Octane Boosters and Fuels

Ok guys, been looking at this stuff for a while now, need some input.

Synionic and NOS octane boosters are supposedly "cat safe" but there is a debate about that, they both use MMT as the primary booster, works well. The Millers CVL Turbo is very very good but not good for use with cats "for prolonged periods" so be fine in the lude but not the Stagea. Then we have road legal race fuels like VP StreetBlaze 100 and Motorsport 109 both of which are high octane and listed as cat and O2 safe with no arguments saying different.

On the Stagea I have a boost controller and fuel piggyback, more octane is good when adding boost, this is a given as det kills turbo engines really fast at times. My question would be do I use boosters now and again or just buy a drum of race gas and either run it straight or blend it with momentum99 or v-power? What are your thoughts?

Thing is when I raise the boost I'm not sure v-power will be enough, technically it's not enough for the 100ron the car is designed to use on stock boost anyway but it copes. Raising the boost will require certain conditions and running lean or knocking badly are two things I don't want, might be 280 quid a tank but race fuel would do it nicely, might just have to keep the boosters for now if I fancy a blast at 10psi. Do need to de-sludge the intercooler to restore some cooling too or get a new one thats works better lol but that might cost a lot too.

I watched an episode of 5th Gear where they tested all these 'octane boosters' and they found that none gave any kind of a power hike and almost all of them actually had a negative effect on the power output...

Get some of that Blue Thunder nitro fuel for R/C cars, pour some of that in the tank with your vPower - that does give you a boost!

If you're willing to spend that kind of money on fuel you might as well tune it to run on methanol. It costs a whole lot less even if you factor in new fuel parts every year or so due to it eating the inside of them.

Otherwise just tune to max brake torque or until you get near knock on v-power and be done with it.

I did it in my green Lude.. 200ml of Nitro fuel with £20 of Tesco Momentum99 - i'm sure it was more responsive under acceleration and in VTEC it really screamed! I don't know if it did any damage to the engine though as I flipped it a few days later (unrelated!)

Turbo cars love methanol coz of the increased cooling. Smells funky too :hurr:
