Re: LTG ecotec engine wiring help needed

The VSS signal is very easy to manipulate. You splice the crank signal and feed a Dakota Digital SGI-5. Then feed the ECM with the Output of the SGI. You adjust (divide) the signal in the SGI so you get a 0-5mph feed when engine is idle... I read about near 0 mph at idle and it tops out ~20mph which...

Re: spray mixture

buy the cheap laundry detergent which is biodegradable like XTRA or usually the store brand. Its nice to get a blast of clean mountain freshness when driving around in the funky marsh anyway.

Ill usually mix it to like 10:1 - 5 gal water to 2 qt soap

Re: 4cyl Ecoturd now in Silverado

all factory tunes are TQ limited. (transmission life extending) all these turbo motors can make much larger TQ numbers and have more of a curve than an flat line... if the heads can flow the air the turbo can be tuned to run outta breath. GM limits airflow to make those nice flat TQ curves they disp...

hey ladyblackwater... can you read... it makes more TQ than the 5.3 Gen 4 and Gen 5 on 87... put 93 or E85 and you will even surpass it more. Also I agree with you to a point... if all you can work on is a carburetor and you have to bring your vehicle to a dealer just to diagnose an issue they maybe...

Re: 4cyl Ecoturd now in Silverado

2.7T will swing bigger prop than Gen 4 or Gen 5 5.3L... just saying... under the curve 2.7L makes more HP.

at 3000 its only about 50HP lower than stock Gen 5 6.2L L86... lots of potential

Re: 4cyl Ecoturd now in Silverado

I highly suspect this motor will become the fleet vehicle motor of choice vs the v6. So availability in the aftermarket come 2020 or 2021 will be surprising. I am an EcoTurd fan though and share Russ's opinions bc I know what these motora are capable of doing. I can turn props designed for twice the...

Re: 4cyl Ecoturd now in Silverado

Yes... saw it just the other day... that 2.7 looks promising... but

Delete the DFM
the 10:1 is a bit high so may not have much to gain over stock boost levels.

Re: Quick connect for airboat flag

Yep we try to only run our lighted whips when running switch cane and tall trails. Public waterways its nav lights only. We only run headlights and LEDs when not in the main channel to help navigate. Any light other than nav lights on the main channel will get you a ticket here in LA and TX.

Re: radiator distance from prop

my recommendation before you start moving things around, call Turnkey and ask details. that is a great group of folks. as stated LS and Ecotec motors that run on modern ECUs and EFI run 180-210 easily without issue. doesnt matter is its modded or not... if the ecu is controlling temps then you will ...

Re: radiator distance from prop

Honestly 195F is a good number if you ask me! Radiator is where it is supposed to be. I dont like motors that run too cool because that just creates condensation potential in the oil side.

I'm bias a bit though... I have an e-stat that maintains about 200F-210F running temps.

Re: 502 power VS torque

What I have found through many discussions is that it isn't really the large prop vs small prop... its actually air flow to the prop. Larger props move the location of grabbed air further way from all the rigging and crap that can restrict flow from getting to the prop and essentially loading the bl...

Re: 502 power VS torque

according to the dyno sheet referenced you are still climbing in HP even out to 6300 so you are leaving some power and therefore thrust on the table... but the difference since the sheet stops at 6300 is only 25HP+/- there may be more past that... cant tell unless it was dyno'd out there. Should the...

I have read every post... this is all hilarious! Here is how you solve the problem... 1.
