benm: i was under the impression that in a RWD car you wanna run soft rears to put the weight on the rear tyres when launching so you can get away quick enough.... stiff suspension would just spin and cost time.... can someone elaborate and tell me whether i'm on the right track or not?... (no pun intended)....

Newly built. Twin turbo V8 (not sure what ci)

Did one shakedown pass.... 1.2 sec 60 footer, backed off and coasted over the line for a 10 second pass...

His rear muffler was sparking on the ground when changing into 4th gear doing around 110mph. You can't tell me that is healthy for a quick pass (not that im a pro at drag racing or anything).

I absolutely love the car tho :( :( :(:)

If it's too soft, the car squats and the IRS changes angle and the tyre contact patch is less, therefore less traction.

But too hard in suspension the tyre (sidewall) needs to be the suspension and take the motion, if you don't have enough sidewall, this will lead to wheelspin.

It is an artform, i don't know much about it but i'm trying.

Benny i've showed you a few times how to launch a powerful IRS car before a few times haven't I?

Yeh soft rear susp can help traction off the line, basically inertia moves weight over the rear axle, which increases the friction available.

But i think Bens right, surely there must be such a thing as too soft, as my friend commented, 1-2 & 2-3rd it almost bounces the rear axle off the track :) Shame his wastegate isnt venting to atmosphere, add the aural delight of the T51 high pitch scream

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
