[QUOTE="PM-Performance, post: 16216127, member: 176806"] Chopping away at my list of issues after the first passes on the car last night, I realize this car is going to be a little bit of a learning curve for me and dialing it in. 1. What do you guys see with IAT's when you log your passes? I'd say it was mid 70's to low 80 ambiant last night. I have a larger moroso resovoir with straight gold coolant in it and a Afco pro HE with dual fans and I was seeing like low to mid 120's at start and about 150* at the end of the pass. I thought it would have been a bit cooler than that, but. . . I assume I should try to pull out some coolant and mix in some ice between runs and then drain when I leave and put the coolant back in? 2. Does the concensus run a line lock kit? I was having some problems getting heat into the tires while getting foot brake on to hold it. As soon as I did it, I would lose wheel speed too much. Now I do have 20's with DR's so I know that is not helping me. I find that if I just do a burnout with no footbrake, I cannot get enough heat in them and cannot modulate the gas enough. 3. Does anyone use a clutch release valve by chance to give feedback on them? I was looking at a Magnus release valve for when the rest is dialed in to get a consistant low 60'. I just dont have the magic clutch slip technique and always made it up on the big end. Id like to fix that with this device, but not sure how I feel about it yet 4. There there is the dreaded loss of boost I have been battling belt slip and boost loss with this thing. I see a very tiny bit of dust on the front of the blower now after a bunch of pulls, but not significant. I am wondering now if boost loss is attributed to temps? Does that make sense with a PDB? I have an ARS tensioner that really did not do anything for me, I went to an 83.7" Gates RPM belt, have a Metco aux 90 set in the middle and BPS 2.4 upper. Its still just not where it needs to be. Boost will level off in upper gears, but it seems the gear I stab it in, (usually 2nd) it dips down and recovers at higher RPM I know this is alot of data, but looking for some solid advice from guys who been through it dialing in their cars.
