Project 2JZ goes to the drags!
|

Hi all,
I finally got around to taking my Supra to the drags yesterday (Willowbank). It's now running ~18psi boost with a fuel cut defender and a bleed valve, so it feels goddamn fast on the street. I just wanted to find out exactly how fast! The power to weight ratio suggests a 12 second pass, depending on traction and driver ability. 
Anyway it was a busy meet so I only got two runs in before I gave up and went home. The first run I bogged down badly and hit the rev limiter a couple of times, but the raw horsepower saved me from too much embarassment - 12.997 at 114mph. Just scraped into the 12's, woohoo! Needless to say I was very impressed that the car ran a time like that even after I botched it so badly.
The second time around was much better - I used a lot more revs off the line, and kept a better eye on the tacho. I had to back off a bit in second as it started axle tramping, but apart from that it was a near perfect run. I recorded a 12.49 at 117mph! Pretty damn impressive stuff considering I'm running the standard engine, turbos and ECU. I can't help thinking how easy it would be to get into the 10's (big single and management should do it), but that's a lot of money...
So there you have it, I've proven that I have a 12 second car. I doubt I'll take it to the drags again though, I just did it out of curiosity. Next on the upgrade list is a torsen LSD, suspension and brakes. Methinks the engine has been upgraded enough already.
Oh yeah, I should have pics and vids soon. It looks pretty funny bouncing down the strip!

Very nice work. Congrats to the fruits of your labour!
In regards to your how easy to get into the 10 second bracket comment, I think you'll find that it is more suspension, driveline and traction work that would be needed over huge amounts more power.
If you sorted out the rear end I think you could probably run a high 11 with your current state of tune.
But, you don't want a car that is only good on a straight. Wheres the fun in that?
Question:
Where you, runing street tyres?
If so that is pretty damn awesome! (not that it isn't if you were running slicks)

The funny thing is that the way it looks on the video is EXACTLY how it feels from inside!
The run was on street tyres, as suggested by the big mph and the relatively high ET. There are easy low 12's in the car as-is with a bit more practice... slicks and race fuel are for cheats.
Good to prove the point with some big MPH... although 18 months is a long engine conversion!

Good one Norbie, that there is an impressive time. The MPH suggests that 11's are not out of reach.
10's will definitely require both good set up and huge power (but you've got a 2JZ which is the best starting point to big HP)
Some say that slicks and race fuel are for cheats - the same thing was said for turbos a while back- Why is it that people say that slicks are for cheats and then go on to quote how quick a car may have been with slicks?
I say that you run what you run, and if you pay the dough for tyres and fuel, good luck to you.
Well done again Norbie, we all know how much work goes into these conversions.
Note to self - Must get a 2J mmmmm.

YellowRolla: I think it was more the fact people say thier "Street Car" pulls 10's using C16 and slicks with a shot of NOS when infact as soon as you use something that is not legal on the street it's not a street car. Turbos are legal on the street. Slicks are not.
I just think it erks some people that some people claim there car is a fast street car but need race car level non street stuff to get that time.

I assume this wasn't directed at me, as I made no mention of going faster on slicks, but do I feel obliged to respond.
I am one of those people that think slicks are 'cheating'... if you have a street car you run street tyres until it becomes impractical to do so (ie. car becomes dangerous or pointless without them, probably about the mid 11sec/125mph mark on street tyres in most cases).
It's almost like breast implants or standing on your tiptoes... you are but you're not. It's a sense of falsity.
However, the reason people say this and then make comment on how much better a car would be with slicks is to put things into perspective. Compare apples with apples, as it were.

I agree, quoting your car to be as quick on the street as it is on the strip is not a real comparison, but you quickly learn to discredit those who are all too keen to quote 1/4 mile times in various situations (strip, gtech, stopwatch, slicks, no slicks etc.) as being the be all and end all of any comparison between cars. As so many have said, "when the flag drops, the bullshit stops". No one is really impressed by what you tell them your car could have done, it all comes down to how you run on the day, head to head with a competitor. Same goes for dyno comps. Excuses are just that.
Why are slicks at the track a problem? Just as slicks are not street legal, so is removing your spare wheel, or increasing boost, or having a car over the legal noise limit............Not to mention that there aint no traction compound applied to your average strip of tar past McDonalds So how far do you go with calling anything "street legal?"

Wastegate, if you up the boost on your street car then it is technically no longer "legal" as it is illegal to play with the wastegate at all.

Only half true, if the raise in boost pressure causes the car to run bad emissions then yes, it's not the boost that is illegal it is emissions. If you can raise the boost and stay within legal emission output them it is legal.

This thread is for Norbie's car's performance - a VERY quick car it is too!
So much to be said about the differences. I think that we should add any further comments about tyres to a new thread in the outhouse.
GT - I am not offended and I don't imagine that anyone is.
Norbie, don't forget to scan your timeslip and send it to the board so that the records page may be updated and you may take your rightful place as the >1.8L FI record holder.

'Not going out again' I hear you say!? Look at the mph-116. That has 11 seconds written all over it. Nice hard springs and shocks to try and stop the squat with some sticky tyres at a low pressure to give you the grip and you'd crap it in! Mind you, with a bit of work you'd have a very nice car for some hillclimbing or the occasional sprint round a track.
Good to see a project come to fruition mate. I'm planning to have the blue whale on the dyno august 8. Hopefully I'll have a track time to post in the near future as well.
Enjoy

Soft springs and lots of squat are exactly what you want for the drags - it maximises weight transfer to the rear wheels, thus increasing grip. Have a look at any serious drag car and you'll see they're set up with very soft rear suspension. Hard springs are for circuit racers, not drag racers!
11's certainly are possible with better tyres and a working LSD (mine is pretty much a single-spinner now). As I've said before, I'm not looking to do a better time for fear of breaking something! It would be cool to do an 11, but not while the car is my daily driver.
Pete: As GT pointed out, terminal speed was actually 187 so I was well into 4th gear, in fact I think I hit the rev limiter just after I crossed the line. Remember I have pretty low gearing (4.1:1)... chances are you wouldn't hit 4th in your car since you have more revs to play with and taller gearing.
You certainly do lose time changing gears, so if you find yourself at the top of 3rd just before the finish line it may be worthwhile to just let it bounce off the rev limiter instead of changing into 4th. It's one of those things you'd have to try back-to-back to see what works best.

Sorry mate read it wrong. 187 (thanks GT).
Same deal though, with rev limiter in 4th.
Norbie, thanks, you answered my question well. As for my car with longer gearing: when my car was on the dyno, I saw a reading of 183 I think, and that would've been over 7k in 4th, so I wouldn't need to shift to 5th as I don't think I'd get to 187km/hr.
Good timing if you hit the rev limiter just after the finish line!
I need to find a place where I can get some practise launching. Its interesting about soft suspension being better for drags. With the tems in my car I could do some comparisons. Need another day like at dubbo.

Unfortunately IRS works against you at the drags.
Lots of squat induces large amounts of negative camber on the rear wheels. Contact patch goes to the shitter and you have traction issues.
It's going to be a balance between squat and negative camber. Harder springs may possibly help in this situation. All trial and error.

I should elaborate-hard springs are to stop the IRS squatting. in a solid axle car squat is desireable-in an IRS car, because of the camber issue, it is not. Hard springs help this. Hence the extra soft tyres to counteract the hard springs...But then again-it's not a drag car anyway....Fun, fun, fun, fun, fun, fun, fun, fun, fun, fun, fun, fun, fun.

Hmmmm....in regards to slicks
When comparing Slicks with normal street tyres with tread,
is the only difference between the 2 that theres more tyre on the ground with slicks ? more surface area ?
So would it have the same effect to just put wider street tyres on ?
hence....same effect as having slicks on yet street legal
or is there more to it than just SA

mani: Yeah there is more to it, including the tyre rubber compound, softer rubber in the slick, they are designed to be "warmed up" as most street tyres if you do a burnout on them will grease up and infact hurt your traction. There is also the side wall, the slick has a thin and less support sidewall that acts like a rubberband.

Difficult, but not impossible! A friend of mine has a very quick series 3 RX7 which ran consistent 11's in full street trim, with circuit-oriented suspension and street-legal tyres! It's now doing low 10's with drag slicks, same suspension setup and still untubbed.
I'd be pretty impressed if I could get my car to that level; reel off a 10 second pass at Willowbank, change the tyres, drive down the road and start cutting hot laps at QR!

the 147kph is half track, so basically the car does 0-147k in 8.2 secs, my corona is at 80k by then
