t-stat question

[RFMustangGT]

would a 160* t-stat cause pinging? I've just put a set of thumper e7s on, change the fuel filter, new act sensor, cleaned mass air meter and it still pings soo bad. also would bumping the fuel presure up help? right now I think it's already too high. I have it set at around 38psi with the vacume line off. thanks ahead of time.

i don't think a 160 thermostat will cause pinning but its deff to low. Most people go with a 180, it seems to work good for me.

Well, what temps do you run at?

The colder the operating temps, the less likely detonation or preignition are.

What is your timing set at? You set your FP to the stock setting. A slight bump should not hurt anything.

Good luck.

right now it does not go past R on the guage. timing I don't think is past 10*. and the FP is set around 38 with vacum off.

i'd get an autometer water temp gauge they are pretty cheap and so much better. My stock one was reading at the L and the autometer says everything is all good

10*to14* timing is good.has your problem started with the cold weather. a motor running too cool will cause oil and carbon build up, i'd install at least a 180* thermostat.and run some sea foam thru fuel system and intake system stock setting for fuel pressure is 35-40 psi.

I would try removing that Diabo Chip, setting the timing to 10, then taking it for a spin. If thats an off the shelf chip, then its basically doing the electronic version of twisting the dizzy. The e7's aren't very timing friendly. I used to run a JET chip and it would cause pinging if I used gas below 91 grade octane.

I think 160 degrees is too low as well but I have no proof other then what I've read and talked about, so take that as you will.

The 160 stat isn't that great for our cars. The coolant will cycle way too much.

With a bumped timing running premium fuel is required. Just for a test put some octane booster in the tank with 93.

 

[RFMustangGT]

I think in the next day or so I'll go and put the 180 stat in and bump up the FP. I already run 93 as the chip requires it.

 

[bill302]

run some sea foam thru system.

Good stuff on here. Another thought:
If you have Mike's heads, have you asked him for tips?

Good luck.

 

[RFMustangGT]

no but I'm writing an e-mail right now.

like a few others said, i put a 160 t-stat in my gt vert, it wasnt right, so i put the 180 back in, it's just fine now, just my.02

Is it pinging at part throttle accel or WOT?????

 

[RFMustangGT]

it's doing it at 3/4 and WOT.
