cheekymonkey Posted March 23, 2009 Share Posted March 23, 2009 Arrggh! Went to chav-central fast show at santa pod yesterday, for my first session for 6 months or so. Only had 3 runs but this was the 3rd session in a row where I have been spectacularly disappointed in my runs. Now, at Supra Pod 2007 I had a brilliant time, and was consistently hitting mid 13s or lower with a best time of 13.066 on the day. This was with a bone stock car with the boost controller turned up to 1.2 bar. Since then my car has had:- - 650cc injectors - PowerFC and map by Ryan - Loads of suspension bits - gauges etc to safely do BPU - new SMIC - RLTC - Line lock However no matter what I try I keep getting sodding low 14s and if I'm very lucky high 13s. It's embarrassing! The first time I went on the strip after adding all my gadgets I didn't do very well, and put it down to gadget overload. I was trying to use the line lock kit, and RLTC launch control and didn't really know what I was doing, and 3 runs isn't enough to play and practise. Yesterday, I turned RLTC off an forgot about the line lock kit completely to try and go back to basics. My first launch was crap and the car juddered (14.1). Second launch was smoother but just not fast enough, again 14.1. 3rd launch I though went really well until I was told it was a sodding 14.2! My car has more than enough power and I can't see what else I can do, apart from more and more practise but it's very hard with only 3 runs and many different variables. Suspension set up wrong? Too much torque / not enough traction? Me just being crap? Sorry for the rant but I hope some of you may have some ideas Quote Link to comment Share on other sites More sharing options...

mr lover Posted March 23, 2009 Share Posted March 23, 2009 I ran at Suprapod in ttc setup twice and then changed back and was consistantly 0.7 - 0.8 secs quicker, I am auto though Quote Link to comment Share on other sites More sharing options...
cheekymonkey Posted March 23, 2009 Author Share Posted March 23, 2009 crap tyres? Don't think so - I've had Eagle F1s on all the time, although they are the newer Asymmetric ones now. Quote Link to comment Share on other sites More sharing options...

cheekymonkey Posted March 23, 2009 Author Share Posted March 23, 2009 What suspension are you running with? Yellow bilsteins with CW springs. Not sure what my Geo is set up as though, but it's not specifically set up for drag, and I probably wouldn't want it to be either. I do track too Quote Link to comment Share on other sites More sharing options...

cheekymonkey Posted March 23, 2009 Author Share Posted March 23, 2009 What was your 60ft times? 2.57, 2.63, 2.68 Looking back at Supra pod... ok randon sample 2.24, 2.54,2,18 So yeah looks like my launches are crap. Are there any sites that let you enter all the numbers and compare timeslips? Quote Link to comment Share on other sites More sharing options...
Scott Posted March 23, 2009 Share Posted March 23, 2009 The tyres could be making a big difference. Quote Link to comment Share on other sites More sharing options...
Tom Posted March 23, 2009 Share Posted March 23, 2009 fit drag tyres and you'll probably see 12's I'm no expert but drag tyres are for drag and street tyres are for the street Quote Link to comment Share on other sites More sharing options...
AJI Posted March 23, 2009 Share Posted March 23, 2009 do you have adjustable suspension? Getting as much weight to transfer over the back wheels evenly is important for launching. The new Eagle asymetrics should be good enough once up to temperature. Maybe give a longer burn out before launch? Also play around with tyre pressures. You may have too much or too little pressure for your 'perfect' launch. Quote Link to comment Share on other sites More sharing options...
colsoop Posted March 23, 2009 Share Posted March 23, 2009 Supra pod they actually prepped the track properly. I suspect for chav fest they didn't hence the crap times. what were your 60ft times from supra pod and from chav fest ? Quote Link to comment Share on other sites More sharing options...
cheekymonkey Posted March 23, 2009 Author Share Posted March 23, 2009 hey guys, thanks for the tips. May have to get some drag tyres for next time, got to be worth a try anyway! Of course I was still faster than most there yesterday, there were even some cars in the mid 19s *grin* Day was good and managed a nice shot of the jet car with my little point and shoot.

cheekymonkey Posted March 23, 2009 Author Share Posted March 23, 2009 (edited) Have just posted some vids of my runs, from inside the car - so you can hear what's going on and when the tyres slip etc. 1 - No gadgets, 1.1 bar, 14.1 sec 2 - No gadgets, 1.1 bar, tried to make the launch smoother. Less juddering but slow start. 14.1 sec 3 - RLTC in use - set to 16% (figure pulled from my ass) and Launch control with revs set at 3400rpm. May be a bit too low as launch again seemed slow. 1.2 bar this time. 14.2 sec If anyone has time to look and comment that would be great. Am thinking it's a combination of lack of practise and cold tyres. I've lost the detachable controller to my line-lock kit so my burnouts were pathetic Edited March 23, 2009 by cheekymonkey (see edit history) Quote Link to comment Share on other sites More sharing options...
Branners Posted March 23, 2009 Share Posted March 23, 2009 I dont think i have ever seen RLTC help at Pod. Its generally a hinderance. It also needs to be 20% slip for the ultimate launch (Terminator may be able to elaborate as to why). This early in the season the surface will still be seriously cold. The ground is still in winter temperatures and so the Pod surface wont have heated up yet. Run the same car in June under the same spec and you will be quicker.

supradriver Posted March 23, 2009 Share Posted March 23, 2009 lol you did better than me. i was only getting mid 14s and yet i was getting them times on a wet track. maybe on a warmer track as branners has said. i was hoping for better times.

Tom Posted March 23, 2009 Share Posted March 23, 2009 (edited) what was you up against in the first vid? I liked how as soon as you were in 3rd you pulling hard against it btw do they measure from when it goes green or when you leave the line at pod? as your reactions looked pretty bad and it didnt sound like you went anywhere near redline in 1st gear on the first run. Also I can hear lots of wheel spin and wheel hop and your burnout in one of the vids was waaaaaay too short and turn you tc off on the plus side your gear changes are nice and quick Edited March 23, 2009 by Tom (see edit history) Quote Link to comment Share on other sites More sharing options...

cheekymonkey Posted March 23, 2009 Author Share Posted March 23, 2009 what was you up against in the first vid? I liked how as soon as you were in 3rd you pulling hard against it hehe that was my mate's GT4 - he was Well Chuffed that he was ahead of me for a while there. He's running 290bhp and to be fair he keep up with me on the road, great car. He got off the line a lot quicker, but got a 14.7 which aint too bad for his car. btw do they measure from when it goes green or when you leave the line at pod? as your reactions looked pretty bad Yep it's only started when you start moving. I knew reaction times didn't really count so I was purposely not rushing. and it didnt sound like you went anywhere near redline in 1st gear on the first run. Also I can hear lots of wheel spin and wheel hop and your burnout in one of the vids was waaaaaay too short and turn you tc off on the plus side your gear changes are nice and quick Cheers for the comments - first run was atrocious but the problem is I kept trying to improve but my times were getting worse Quote Link to comment Share on other sites More sharing options...
cheekymonkey Posted June 19, 2011 Author Share Posted June 19, 2011 Slight update guys! I havent been doing much with Supra for ages but managed to get to JapFest this weekend. Had 4 runs today, best time was 12.5 and I even got a 12.9 with a passenger! Mod wise the car was identical to when this thread was started a long time ago, with the exception of the tyres. Am now running Mickey T Street ETs on the rear. Also the following helped: * proper 6-8 second burnout * Launch control working properly * keeping calm on the launches Supra is still suffering with high air intake temps so that is the next thing to hit. Thanks to all who advised better tyres, what a difference. Quote Link to comment Share on other sites More sharing options...
SilverSoop Posted June 19, 2011 Share Posted June 19, 2011 I've always wanted to run down the pod but was just worried about my turbo's exploding or...worse Quote Link to comment Share on other sites More sharing options...
Guigsy Posted June 19, 2011 Share Posted June 19, 2011 Tre drag strip isn't a place for mechanical sympathy My times vary from high 12 to mid 13's. I have intake temp probs too I'm wondering if taking the headlight out and the front of the airbox off will be of use. Or maybe I'll get a spare airbox front and duct some pipework properly Quote Link to comment Share on other sites More sharing options...
Scott Posted June 19, 2011 Share Posted June 19, 2011 One of the members on here got a mid 12 in their BPU running on 19's with normal road tyres so I reckon you can squeeze some more out of that spec on those tyres. The brand he was running escapes me, I'm thinking Michelin but I can't be sure what he said. Definitely going the right way though, well done Quote Link to comment Share on other sites More sharing options...

I want to be able to consistently get into the lower 12s now, the problem is of course heat soak and high air intake temps. Always an issue!
