Yay, I finally hit 13's been looking for it since I started spraying long ago! I finally got it. Here is how the night went down:

Race weight 3150, 22" MT slicks at 15psi

Best ET and 60'
RT .297
60' 2.278
1/8 9.131 at 82mph
1/4 13.833 at 105.8mph!!!!

Best Trap Speed
RT .132
60' 2.671
1/8 9.506 at 83mph
1/4 14.157 at 106mph!!!

Another good run
RT .150
60' 2.361
1/8 9.239 at 81mph
1/4 13.9 at 105.27mph

It was my first time using the slicks, at first i wasnt heating them up enough and was getting mid 14's. then i just lit them up, and brake torqued the hell out of the car, car took off kinda nice, and finally got into 13's. Something very interesting, on my run that i ran best trap speed, notice how bad the 60' was and yet i still ran a 14.1, If i would have done at least a 2.3 in that run I think that would have been a mid/low 13sec run.

So conclusion, I need to fix my 60' !!!!!, 2.2 is my best EVER with any setup. But i think its not my launching technique, its just my lack of power down below, or i just dont know (would like some advice plz). I would GREATLY benefit from a high stall TC, maybe a 2800, so i can launch with at least 3 or 4 psi, im launching with nothing. 0.5psi maybe.

I also logged, intake air temp, timing, water temp, inj duty cycle.
The only thing i am really not happy about is my very high intake air. at idle while staging was at 134F, then did my run, went down the track started going up to the end of the track and was at 172F!!! is this too high? wat temps do you boosted guys see at the end of a run while in full boost.

Grey99: i would like to know, when do you lock your TC, i think it may have affected my times how i was locking mine. most of the time I locked it at around 3.5K, sometimes i locked it 4k when i was in full boost. I think i noticed the car pull lil more when locking it lower rpms.

 

congrats, I know the feeling of hitting 13's and being alittle upset could you know the car can do better

only tip I can think of is stage as swallow as possible I mean just barely break the 2nd beam this is a old skool trick, what happens is when you stage like this it gives the car a chance to start rolling before you trigger the timing light I am pretty sure grey can give you more details about it

or maybe alittle 35 or 50shot of nitrous from 1800-3000rpms to get you started

 

I know you know this, but: Your trap speed says you've got more in it(lower ET) w/ a better launch/60'.

 

Your slicks are too small.

 

It helps gearing for autos. Although, perhaps you could try taller ones and see what the difference is. Jime always used small slicks due to the fact that it really helps the 4AT's tall gearing.

 

Drop the pressure more in the slicks and see if that helps. 106mph ain't bad, nice work.

I've never logged IAT so I don't know what mine are but I don't think yours are too bad. I'll have to do some looking at what IATs turbo cars see.

What are the specs on your turbo? Mostly concerned with what compressor wheel it is - that is what would affect IATs.

 

My turbo, T04B, .60ar compressor, .69ar turbine

 

Reason i got these is because jime and grey us them, and since we're auto it helps the gearing, quicker rev and acceleration. and they both were (or are in grey's case) spraying out of the hole with high stall TC. so i think they are fine. I didnt have problem with them, didnt spin or anything, just wasnt enough power to do better at 60'. at one launch i did get some slight spin but may have been for lack of heating them up

 

Congrats man. I'm thinking about hooking up my nitrous kit to see what I can do with it. It would be cool to have my max as fast as my Z.

Its crazy how much your car looks like mine.

 

thanx
and yea man i used to be blah about my cars color, but now Sage Mist Green FTW!!

By the way dude, how were you able to get 2.1 60', what tires, wheels, did u brake tq, if u dont mind i would like couple pointers, cuz if i can get a 2.1 i will be mostlikely in the mid 13's or at least a 13.6.

 

Usually I can cut 2.2's all day. That was the first time I got a 2.1. My car has never had traction problems at the track so I can basically floor it at the line. I usually torque it to about 1500 - 1600 and floor it. Thats basically it. I had my stock sawblades and bald falkin zeix 512's. The video of that run is in my signature not sure if it will help though.

Now my Z is a little more complicated. I've gotten a 2.009 on my stock tires with it. But since its rwd I dont know if my tecnique would apply to the max.

 

damn dude. it took me slicks to be able to get the damn 2.2. Ever since i started going to the track I have hit 2.3 no matter what i do. Launch from idle i get 2.3, brake tq the hell out of it and i get 2.3, just dont know maybe its just lack of that quick response or something. i was so happy with the 2.2 60'' lol. i want a 2.0 one day. It looks like im going to have to hook my nitrous back on and spray at least a 35shot from the line, then shut it off at 3k when im getting good amount of boost.

 

bet you coulda done that 2.2 on your street tires if you would have tried them out :-X

You did awesome tho homie, congrats on the 13s finally.... bout time!

 

Dude streetz its about time you hit 13's. Congrats see you tommorow.

 

I wonder if pulling on the handbrake and reving up the motor while in gear will work better then brake torquing.

 

Congrats. Definitely more there if you can lower the 60's a bit. Having the auto though it's tough without more low end torque or higher stall... so spray! lol

 

I say spray the 25shot off the line, should fix the problem

 

thanx guys. well these are my ideas., i cant do all of them at same time cuz the funds are limited, but here is wat im thinking.

Smaller a/r housing on the turbine maybe .58 (i have .69ar now), maybe this will lower the rpms in which boost comes in and i can get some boost off the line.

Spray out the hole about 35-50shot then let off the nitrous when boost comes in

or

Get a high stall TC

I think spraying out the line will give me the best results, but dont kno. i dont know if i wanna go back to nitrous.

 

I think spray is the best option. Cant wait to see what you can do with a 1.9 60'.

 

I ran up against him on one of his passes. Mannnnnn lemme tell you...thing starts BOOKIN once the turbo spools up. Good runs my dude...

 

All those specs are the ones that mean nothing for IATs. What I need to know is what compressor wheel it is.

 

This is all the info i have on the turbo

GARRETT Turbocharger (N1 type)
0.60A/R Compressor Housing
62 Trim Compressor Wheel (35lbs/min)
0.69 A/R Turbine Housing
79 Trim Turbine Wheel

 

hmm, where'd you get that info from? Because the wheel trim (62 trim) doesn't make any sense and doesn't exist to my knowledge - never heard of it and never seen any mention of it nor can I find any garrett compressor map for that wheel on any compressor map listing. Did you buy it used and that's what the seller said it was? There's a 62-1 T04B but the 62-1 flows like 62lb/min. The only T04B that I know of that flows around 35lb/min is the S3 that flows about 37lb/min.

What I'm getting at is that if I knew the compressor I could look at a map and get a good idea of where you're at efficiency wise. Where you are at on the map determines how much heat you impart to the air as you compress it. Being in a higher efficiency part of the map means that you heat the air less as you compress it and of course less heat is better.

BTW, where is your IAT sensor mounted in relation to your turbo and in relation to the throttle body?

 

Neal I think the compressor is a 60trim from my recollection. Streetz got the turbo from me (I never installed it), and I got it from aic96max

 

Spray off the line for god's sake!!! Just remember who said it first lolz

 

Street congratulations , you are giving some badass meaning to your nickname, btw grey is also helping me up with the tranny, you sir do a great job with autos , and of course you can improve those 60 foot times, i go 2.1-2.2 with DR's, keep the good work

 

awesome runs ! any good races to talk about, any photos or vids ?

 

Thanx guys, Nealoc, ya dude i bought it used so to be honest i dnot really know the tru specs of the turbo only the housing ar's since it says it outside, also says M24 if that means anything to u.

Goliekeg, nitrous is almost in already lol, already got RPM switch on its way in the mail, and now i gotta find a main line.. Im going to be spraying from the launch to about 3500rpm, thats wat the rpm switch is for so i dont have to worry about pressing buttons. Im thinking of 50-75shot.

Turiman, thanx. and yea I learned alot from gray i just need to improve those 60's.

Ceasars, thanx. Well as far as good races, my first few races low 14's i raced a PT cruiser that was turbo and automatic, older guy, reminded me of grey n jime, was cool. He had a better launch and was ahead then i ran him down and almost passed him (i belive i did 14.1 here). He wanted to run again and so we did, I think thats when i did one of my best run on the night, he again got a better launch, then by the end of the track i was already ahead of him, he comes back congratulating me and telling me i have a damn sleeper. That was the only cool race. No one else really said anything since no one knew it was turbo lol, after coming back from a run, i would see poeple talk and point at the car, so that was cool too. I am just really hoping for low 13's. and one day a high 12, to make people really talk =)

His 1/8th and 60' was better than mine so it looked like he was going to beat me everytime we raced, but my car really starts moving hard after the 1/8. his time when i ran 13.9:
2.2', 1/8 at 9.0, 1/4 14.1

 

Now that you got your juice hooked up to help you get a better 60 and spool, you should see high 12s to low 13s. Neal, have you been able to find the compressor map?

 

High 12's would be amazing to get!! i'll be very happy if i get at least a 12.9. But the more realistic result might be around 13.4 or so. still acceptable but not good enough. Maybe ill get more serious and start doing some weight reduction, at least take out passenger and rear seats or something.

Also, I believe I now know why my launch seems to lag a bit and why I cant do better than 2.3. I logged my a/f just from a stop to 3k, and my a/f was in the 11's, which is very rich at such low RPM's. I made some corrections and brought it up to mid 13's since there is no boost there i can run leaner. It does feel a bit better off the line. But either way, im still going to spray off the line =).

 

bahahahahha, jezzzz!!!!! so freakin cool! take off on a XX shot, smoke up the tires like my 5spd, then the nitrous turns off when boost comes in and omg wow, lol. It felt great!!! Mid to low 13s streetz, no excuse, I say you just go for a few gallons of race gas and just spray the whole powerband FTMFW

 

Have you tried a little bit higher in the 13's for the A/F below 3k.. like a 13.7

 

^ ^ ^

Sunoco 104 or VP Racing Street Blaze 103 - either will protect my 3.0 under plug-melting temps and pressures caused by 150-shot of nitrous. I betcha it will let you run all-out at the quarter mile.

But you'll need great tires.... Daymn, I'd like to see that.

 

Do I smell a trip to Miami? lolz

 

That's a long drive -and a longer tow...... Probably not - unless I get to drive

 

Bottle warmer installed. IM BACK IN THE NITROUS GAME.

So now you've got turbo AND nitrous cards to deal at the track. Get that race fuel next, then go forth and kick azz.....

And take videos.

 

[QUOTE=grey99max]He doesn't need race fuel. He is perfectly cool with 93 octane.

 

[QUOTE=SonicDust187]You have car insurance, right? Race fuel is insurance for your racing engine.

You might not ever think you need car insurance, but you need it for various reasons.

Race fuel prevents preignition/detonation, common problems with boost and spray. You can raise boost or raise shot-levels and be safer.

"Use it and don't lose it" is my motto. Experience is a wonderful teacher.

 

If those IATs are accurate (who knows, if it's the stock IAT sensor) and he's going to be spraying now too and is not pulling any timing I'd DEFINATELY be putting race gas in that thing.
