How much (if any) power can be found by using race gas and adjusting timing with a Vortech setup? I searched, but didn't find anything. I am in the 380-400 hp range on stock internals. I am trying to sqeeze out a little more hp without a rebuild. My other option is a small nitrous shot. Would the race gas be a safer option. (ha if safer is the word to use)

 

I believe if you swap pullies that might be a lil more safer and get you some more power, rather than tuning for 100 or using NOS.

 

race gas is always safer

but is it safer to push the timing to the edge than just upgrading the pulley? hmm i dunno maybe, maybe not

 

i guess I could go to the 2.87. i was just looking for something that could be done on occasion. i know there are several running the 2.87, but are they all on stock internals and do they beat on them regularly?

 

some are on stock internals

think it over carefully as the 2.87 overdrives the blower a little and will actually overdrive the intercooler beyond what it's capable of cooling so you'll be ultimately blowing hotter air into the engine.

We don't know what the rest of your mods are but surely there's something else that can be upgraded besides running race gas or the 2.87

might stay tuned for using the 2.87 with a wastegate or aftermarket bypass valve to give you more low/midrange power

 

My answer was vague but your right its the timing advance that might be more harmful. Surely theres something more he can run, cuz several of my friends have well over 400whp and they have usually 3.x something pulley, cams, headers, sometimes test pipes and exhaust.

 

i'm getting ballpark in the 450whp range

if you already have headers, high flow cats, exhaust, plenum/manifold, then look into getting the KJR crank pulley, cams, 3.12 pulley if you're not running it (assuming you are) and the 3.9 final drive. None of that is as cheap as getting the 2.87 pulley, but understand the new found heat you'll be seeing with the 2.87 pulley if you get it. You might even consider using the 2.87 with water/methanol injection

 

Have you guys heard about the Snow Performance water/meth injection system where they optionally also will sell you a little bottle of nitromethane? You can only add a small specific quantity of the nitro methane to the water/meth reservoir for a 30 to 50 hp boost. They say that the additional fuel in the nitro methane keeps you from running lean as long as you don't exceed the quantity of nitro specified. I have never tried this, but I will second the concept that water/meth adds an intercooling effect which adds safety and a bit more power. I just don't want to tune using water/meth cause then if the system ran out of water/meth or stopped up, you might run lean. I know some of the systems have saftey features to prevent that though. My question is - if you tune for not running on water/meth and then just add the water/meth system for additional safety... will the water meth throw off your tuning to your disadvantage in any way?

 

LOL, Thanks guys. I was trying to keep it cheap. I do not have headers or cams. And of course I would want the Crawford headers. So either option, or both would lighten the wallet. Oh well, guess my wallet is about to loose some weight.
