Went to the track again with the RB26...

[Ramius83]

So, again we went to the track.

Car:

- 1995 240sx SE- RB26DETT swap- Running 13-14 pounds of boost- Speed cut eliminated- Stock engine- Stock suspension- LSD- 23" MH Slicks on steel wheels

Results:





12.060 and 12.068, and other miscellaneous runs (ie 12.110, 12.33, 12.35, 12.43, 12.53, 12.55, but none higher than 12.55).

What do you guys think?

[Kansei240sx]

Mods? Or are you running stock exhuast and everything too, if so thats freaking awesome!

[Ramius83]

I am running a BRM 3" resonated exhaust. No cat. Custom built down-pipe.

[sean8564]

that was awesome I want to take mine out to the track but there is only a 8th mile in Dallas I want to try to find a 1/4 mile

[Imissmyturbo]

Awsome times! What does the car weight? What kinda 60 ft's are you pulling?

[wawazat8402]

Sean8564, there is a track in Noble, Oklahoma. I believe it will probably be about 2.5 hours North of you. Isnt the Texas Mile in you general area as well? If you go to the one in Noble, let me know, Id love to see an RB26 powered S-chassis in person.

[USsil80]

wow that is great... very nice numbers.... can't wait to see what those run with just a few mods...and a good strut and spring combo

[sean8564]

Dude i have a RB25 and I live In GA Dallas Ga is the Nearest strip near me I am got a Rb26 to build and to replace the 25 in a few months or so

[wawazat8402]

damn, my bad, i thought it was dallas texas. haha.

[sean8564]

that is cool i will be taking my car cross country in jan to go to Cali to visit family It will be on the back of a truck It should have the 26 in by then maby I will pass through Ok on the way But for now I am in love with the 25It just got started a week and a half ago. and It was just not good for me power wise. I want Godzilla

[NightRyderNy]

Dont mean to steal anyones thread but i was just wondering where u got ur motors from RB26's from? Im about to buy one and was not trying to go through Venus Auto which i did for my SR.

[Wulfgang]

What do you guys think?

Insane. Only 0.061 to go before 11s.

Do you have any times with street tires?

[Ramius83]

Street tires would probably yield me mid-high 13s lol. I have no traction what-so-ever with my street tires. Next time I go, I will try with the street tires, once or twice just to see the results.

But yes, and next time I do go, I will have a decent spring/strut combo. I am looking into the Koni yellow inserts and the RS*R springs. I think this would be a good, semi stiff suspension for the track. I don't do any major autocrossing or drifting, so coilovers are not needed for my application.

[gawdzilla]

nice times! what kind of 60 fts are you getting? someone above asked but maybe you missed it..

[240240]

Very nice #'s---wish my Rb20 was that fastI ran a 15.5 @ 10spi on all stock motor except 3' exhaust

[supracrazy12]

hey ramius who cutom fabed you down pipe? and what was the cost? i was thinking about going with mckeney but 600 seems a bit much for just a down pipe

[Ramius83]

hey ramius who cutom fabed you down pipe? and what was the cost? i was thinking about going with mckeney but 600 seems a bit much for just a down pipe

My buddy and I custom fabbed it ourselves. Bought some 2.5" mandrel bends, four 2.5" 2-bolt exhaust flanges with seals, and some bolts and went to work on it. Didn't take but a couple of hours to do. Once you get that front turbo down-pipe portion to clear the steering column, the rest is pie.

Once I take out the down-pipe for any reason, I'll take photos of it for everyone to take a look. It isn't 100% perfect, but probably about 90% perfect. And hey, with almost running in the high 11s, it seems to be doing its job lol......

[sean8564]

Ramius where was that track I need to find one the only thing here is the Dalls 1/8th mile you Motor looks sweet who did the crome work on the valve covers

[Imissmyturbo]

It was pretty warm that night wasn't it? I be with just lower temps you will be in the 11's as long as you have traction.

Something is wrong with your RB20 or your driving.

What do you guys think?

What was your Tire PSI? and I didn't catch your 60' times.

[240240]

why do you say that?

I dont think its my driving---even though that was my first time running it

My car put about 196whp @ 10psi

[swwifty]

is that at commerce or silver dollar? I can't tell.

Nice times btw.

[Ramius83]

What was your Tire PSI? and I didn't catch your 60' times.

Tire pressure was at 17 lbs. Kinda high, but wanted to keep some top end there.

60' times were 17.5 ish, give or take a few tenths on each run. My 60' times are decent to me. It is my darn reaction times I need to work on.

is that at commerce or silver dollar? I can't tell.

Yes, it was at Commerce. Temps were about 80ish degrees.

quick questin, were you power shifting (not releasing throttle, stabbing clutch) or were you just shifting as fast as you could normally (releasing throttle briefly, stabbing clutch)?

[Ramius83]

I was releasing he throttle at every single shift point. I am revving the engine at 5000 and dropping the clutch. So I am already killing the clutch that much, I don't want to kill it anymore while going down the strip lol.....

Although, I may try that. I have heard of a few people doing that. Do you still press the clutch pedal and shift? Or do you just jam it into gear?

You should be in the 14's easy. 15.5 is something you can do with a KA + bolt ons. Try again.

[driftjunke]

With some suspension, you'll be in the 12's easy, your suspension is probably dead, I know all of my 95's were. 26 now Sean, you've only had the 25 for 2 weeks, was it because the vert left your's? Turbo Upgrade time, the 25's got potential.

[sean8564]

well My supplier in Japan made me a deal for a 26 in my container I could not refuse It was a half cut I will Tell you more tommarow

My understanding of power shifting is staying on the throttle while you puch the clutch and select the next gear.... VERY quickly. I've seen a lot of people power-shift at redline, meaning they bounce of the rev limiter while they shift, but i don't like that. I figure where i usually shift, take off 500 rpm to compensate the fact that i am on the throttle as the clutch is disengaged and quickly shift. I say give it a try, so you can get a feel for it then post back w/ some high 11's!!! man i wish i had the '26 instead of the '20 lol. Good luck
