90mm pulley was used to run the 10.81 with a DA of about 1800. It is about the smallest you can run safely with the stock HPDI fuel pump and good fuel. The car made 610 RWHP with this configuration.
We are now running the Magnuson HPDI pump which has approximately 30% more flow than the stock pump. With this pump I have used an 85mm pulley and have made 630 RWHP but due to the DA at the track I haven't run any faster yet.
Heading back to the track on the first week of December with a couple more mods and looking for a bit cooler weather for some faster times
