Ok heres the deal, as most of you know I have a 2000 Ford Ranger with a 11:1 523 in it and have been working on the suspension and gearing. The best pass I could get last year was [email protected] which seemed off, well I figured out my converter was giving me 12% slippage. I just removed all the front accessories off the front of the engine and the only thing running off the crank now is the alternator. I have gotten my suspension working properly now so it hooks. Last year if I could get it to stay hooked up average pass was 10.70'[email protected] this is first time out this year and it had a couple [email protected] passes. The converter was reworked and now has 6.38% slippage, I was expecting the ET to go down more and mph to increase to 132 but instead the mph stayed the same and rpm's dropped. It now goes through the traps at 6000 vs. 6300. It was suggested to install 4.10's which may drop the ET but on the other hand when I use a gear ratio calculator it is telling me to go with 3.55's. I have a friend with a pair of 29 inch tires he said I could use which would give me the same effective ratio as going to 3.55's but I really don't like the idea of borrowing someone elses slicks as they are expensive. I need help!
