thanks for the help. i have a friend's racegas map and was simply curious as to the general differential racegas and pump/alcohol w re to timing. i do not plan to run racegas but am interested as to whether he is running more timing than i am. i am aware as to how to reach optimum timing...

"Race gas requires high timing to burn properly..alky usually works better on lower timing.. " from a 03 Razor post... my question: given 25 psi boost... what would be optimum timing advance for 116 and what would be opt timing for pump 93 and alky? i am most interested in the...

i have a year on my NX Y fitting. it is currently in like new condition. i will keep an eye on it and consider it a maintainence item if necessary.

FYI: my calibration is: 500C = 932F = 5.107 AD595V/2 = 2.554 900C = 1652F = 9.233 AD595V/2 = 4.617 hc

Brian, your conversion table very closely resembles the Analog Devices table for their AD595 chip... which i run. here's the link: http://www.analog.com/UploadedFiles/Data_Sheets/421725987AD594_5_c.pdf the chip outputs 0-10 and you add a divide by 2 circuit and read 0-5. all that...

Thanks Julio! while i am not totally tuned out my 2.6 liter, that'd be 158 cubic inches, rotary is making over 500 rwhp on two M10s. no knock and 1100 F pre turbo egts! generally rotories make around 2-300 degrees more egt than piston engines.... there's probably a bit of tuning to do as...

perhaps this has been addressed and i will do a search but would like to hear some comment: since our systems (mine is Alkycontrol) are generally manifold pressure actuated it would seem that between shifts and into the beginning of the next gear they could run lean while the system catches...

i searched and read a number of threads on the subject but do still have a question. i run Razor's setup. nice BTW. i have a 4 gallon Jaz fuel cell w anti slosh foam. i don't want the foam exposed to meth any longer than necessary so i will drain the cell. how about a gallon of...

perhaps if you could be more specific as to "explode" you might get a helpful answer. is it the turbine housing splitting from too much heat and pressure? if so you have way too small a hotside. (i know). what specifically is your turbo besides ceramic? details details solves your...

slinger, wisconsin $1.99 gallon Wolf Petroleum. downtownish Slinger. sorry but don't have the address/phone immediately available. i believe the price is for more than 5 gallons. i recently bought 10 gallons at that price. i think you will need a container as you my not be able to place...

when i received my Alkycontrol kit i scratched my head over the sealed plastic bag containing the pump... in it were droplets of alcohol? water? tequila? oops we are back to alcohol... so i happened to be talking to Julio and i asked him and he said very casually, "oh, that's just a...

i am really happy to be able to give something back to this site as i consider it the most valuable source of auxiliary injection info on the net. i have benefitted greatly from reading the entire site. the chart came from Techedge's website. Techedge made my AFR setup. thanks Techedge and...

FWIW, as the altitude rises from sea level the amount of oxygen molecules per volume decreases on a non-linear progressive basis. oxygen per volume determines everything in that if we have less oxygen we have less power etc. tuning regiman should not be effected. you tune for knock...

Julio, thnx for the link to Newark. i purchased 2 Honeywell pressure sensors a few years ago and they really came in handy. i log exhaust backpressure so as to zero in on hotside turbine and housing sizing and fuel pressure. Honeywell has since dropped the 4000PC series of pressure sensors and...
