WOW that was so funny ! I dont think anyone knows how fast a 200hp to the wheels<<< sub 2500 pound car will run in the 1/8 mile with good traction. My buddies runs around a 9.0 with an open diff.........im gonna say around 8.5 will be in the very near future.

Maybe heavily modified mustangs or ones on laughing gas. My buddies 99 z28 only ran 9.3's ballpark with headers/slp lid/k&n and all that nutz.

Keep in mind traction is a big factor here since 240's arent really "drag" platforms.
Had to get that off my chest i really dont think people get it. I mean a rb20 and sr20 only make around 200 to the wheels guys.

Wait what? A 200hp 240 running a 9.0 in the 8th? I call s***. My best time in a HR z was a 8.9 and that was keeping up with twin fd's and sr'd s13s... Prove me wrong please id love to see a sub 200hp s13 running 9.0s

I have pretty much been in every 240 swap posable ka-t,sr,rb20-30, ls,vq... An i have to say out of all the 4 bangers and 6 slingers i have been most impressed by a ka boosting 14psi so i know first hand they have potential to do good things , just not n/a

Well heres a old video....yes i had purple wheels im just not a painter....
http://www.youtube.com/watch?v=qkiSwDGfx1k

I was running 4psi kat best time was 9.6 (FMU/welded diff/ghetto as crap) --roughly 160-170 id guess

Buddies car in far lane has an OLDblacktop SR20 stock everything but a FMIC / open diff. but had NITTO tires ran 9.0* --roughly 200 ballpark

There are of course other factors like for instance in the video we had excellent track conditions and weather! I also cant drag for snot and he is one of the best drag drivers ive seen.

4psi on 2.4 ka....iv seen 50cc scooters push more psi then that. And 160hp is just down right stupid for a turboed ka seeing as a stock n/a is right around 150. :squint:

What the hell turbo are you running on 4psi? I bet your power band sucks!

Nothing you are saying adds up. And i dont like it!

Edit: After watching that video i hold by everything i said. I see no times and it sounds like a solid high 10s run to me...

Lemme try to end this bench race here before we go callin rotary engines reliable :rotfl


First off import tuner's cat back exhuast S14 only made 121hp....
The latest S14 had AEM short ram/cat back exhaust and the coveted 248 cam mod making a whooping 140hp...

I would LOVE to see a bone stock 240sx put on some rollers that would be EPIC -->150 is a joke right.

Ill have to admit 4psi yes very dumb needless to say i had some issues there. The good news is i learned exactly what NOT to do and it was crude to say the least.

help-t25-turbo-clocking-t530731.html


Id take pics of a couple time slips i got but eh you figure it out. Heres something to think about HR z huh.... 305hp to the crank 3600 pound car little research----

this is from nico actually!!!!

I would be interested to see the standard de and hr done at the same time and place, get a real reading of the improvement, and keep in mind all dyno's should be the same but they are not! I've seen stock 350's turn 240whp on a dynapack only to pull 225whp on a mustang dyno, and gine the sae ratings formula change I'd expect the hr's to be in the 260-280 whp range



hmm punch some of those numbers up on here guy http://www.hotrodpitstop.com/tool.php#1

When I had a KA, I made 145 whp/155 ft lbs on a Mustang dyno with intake, header, exhaust on a stock S14 KA. When you factor in the 12% conversion to Dynojet that would be about 162whp and 173 ft lbs.

Try again. 08 hr Z with full nismo cat back, berk highflow cats, nismo headers, aem intakes, and apexi filters. Along with a few other odds and ends. I would cry if that car only put down 305 to the wheels...

It is try that dynos change from place to place but anyone that has been around cars and knows what there doing can ball park what the hp is. I infact have become pretty good at it and can come within 15-20hp most of the time.

Im not trying to be rude or call you out i just dont see the numbers your putting out adding up.

Ill find some of the old stock de dyno runs before and after exhaust, cams and header, intake next time im up at the shop. Car was dynode on the same day at the same place, in the same condition so theres not a lot to argue about.

I believe Zenki is correct here. With the aid of google :) , I found a dyno chart from an HR Z33 with similar bolts ons, but with a technosquare reflash.

Im well aware of dyno differences and that they serve as benchmarks not percision measurements. The reason i reference import tuner is that they tend to use the same type dyno and their weather conditions *cali are also the same.

I really dont think their is a conversion for mustang vs dynojet 12% i suppose that could be correct. If it is id say your got a keeper of an engine only thing i can think of is altitude and temp. where big factors? Reguardless this wont ever end lets wait and see what that little 200hp can run down the strip.

As long as hes got some beef back there to hook up really nice im gonna say 9.0 flat will be a best time 9.3 average.

Agree to disagree i guess. Ill be checking in on this to see some 8th and 1/4 times. I dont foresee a 200hp sub 2300lb car getting close to a 9.0 though. I would be more then happy with low 10s with a low et off the line.

Nice find i was keeping up with his build over on my350z and he helped me when i was buying a few things for my z. people are really all up on his nuts in love with that car for some reason. Iirc he is running some 19x10.5 in the rear so im sure theres a few hp being waisted right there but never the less some impressive numbers being put down.

12% is a fairly agreed upon general conversion. :) It was a Texas summer, so fairly low altitude and 100 degrees F outside. Engine is gone and replaced with something much better now anyway.
