Since alot of you are the proud owners of sr20dets, Pleez convince me not to get an Rb26dett... Lemme see your track times.. does the silvia limited slip make a big diff?

Post by **I H8 UR DSM** » Wed Mar 26, 2003 5:52 am

yes the limited slip would make a substantial difference.

12.8@109mph, stock motor, stock turbo, Open diff.

yeah stock turbo boosting like 21psi...HAHAWhat other mods u got Jesse? Just a 2000lb gutted car?

Post by **I H8 UR DSM** » Wed Mar 26, 2003 5:52 am

im stock ; )

Post by **Silviagirl79** » Wed Mar 26, 2003 5:52 am

Yeah right. Enthalpy hit 12.56 in his S13 with 360hp to the wheels. You cant hit a 12.8 and be completely stock...so whats your secret?

Post by **ItzGenX** » Wed Mar 26, 2003 5:52 am

Greaser on fresh alloy had a video clip of him running 11.19, and he only had around 356hp at the time of running that. --To Each, His Own --

dont know why the link wont work...

Stock DET goes 12'sAnd I do mean bone stock. I just got back from vacation but was at E-Townfor the Nira event on the 8th. I was wandering around the pits and saw awhite classic and figured I'd stop on by and say "hello". Well, I walk overand see the interheater and hood scoop. O ho hoooo what do we have here?Basically it was a high mile Sentra SE-R that popped the motor and theyswapped in a DET and left it in bone stock condition.

So I asked him what he planned on doing. Well "Joe" said he would be happyjust to make it into the 13's. I said well, lets see if we can do betterthan that, and got to work on the car. Joe was insistent on pulling thewastgate line and letting the turbo run free. According to Joe the T25spikes to about 19psi and then levels off about 15psi under full throttleacceleration. I look and see the stock DE MAF, injectors and theinterheater and said "Welp, if your going to do that lets at least knock thebase timing back to 15*, ice down that intercooler, and fill the tank withrace gas." I also regapped his plugs down to .021 (From .030+) as he wascomplaining about a misfire with big boost.I adjusted his slick pressure, and gave him some pointers about the burnoutand launch and off he went.

First run 13.3@106mph with a BIG bog out of the hole. Sweet! (Joe did youlaunch at 6000rpm? "No" Do that next time)

Second run 13.2@106 with yet another big bog out of the hole. (Joe did youlaunch at 6000rpm? "No" Do that next time if you want a 12 second run)

Third run the launch was good with some mild wheel spin to keep the turbo onit's game and Whooosh 12.9@108mph on a BONE and I mean BONE stock DET withthe cat on the car, 2.25" exhaust that was so quiet you didn't know the carwas running, stock MAF stock stock stock.

I was impressed to say the least, but at the same time biting my nailsbecuase I knew he was probably running way lean.

I never got anymore information out of him other than he is from Long Islandand was part of a shop called East Coast Motorsports or something.

Anyway just wanted to relay that story on over.

that car went a 12.5 that season, stock.

Post by **Silviagirl79** » Wed Mar 26, 2003 5:52 am

slicks are not stock tires....sentras are lighter than 240s too.

Post by **Silviagirl79** » Wed Mar 26, 2003 5:52 am

and with 15psi, and slicks I could probably hit high 12s in a 13 too.and 7 psi is stock, not 15....when you say BONE STOCK... I think of bone stock out of the factory. Sorry.

maybe for you they're not.....

Still the point remains that's damn fast for what he had done to it. Meanwhile I know 400+hp cars that cant do 13's and 380HP cars that are in the low 11's. It's all how you drive it.

stock is an arguable term : )

Id consider showroom condition, out of the factory : )

Post by **SRdS14** » Wed Mar 26, 2003 5:52 am

okay...guys, stock sr20's do hit in the 12's. a lot of the time it depends on the driver...

i guess some can't drive. i know i can't....

me too, I consider stock as in stock turbo, stock injectors, stock bottom end, stock top end. turning up the boost is ok, the rest is still stock. showroom condition is a seperate category.

I look forward to having my swap done, and being able to post up some time slips. My car will be a pretty much stock S13 redtop. It will have an intake, valve springs, RAS, 1.2mm metal headgasket, a Greddy oilpan, lightened flywheel and RPS clutch. The flywheel will skew the numbers a bit, but other than that it should be a pretty good, pre-bolt-on / upgrade baseline.

Post by **jmillheiser** » Wed Mar 26, 2003 5:52 am

yeah ive noticed that SR do seem to be pretty quiet compared to like a honda B series or even a CA.

in that video of the guy pulling an 11.94 on his SR powered S14 you could hardly hear his car (could also have been the straight piped camaro in the other lane drowning him out).

the one and so far only SR swapped 240SX here in cheyenne is VERY quiet despite his straight through exhaust (you can easily hear his t25 and BOV over the exhaust)

Post by **implict** » Wed Mar 26, 2003 5:52 am

hey guys, what do you think i would run with:

Just an sr20det, and MINES ecu. Based on good driving.

Any ideas?

( 7psi, no exhaust yadda yadda yadda.... fresh drop.)

not saying im gonna go to the track and find out... but i just want a lil clue.

Post by **I H8 UR DSM** » Wed Mar 26, 2003 5:52 am

14.7-15.8

Post by **implict** » Wed Mar 26, 2003 5:52 am

theres no way..

Post by **Dori Dori** » Wed Mar 26, 2003 5:52 am

You think that's too low or too high.

Sounds bout right to me...maybe a little faster.

Post by **implict** » Wed Mar 26, 2003 5:52 am

sounds 2 slow....

You're right for me they're not. By no means is boosting the hell out of your car...and running on slicks or drag radials..."stock." Now that I think about it. 12.8 with those mods is about right. I will run mid 13's boosting 14psi with my sr20det powered 240...I would hope I'd run high 12's on slicks...

SR20DET's (13's) run about 15 sec flat stock... add some bolt on like 3 inch exhaust, intake, 3 inch dp etc. You should be in the mid 14's with a 13. Do you have 3 inch exhaust, intake a dp implict? if you dont get them...they will make a world of a difference. These are the mods I have on my s14 (with s13 blacktop)...:

1. Apexi N1 Single 2. GReddy 3 in Downpipe 3. gutted cat 4. JUN chromoly lightened flywheel 5. GReddy Type S BOV 6. GReddy Turbo Timer 7. GReddy V-spl FMIC 8. Cone filter Intake 9. ACT Street Disk Clutch 10. Carbon Fiber hood 11. Dual 12 inch Electric Fans 12. Walbro 255lph Fuel Pump 13. Z32 Fuel Filter 14. No back seats

And it feels like a low 14 second car... Should run mid 13's with 14psi.. I am soo freaking happy.

maybe to you....feel free to post your time slip or report your times afterwards.....but you where the one asking the question, im just telling you what i know from experience being at the track, seeing stock Sr's run, and speaking with people who run stock boost...sure you may squeak out a 14.5, we'll see i guess....good luck, and may the force be with you! : )

To be honest, and im not trying to knock you one bit, i would expect to see a 15.3 timeslip, if your not experienced at the track (yes its very different then the street), and if you pull anything lower than a 14.5 i'd be suprised, but u have our support : )

Post by **Silviagirl79** » Wed Mar 26, 2003 5:52 am

He wont pull anything lower than a 14.5 BUT like I mentioned before I was told (by experienced individuals who own SRs), after they test drove my car...with a newly swapped sr..that the car felt like a mid to low 14's...on STOCK boost. HAHAAHA I love it.

I'll post up the time slips when I go to the track of my car on stock boost, an another of my car with 14psi.

Post by **I H8 UR DSM** » Wed Mar 26, 2003 5:52 am

A car can be a 13 second car....whether or not it "runs" a 13 is up to the driver...and driving down the track is much harder for most people then they thought....

be safe, good luck.

I am just now learning how to drive a manual...

in an sr, with a lightening flywheel...it stinks but I'm catching on. My hubby will probably be doing the track runs, he's a very good driver.give me some details on what makes the track so much more difficult?

Post by **I H8 UR DSM** » Wed Mar 26, 2003 5:52 am

Traction.

I can tell you i ran a 15.3 (@104mph, lol) on my first run, spinning first, second, third, and gripping in fourth....(with drag radials on the car, not street tires!!!)

Launching is the biggest part...most drag racing and races are won/lost in the first 60ft. If you run a 2.3 60ft mark, you did not launch/drive good, lol.....you'll be very suprised on how difficult it is to lower a 2.2 60ft to a 1.9 60ft...you'd think it might be easy, but its one of hte most difficult and aggrivating things in the world...

the t25 boost so fast that its hard to get off the line without spinning the tires....i do have an iron clutch, if i had an organic clutch (like most of you) it would help that 60ft time, slipping out the clutch, as opposed to dumping the clutch is going to allow you to get out of the hole with more traction, therefor lowing your ET....You'll also realize that a 'perfect' run does not happen 100% of the time...adn missing a gear, nto gettting a fast enough shift, little things like that, will make huge (1-2 second) diffenrences in ET's, and its amazing how such a little mess up will ruin the whole run...miss a gear, expect a 15 second slip...even though that miss only wasted .5 seconds, it translates into more....every little thing counts....

Then you come to variables like tire pressure...you wont get traction so you take out air from the tires to lower them, and give the sidewall more grip.....so your 60ft will be lower.....BUT then lower air pressure will make your MPH at the end lower, therefor your ET be the same as before...the matching of that stuff becomes very important...you cant just say "i ran a 14.2 w/ a 2.2 60ft , so i'll take 2lbs of air pressure out get better traction, lower the 60ft to 2.0 and lower the et to 14.0...but that ET could go up, because your slower at the finish....

its a lot of trial and error, and drag racing is one of the most complex types of racing, practice practice practice...
