I need to start a poll i got 4 days to make up my mind. Should i go turbo and use the bottle as back up or should i go all motor and bring on the smurf bottle. It's been a long time coming and now the time has come

what motor are you using? and what are you doing for fuel/intake? also you wont need to run that big of a shot on a turbo motor.. Nitrous is very efficient on a turbo motor.. i have seen turbo motors with nitrous net 100 to 150 hp with a 50 shot on dynos... i am a fan of nitrous tho i will post some pics of my set up if you would like

cheers PaTricK

Big streetport and turbo, you can make all the power you will ever need and it's far more reliable and much more streetable. I'd lose the Nos...

I'm with the guy above me. Large streetport and turbo. I just picked up my turbo yesterday, and I'm only going with a mild streetport. Hopefully by the time this thing is on the road I'll have internet again and will be able to see the videos of it.

also like others have said.. a large street port + race exhaust port is alot better for turbo... if you want to do turbo and Nitorus i say only do a 50-75 shot the gain you get from it will be very noticed my 2cents
