AIR Street Meet 5th April - who's running?

[whatsisname]

Well after much research I've actually decided against the lightweight flywheel. I'm glad you started this whole flywheel issue up Brad!

I've spoken to a number of people in the business of street drag style cars, & I've also read up a bit more on various internet sites. Even Tim (ex RPM owner/ horsepowerinabox head honcho) suggested I stick with the stock flywheel weight.

Here's how it was explained to me - The engine starts @ high rpm for the launch in a drag run & doesn't drop more than ~2000rpm throughout the run. This means that the quicker reving light flywheel doesn't really come into play anyway as you're already @ rev's on launch & will remain at high rev's. The gains in quicker response are counted by the faster drop in rev's on gear changes. The light flywheel also means the "perfect launch" becomes harder to achieve as the rev's will drop quicker making the likelyhood of bogging increase.

The above probably isn't worded all that well but hopefully it makes some sense?

For track racing & general street use I believe the gains in response are well worth fitting a light weight f/wheel, but if quick ET's are you're goal then the torque benefits of the heavier f/wheel on launch are of more use.

i'm in put me down for two car positions

what time and date

[GTR King]

Hes spot on about the standard weight flywheel. Most drag racing ppl would tell u the same. Lightened flywheels r for street and mallala. As he said the revs r up from the word go and u wouldnt drop more than 2000rpm between gears so it makes sense. btw make sure u get flywheel balanced with the new clutch and mark its position. Otherwise u might get some bad vibrations :[

[whatsisname]

Yep mate clutch & flywheel will be balanced.

Are ya' bringin' the beast down for a run (& to kick my arse)?

[GTR King]

not until im back at work as i can afford it. I need to buy some tyres for it is the main reason and i dont wanna bang the wall. Its bad enough even with good race tyres. Sooner or later i will tho :]

[whatsisname]

Bummer Oh well maybe you could lend John a hand & drive one of the GT-R's for him

[GTR King]

I would if asked but thats his call, I would be honoured actually. Then again i dont wanna blow him off, he might not like that :]

hehe

[EnricoPalazzo]

As long as u can keep in boost range whilst chaning gears, then the lightned flywheels will be heaps good advantage as faster reving, althou u will drop revs quicker aswell.

I had lengthy conversations with a quite a few "players" in the street car drag scene. ALL of them gave me the same advice - stick with the stock weight flywheel. I think that says something! A number of respectable performance flywheel manufacturers also said the same thing. These people "could" have made an easy sale by telling me "yeah it'll make a huge difference" but they told me what they honestly believed.

*Remember - this is looking at it from a pure street car drag perspective*

I put the money saved on not getting the light f/wheel towards a 2 line handset for my Microtech (wanted some real time engine stat's without having to hook up the laptop) I might install a shift light too?

mmm drags

me be there - doubt skyline will be ready so i'll be a spectator

What are you having done to your 32 Mel? Why is it off the road for so long?

[2.5]

whatsisname if your really pulling 257rwk on 13psi and you can only run a 13sec 1/4 mile

aren't you ashamed of your car's lack of performance, my car car is being built up to make 330rwk on 20 psi but prior i made 260rwk and i ran a 11.3 1/4 mile maybe you should check who's dyno your using sounds like your figures and math just dont calculate .

I actually couldn't give a rats arse what rwkw figure my car makes to be honest. I merely add this info in my sig' as a reference to MY latest efforts. Be they 1/4 or dyno related.

I agree whole heartedly with you that my ET is shit considering the rwkw reading (that's what the dyno spat out & that's what boost it was running) but do you really think that just off 116mph TS on a 2.667 60ft is a good indictation that 13's are the MAXIMUM potential of my car? I've had runs vs cars that have pulled low 12's or even dipped into the high 11's yet the TS isn't much higher than mine. Doesn't take a brain surgeon to figure out how good they 60ft'ed!

The 1/4 passes in my sig' were run on 17' road tyres & with a badly slipping clutch. In fact I had to drive off the line @ 3000rpm. Anymore rev's & the clutch simply let go causing the engine hit the limiter. My car is by no means a drag car.

When I have drag raced my car I've done it every day trim. Nothing is removed not even the spare & wheel jack. I don't drop my tyre pressures @ all (32psi) In short, I simply hop in the car, head to the servo, fill up & run it as is. Why do I do things this way? Because I can. At the end of the day my rwkw reading may well be seriously inflated - if it bothers you that much I can certainly remove the reference to it in my sig'.

Good on you for running 11.3 with 260rwkw, & goodluck with 330rwkw on 20psi. I'm happy for you.

Out of interest what set-up did you run your 11.3 on? As in what tyres did you use, what gearing -auto/manual, what fuel & so on... What was the 60ft & TS on your 11.3 with 260rwkw pass? Oh & which track?

Cheers,

Matt

good response .... we 'old members' wub joo Matt .... I'm sure when u get it all together next weekend you will be doing very low 12s and hopefully even break into the 11s! Hope your clutch is good .... got my beast back today and the clutch is excellent (for a single plater) .... I have nearly stalled it a bunch of times already though!

It's gonna be a nice cool night for the cruise and no rain in sight (at this stage). EVERYONE better be there!!!

So have we decided on a definite meeting point?

You can bring as many cars as you like. The time & date - Time: starts @ 4pm, racing from 5pm till 10.30ish Date - ummm... did you read the thread topic?

[whatsisname]

Awwww shucks...... right back at ya' big fella. I loves ya's all

I'll be happy with anything in the 12's

Yeah I've got my clutch sitting in the garage. Fitting it Friday. I ended up going with a single plate too - 9 puck cushion button ceramic & 2400lbs pressure plate. Nothing too Xtreme Fitted a Pivot shift light tonight too. Works well The final latest addition was suppose to arrive today (friday now ) A 2 line handset for the LT12, so I can have all the basic engine info at hand all the time. Should be interesting to see how effective the FMIC is at dropping inlet temps before & after the run?

You shouldn't have any worries bedding that clutch in before the 5th mate. Just don't wear it out before hand

Yeah... we dont care if your car runs a 28.5 down the quarter mile whatsisname .. we love ya...

bah to 2.5 (newbie!)

OMG.. NOOOOOOOO the drags are on the 5th right?? damn damn damn, i got a wedding to go to that day/night.. and its IMPOSSIBLE to get out of.

/me wipes tear from eye....

[whatsisname]

Thanks Cheeky

Wedding or the drags? Go the wedding!
