So I did some searches on PTE T-stats and found out that they open sooner and stay open longer. Removing more heat from our hot engines is always a good thing, but I'm not understanding why it would be much different than a stock T-stat after about maybe one pass at the track.

I am definitely interested in the mod. Can someone enlighten me on a few points below.

1. Would it potentially drop intake air temps especially with a secondary heat exchanger?

2. Is the mod measurable in terms of HP gains or are we just talking, cooler is always better?

it'll give more consistent power run after run...
can't wait to put mine on...

I have one in my SL55 and the car is definitely less affected by the heat, and gives more consistent power. It was a nice addition, especially in AZ!

Well I'm sold on the PTE T-Stat and about 30 days late on the MBworld group buy back in July, but I'm working on getting one now. I just don't get why it works so well. It seems to me that after one or so 1/4 mile passes, the stock stat would be wide open just like the PTE.

I sent you a PM but to paraphrase briefly for the forum, your understanding is correct: the PTE thermostat helps keep the engine cooler when running partial throttle, not wide open throttle. It won't do much for 1/4 mile times if you hot lap but it will help if you have a cool-down period in between.

Is it the same thermostat for the sl65? And where can i get it?

I have the PTE thermostat, car's temp was perfect. and helps a lot, especially if youre from the middle east!

Not sure, but you could PM Bruce at PTE. His member name is: PTE.

Any one have a diy for changing it? Or where it is located on the engine please

It works ,and Pat is good people ,

This is actually one of the few mods I dont really understand as much. I know a modded tremostat is great esp in hot weather temps, but I heard it can be a pain to start cars when your in areas with cold temps (im in a mixed climate area)
