I dicked around for a day trying to make it work and ended up mounting it permanently closed.

Gap your plugs tighter.

https://forums.linkecu.com/topic/9334-tach-signal/From my quick research, you can assign tach output to any AUX output.

Does the G4 not have a tach output?

I don't know about LinkG4 but with the Fueltech it gets the rpm signal from the crank sensor and can output to the oem cluster.

In my opinion the 1g straight cut gears handle RPM better than the helical gears found in the later 4G63's. Here's a log from my car to near 9500rpm, oem 6 bolt pump/straight cut gears and ported oil relief hole, otherwise it would be well in...

^This.Low oil pressure or oil starvation are the most likely culprits. Even on a 1.5-6 60' you can see oil pressure drops on these cars. I have the "kiggly" modded oil pickup tube and always run a QT over the full line on the dipstick and see...

Unless the tensioner was bottomed, you CANNOT put to much tension on the belt. NOT POSSIBLE. The tensioner sets the tension.This was likely lack of oil. Are you logging oil pressure? The oil pump is the first to show signs of distress...

This is the Build Thread for Purple Haze. Reply below.

Oh man, if only we were able to have this build thread posted years ago, it would have been cool AF to follow the progress. Better late than never Albert. Welcome, and thanks for sharing it here, and for the calendar photo submission.

Thanks Chris! You can follow on purplehazeracing420 on instagram. I am going back and posting alot of build photos as well as current photos!

This young guy came up to me last night, asked if he could sit in my race car...so I obliged him

time for an upgrade to Fueltech with built in 7 bar map sensor :p

update. kevin jewer has mentioned to me i have maxed out my map sensor. so boys i think we where making more then 45psi lol

that would be my guess...there's NOTHING there to melt it.

5's in the 1/8 is moving!

update!!! i just went to the local 1/8 track this past weekend with a full nitrous bottle 5.80 in the 1/8th!!!

Use a solenoid just before the nozzle and a pressure sensor on the meth line tied into the idle switch input, use secondary maps as the default and revert to primary when the idle switch looses signal, which are set at much safer values.

RTM Racing has built its reputation based on a few simple truths. One of them is that we ship orders out in a very timely fashion.Under normal circumstances, we have rarely wavered from that truth. However, the last few days have not been...
