Nice setup. I like the Motec.

 

wow great work..

 

Looks good man.

People will notice that Motec people are Motec people for life and wouldn't use anything else. Once you know and understand Motec and realize it's capabilities, you realize how amazing the stuff is. It's 'expensive' relative to the cheap stuff out there, but worth every penny.

I have pretty much all the same stuff in my race car but I opted to go with 2 dual LTC's and 4 LSU 4.9 sensors, 1 per cylinder instead of EGT's.

I think once you get a chance to play with the knock module you'll be sold on it too.

 

I'm already sold on it believe me unfortunately I have a tranny that needs my attention errr I mean wallet right now. Besides my engine is stock as it sits and I plan on building it I don't need the knock module to protect a stock engine it's going to let go knock or not. I also blend my own fuel and it is virtually knock proof at these power levels. I have had the knock box on there but its a waste of time I have taken the timing 5* past MBT just out of curiosity and it doesn't knock so as of now I would be wasting my money.

I thought about the individual widebands but wanted to see what kind of temps I was looking at right there anyway and I wasn't sure how long they would last.

What kind of power are you making and do you have EGTs (how high are they)? How long have the lambda sensors lasted with what kind of driving? I'm only asking because if they have lasted a while and seem to hold up to the heat I would consider it.

 

I like the setup momentum although i am not a fan of the turbonetics lineup. Did you make the exhaust and intake manifold yourself?

Wish i had the money for motec.

Tonys race car is setup top notch. Makes 1000ish whp id imagine as it traps 170+mph in the 1/4 mile.

 

Yeah I made the whole setup. If you have the money for a turbokit you have the money for a motec most people just spend their money backwards (just my opinion not trying to start a war).

Before I changed to a cold air intake when my car was bone stock I bought an M800 and made a PnP harness for it.

If it's a drag car the sensor life question isn't really valid as the duty on the road course is significantely higher although I'd be interested in knowing how long they last and what the EGTs and EMAP readings are during a run.

 

If you are using exposed tip EGT's they will not last long according to Exhaust Gas Technologies where I bought mine. They estimate a season of Drag racing so I plan on running mine during tuning and that is it. I figured that I would throw them in every 3-5K which is about a year and check to make sure there has been no changes. Mine have a 1/8 NTP fitting so I can use pipe plugs while they are not being used or for testing the manifold pressure.

 

The LTC's use the LSU 4.9 sensors. They are good to 930C under regular operating conditions and 1030C max. I have never measured EGT's on my car, never cared much as 1 EGT reading is about worthless as far as i'm concerned. 4 is obviously a different story.

I have the lambda pressure comp data, so the data will still be correct in the pressurized manifold.

It's a drag car that doesn't run very long and only sees the track, so I hope to get a fair amount of life out of them. Only time will tell. It makes about 950whp and at 410kpa the emap is around 380kpa, pretty good size turbo and exhaust setup.

 

So how much fuel did you add to cylinder 4?

 

I don't use exsposed egt's the enclosed ones react faster than you would expect and the delay is very easy to compensate for

As for cylinder 4 it's not as simple as you might think I add an remove fuel from every cylinder under different conditions all said number 4 runs cooler than the rest under wot and high rpm

I'd be curious if tony finds the same with his car although being a drag car I guess it's wot high rpm only so maybe less noticable
