Mine squeaks, sounds kinda like wet tennis shoes on waxed vinyl tile floor when mashing the pedal, I don't usually hear it when I'm driving [ Boomer Hearing ] but my in car cam picks it up. .

I have plenty of time slips that show removing the carbon traps resulted in Zero gains on my car at the drag strip. The S650 is trapping nearly 2mph more on the 1/4 with 20 more HP, One would expect nearly 1-mph gain on the 1/4 with 10hp+. Didn't happen. ./

I'll keep the S650 intake and give up a few hundred rpm and save the $2,000+ that CJ setup costs for something else. Wengerd dyno .... I'd surmise tuning could get power to carry out to 8000.

Based on the 650 intake testing Wengerd did on the S550, the S650 intake looks to have a power curve similar to the GT350 intake, so no reason to swap. These S650 will easily run 10's NA with some Corn Fed RPM's ... ./

And it's seriously unlikely Ford will raise the shift points to 7800 which would really get these S650 flying. .

Crazy, A similar car in the US would be 71 ....

Yes, what you are seeing is normal. Ford has been using 'smart charging' for years, it's supposed to increase fuel mileage by reducing parasitic drag from the alternator by not charging under load, and then does regenerative charging while coasting and cruising, .

It's page 303 in the Maintenance Section of the Owners Manual .

The owners manual sez, 1qt coolant loss a month is Normal.. --If you have to add more than 1.1 qt (1 L) of engine coolant per month, have your vehicle checked as soon as possible.-- I don't agree loosing 1qt a month is acceptable either, there's leak IMVHO. I've got 20K miles on mine and the...

Ford is using E10 stoich 14.08 as the reference for the AFR reading, So 13.9 - 14.1 at idle, cruising and part throttle is normal. .

I guess it depends on your definition of 'practical' ... Track only use it's practical, Street use, not so much. Plus, Nitrous has gotten Expensive over the last few years, it's $7lb around me, luckily it's only 7miles to the shop for the refill. I installed a single nozzle in intake tube on...

I told myself I would ignor this thread but, Seriously, 10pages long and 1/2 are you complaining ... Give it a rest already. The S650 and whatever facelifts it'll get, will run til 2029 so either buy one or don't ... ./

Not sure what your question is, But, Yes the car falls flat if you tag the 7500rpm limiter. .

There's no info on PC S650;s, Closest I've seen so far is Ford Muscle mag has an install article but waiting for them to post results ...

Kinda weird F21 is shown as a spare and has a fuse on it. F8 is a 15a fuse , It's Hot on Start/Run , Looks like the safest to use and uses the add-a-circuit from Whipple. .

This, My 2018 Gen3 had way too much iron on the paint to use a microfibre, I used the Mothers clay bar to pull it off. My S650 OToH had no iron on it, It did appear the dealer detailed it while they had it as it shed water like it had some kinda wax job and the orange peel was noticeably...

2024 Mustang Gets A ProCharger P-1X

The airbag fault/dash alert has always cleared when I put the seat back in. .

The cat temp is an inferred temperature based on load, timing, rpm and other parameters. I'm catless and logged inferred cat temps of 1680f WOT ... You can go on the 6G forum and search for a thread by engineermike where he's tested exhaust pressure and temps. ./
