im putting together a 400+whp d16 as you may know because of all the "stupid" questions ive had lately.

should i use 93 octane pump gas or race gas for my 400+whp d16?

i can get TrackTek 110 octane leaded fuel at the pump here.

well id say pump if you plan on dd it. Or it might throw your tune off. Plus your not always going to run it. unless its just a race car, id say pump gas...get sunoco 94oct, thats what imma tune on, and what i run

its not a daily driver and its not a "race" track car. it will be driven maybe one day a week and it will have 400+whp all the time.

thats what i was planning on but i like to have other peoples opinions on everything.

but damn that **** is expenisve, haha

leaded gas wont hurt anything will it?

But like I said before, if you don't wanna run racegas all the time, look into a simple water/methanol injection system, it will allow you to run high boost on pump **** and since it's not a DD then just check the water/meth resevoir

leaded gas burns out ur O2 sensors really fast prolly after you tuned it you would need another one.

mike93boost

ok so dont run race gas? nad you think pump gas 93 octane will be fine for a 400+whp d16?

Pullig

id think you would have to run race gas to attain 400 whp on a D. Since im sure it takes over 20 psi to get that. But i really dont have experience with it so its really just hear say.

yea it will be over 20psi..

so i have to run race gas and change my o2 sensor every week?? what about my wideband sensor? damn this whole 400whp d series is really starting to suck.

adseguy

and you need to run a new wastegate valve for constant race gas use.

Boost doesn't determine race gas use and neither does HP(kind of...bare with me). Torque is what you look at. Many stop at around 300wtrq more or less.

well i will have less 300wtrq i believe...

what do you mean a new wastegate valve?

Pullig

well just tune it on the race gas with ur wideband then whenever you run the race gas again just dont run any o2 sensors i mean that would save u from buyin new sensors all the time . your tune shouldnt change any unless ur changing altitudes

97turboteg

you can run pump, but its going to be harder to get to 400whp, and more boost....but its definately exceedable. Dont think you cant reach your goal on pump. theres a thread on here about guys getting like 600whp. And your o2 sensors wont need changed that much, once you get it tuned and running at the right air fuel it will be fine for a while... good luck man

oscarmayer

if your engine was nort build with running leaded fuel then YES it will damage the valves and their seats, the wastegate must also be designed to handle leaded fuel too. There may be otehrs parts that need to be specifically modified or repalced to run leaded. my engine was totally build with being able to run race fuel when desired, so i have no issues running both.

mike93boost

well what parts were specifically built to handle leaded fuel.. im spending quite a bit of money on having my engine FULLY built.

purpleh22

I believe that internal parts would be safe (valves, seats, rings etc.) running leaded race gas. Lead actually functions as a lubricant in an engine. There can be some wear problems if you run an 'older' engine that was intended to run on leaded gas, on unleaded. Current valves and seats are typically made of harder material and work fine with either.

mike93boost

so i still need to decide on whether to use race gas or not..

platinum00

i think your going to have problems making a reliable 400whp on pump gas and a D series, but it can diffently be done.

do the wideband sensor burn out as easy as the narrowbands when using leaded race gas?

platinum.

well they arent making race gas seem very reliable either..

ILLICON5000

if you had to ask that question you probobly won't ever make 400whp, at least in the near future.

obviously 400 is easier to obtain on race gas than on pump. and i'd suggest c16. and yes it's leaded. and yes it cuts down on the life of a wideband O2 sensor.

here's what you do. you get a 10 or 12 psi tune for on the street, 93 octane. and you get a full boost tune of 25 or whatever on 116. just switch the maps when you switch gas and boost levels.

yes it will be very well capable of making well over 400whp. and yes the engine is in the works and almost all parts have been ordered. car is on jackstands awaiting engine and all parts.

im not going to have two different boost levels.. it will be making the same 400whp full time.. it will hardly be driven so why not?

i have no idea where do get c16, whats the difference between it and tracktek 110?

i just want this thing to be reliable, last a long time, and not a lot of headaches.

purpleh22

The difference is 6 octane points and a little more insurance against detonation. You can get by with 110, make sure your tuner knows what they are doing. Electronic boost control with multiple boost settings give you a lot more flexibility and units like the Blitz sbc also make it possible to increase boost as speed (gears) increase. Helpful for traction control. I use 10 lbs. for daily driving (300 whp and can increase it while I'm driving, if I want to)

SoEvoL

i use VP race fuels, they do the 100, 110, 116 ect ect. lookin your phone book for a fuel dealer in your area, or check ur local auto stores. i know NAPA around here carries race fuel, and baxter automotive parts.

dude it's not going to make 400whp if you don't know where to get c16 or to find out where c16 is sold. and even if you do make it, it won't be reliable, and it won't last a long time, and it will not be headache free.
