pm

jesus, i misunderstood...NO TACH! THAT'S ****in amazing...

Post by **Jookmasta** » Thu Jul 24, 2003 5:53 pm

exactly. and remember that it is an sr20 which loves to rev itself so he couldve been shifting at four or five or maybe even earlier. if it was me without a tach, i wouldve gotten a slower quarter mile time than an NA KA. lol. he's got skills.

Post by **mmdb** » Thu Jul 24, 2003 5:53 pm

i plan on doing the same 6 speed swap. Are you using the s15 gauge cluster? So i assume u wired everything up correctly? Show us some pix please!

Also how's the 6 speed feel? Are the shift gates pretty firm? I want the 6 speed so i don't have to get the 5 speed slush box :P
