I only have a tacho on the wolf but I do have a shift light I didn't bother smsing my results as I didn't get a full pass anyway. First run at the drag strip ever so I was very nervous. Never driven with a helmet on before, never even driven the car with the windows up! I was racing my mates ma70 which has 213rwkw and is manual, it was his first time also. Did a very little skid as it only revs to 2100rpm because of the stock stall converter. Then with all the nerves I totally forgot what I was supposed to do. The time goes so fast. Daniel was already full staged before I even finished doing a skid. So I was a bit rushed. I was trying to make sure it wasn't going to stall which is pretty hard to do when you can barely hear your engine over noisy v8's with no pipes behind you! I was in full stage and then the lights went green, I took off with about 2000rpm and it didn't wheelspin, at this stage I realised that I was meant to be in L when I was actually in D as it changes into 2nd too quickly (before I hit boost) so I put it back into L it made some boost and then I changed and went too far and got D so it went 1st to 3rd and I had to let off for a sec and Daniel went straight past me. Then I was waiting for what seemed like forever watching the boost guage sit at 5psi and then it started to make some good boost by a bit after half track. At this stage I was just thinking that I will just see what my trap speed is. So I wound it out in 3rd and I was reeling Daniel in but it was too late. Final result 17.3@98mph Earlier my dad had asked me what I expected and I said a 17.2 so I wasn't far off So I lined up again. I was racing Daniel again as I wanted a rematch. I wasn't so nervous this time and I knew what I had to do. Daniel was once again in stage very quickly so I thought stuff I am going to take my time and be calm this time. So I went into prestage and waited for a bit pro stock style burndown Went into stage lights go green and I launched a bit better than last time in L this time. Hit boost and I was ready for the L-2 change and I went to change and it just leaned out hardcore? Spiked to 20:1? In second gave it some more and it spiked lean again so I got off it and rolled through. I don't really know what has gone wrong? I tested the air/fuels on launch on Friday and it was a tiny bit lean between 4000 and 5000rpm so I upped the fuel there by about 10%. But the thing was that on Friday after 5000rpm it was well rich at around mid 10's so very safe. And this time it hits boost and just seems like no fuel goes in at all. I had plenty of fuel. I have a bosch 044 pump, 8mm fuel lines, 550cc injectors and standard FPR at the moment. I do have a malpassi which I intend to fit now and see if that changes anything. Strange thing is that it doesn't seem like it is doing it in 3rd gear but that is yet to be fully tested. So that was my night. Best thing about it was that I made it all the way down there and back and the car is still running! [Report message to a moderator]
