gas throttle bodies whats the difference tried doing a search but its farked or something, if anyone could refer me to a site that would be good thanks

i believe there is no difference. gas setups use a gas/air mixer pre throttle

i just read this gas research website and it is talking bout a trottle body that has 3 stage adjustments to alter fuel mixture etc quiet interesting

it narrows just before the throttle body, i took this off my old vl as it came with factory gas. i can take a photo if u like i got it lying around somewhere. as soon as i took it off i noticed a slight power increase its significantley smaller than the std throttle body. the factory ones are i dunno about others its like an adapter thing that fits inbetween the snorkel and one of thos rubber stretchy things(no clue wat there called) that attachs to the throttle body dont know if this is what u wanted to know but this is all i know of it Some original photos have not been recovered yet.

this throttle is a gas research product, it looks very similar to "gas-747"'s throttle body, its very interesting stuff, they seem to hide no secrets on tuning and problems very helpful site it all got me fired up today when we filled forklift tanks 130 ltrs for 50 bucks i worked it out to be a saving of about $2500 a yr if u fill up a tank a week

wow faaaak ok i have no idea wat im talking about lol ive only seen the factory gas ones and theyd have the opposite effect ud want but yeh above is wat my factory looked like anywhos mind if i grab the site u got the info off mate? very interested myself

i thought they use a coverter not a throttle body...

lol, the convertor converts the liquid to a gas and the throttle body mixes that gas with the air for combustion, so yeah, you need both! I've only ever used the Gas Research gear and swear by it... although it is expensive, it does work well and looks tough too.

on the topic of gas dont wanna hijack but dont wanna start a new thread, is there a difference in straight gas and gas research? if so are they performance differences?

straight gas means only using LPG as the fuel. Gas research is a company that makes many products to run your car this way. A '3 stage' tunable setup means it has a metering rod in the throttle body with 3 levels so that more or less gas is let in at each stage of throttle progression

Gas Research hardware is only for a straight gas setup, therefore you can remove all the pollution crap from your post 1972 vehicle.

ahhh so i thought so. say u had fairly stock vlt exhaust,t04,fmic and wanted to run it on gas. does straight gas only make a difference with higher power applications or will it give equal or higher power? id love a vlt on gas just something different i dont mind forking out that extra $3000 or so for it but dont want it to be an animal like gas-747.

straight LPG will handle higher compression ratios than petrol. If you're going to do a straight LPG motor then best build it for that purpose!

whats the laws with drag racing and gas setups? anyone know?

but you can get your big power figures from the right setup, just because it's LPG doesn't mean it won't perform, like I said, gas loves higher compression, and with forced induction, it's even better!

Wow what interesting views people have on lpg. Whether you believe me or not is another story but ill set everyone straight on a few things. Firstly gas research is not only for straight gas. You can have a duel fuel gas research setup on your vehicle. The way they market their product is that they can tune the mixtures properley with their setup. Secondly for N/A engines they try to brake even on power on lpg in relation to what you had on petrol. Thirdly Turbos don't like high compression it means less boost. All the hot lpg turbo cars run 7.0:1 or 7.5:1. Which is low comp.

Yeah and thats most likely your limit and id doubt youll run that all day everyday like gas 747 as 250rwkw is good enough for a hi 10 sec pass. How come I have never heard of you and I know you aint run a 10
