Nitrous on a junkyard 3.1

[Superdave]

According to the bin file.. if you can trick the CTS to make it think the engine temp is about 120c (about 250F) then the ECM will pull 3.16 degrees of timing. That should help.


No guarantees though..

Muchos Gracias, Superdave ... I shall ask my Megasquirt-building buddy to look at that chart and hope it makes some sense to him!

so how much are you planning on shooting? 100 +? i just started using my mainline nx kit, and it specifically states ..." provided that your vehicle has the sufficient, fuel metering, fuel flow, fuel pressure required, as well as the neccessary octane fuel to prevent detonation, the timing should not need to be changed for any jet size..." only for OPTIMAL performance, not neccessarily a "must". hope that helps, good juicing!

Was planning on a 150 shot ... as I happen to have the jets, and am not too worried about the survival of the engine! We shall see ...

Is it possible to video this and put it on youtube?

I saw a kid blow a rod out the bottom of his oil pan on an Evo, he wasn't spraying, but did didn't quite understand what that red line meant on the tach, but he found out after he when 500 past it

Hi folks. For what it's worth, I took the car down the track at the weekend. Previous best was a 17.3, in a partially stripped, pure stock 3.1 four-door GP. In a fully-stripped car with no catalytic convertor, and fresh 5w30 fully-synthetic, it was running 16.8 all day. Then I did a run without the fan belt and it dropped to 16.3 at 81.81mph! Might not bother with the nitrous after all - I swore there was a 15 in this car, and I reckon I might get there without gas! I've already started cutting the side-impact bars out of the doors....

if you do spray... you can also add fuel threw the nitrous kit. just put a larger fuel jet in and walla more fuel... no need for a FPR.
