Lesson 342 – Ask advice when you can
Last year we had some powerband issues. That is to say we had a lot of power, not really applied where we need it in the car. We weren’t going to pass by the opportunity to get some advice from AMS while we were there. So we drilled around for questions, asking the Turbo guru and Eric, the sales manager for some advice.
Here we discuss the turbo itself, and how it is scaled into the car itself. Granted we are back on the L1R turbo and the main focal discussion is getting the powerband down, lower in the RPM range.
Being on a budget, and not particularly having anybody step forward with another setup to run, we will probably be looking to decrease Tim’s intake manifold back to stock with a mild porting job as a first step. We are also considering a smaller intercooler to address turbo response AND cool air to the radiator. While we didn’t overheat on One Lap, Tim has been able to get the car warmer than expected running it hard at Watkins Glen.
We did get the close up introduction to the AMS 750R turbo they released in June. It sparked a good debate on the leading fin edge, which up until this point was thought to be crucial in designing it with a knife edge, not a the machined groves.
