M M 250 Report post Posted December 10, 2017 (edited) Went to a drag day over the weekend. Finished second in DYO, broke out in the final by 0.6 of a second. Car was running super consistent, I just need to sort an over heating issue when the car is not moving. It starts getting hot when sitting in line and especially during burnout, but once moving it cools back down. Might need a better fan. Set the fastest time so far, 15.75. Not bad I think for a stock M30B35 with 3.07 diff. Edited December 10, 2017 by M M 4 Quote Share this post Link to post Share on other sites

Not bad I think for a stock M30B35 with 3.07 diff. good work , yea replace the viscous with a good used or new one . also has your car got the AUX fan there for the a/c ?? if so change the the temp switch in the radiator to a e36 318ti 318is type that switches it on earlier , so if it gets to 1min past 12oclock it switches on Quote Share this post Link to post Share on other sites

I think it's just not strong enough to cool efficiently. Might be able to squeeze one size larger in. Also your old silver E28 with M88 was there, he was doing high 14s. I reckon he could have gotten more but wasn't pushing it too hard. 1 Quote Share this post Link to post Share on other sites

musccoo 82 Report post Posted December 11, 2017 +1 for an e38 fan. Have one in my turbo e30 keeps things under control nicely, also put one in my e21 for the short time I had it and was mint. Like 20 bucks at zebra haha Quote Share this post Link to post Share on other sites

M M 250 Report post Posted December 11, 2017 (edited) Cool I'll make a trip to Zebra and see what I can find. If I can sort this out then you'll see some good burnouts next time. Edited December 11, 2017 by M M 1 Quote Share this post Link to post Share on other sites
musccoo 82 Report post Posted December 11, 2017 (edited) Maybe, I didn't find it bad, just hack the plastic shroud thingy til it sits nice and drill some misc holes, heres pic from my 21 Make sure to test it at the yard tho, cause they can often not work..
