So I'm looking to get some more power out of my 1.7 FI motor and thought NOS was the best bang for the buck. Of course I would love a 3.2 but that isn't in the budget. So has anyone here ever used nitrous on a stock type 4 motor and had success. The idea was to only use it during autcross events and the like. Any advice would be helpful.

if keep at reasonable levels, it can be used...the real question is whether or not the organization you plan on auto-x'n allows it.
not allowed in PCA and I'm betting the same for SCCA |

there was a guy that ran nos... 50 shot I believe on a stock setup...
He also ran his exhaust straight off the heat exchangers (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) It was.... loud... Didnt talk to him about if it was quick or not... but I would think a turbo would be a better bet. You'd run through nos really fast on an autox, and it would danger the engine.. |

ive heard use 2 tanks
1 to blow throught however you are gonna deliver it (dirrect port, wet or dry, wet would be best on a 914 and remain resonable) 2nd tank to blow through an intercooler you would have to mount in the engine that would blow super cold air throught there to help cool it you probably wouldnt wanna mount a button in your stearing wheel or nething tacky like that you could make a bracket and mount it off the rear bulkhead with a switch that would open the valve only when the throttle body moves to full open or damn close i was thinking about doingit but decided against it my main worry was giving it full throttle out of the gate in 1st seeing as how 1st spins out so fast it seems like it would be easy to over rev it and pop the engine |

Yeah, the idea was to have it come on only at full throttle, no fancy buttons for this application.

The thing to do would be a full throttle switch at either the throttle body, or the gas pedal, and a switch to turn it off... You dont want a wet setup spraying extra gas in the system when your out of nos.
Intercooler would only help if the ambient temp was lower than the intake temp... since his application is N/A, the ambient temp is the same as the intake temp (give or take a couple of degree's for engine temp radiation) |

Hey Jim, I did a search and saw you had a thread on getting more power out of the 1.7. Did you try anything yet?

Sup neighbor!
If you need local help with your car (between tests) I'm local, have had a 1.7, 2.0, and now a 2.7/6. (IMG:http://www.914world.com/bbs2/html/emoticons/wavey.gif) |

http://www.aircooledtechnology.com/store/h...ome.php?cat=308 here's the massive type 4 engines by Jake Raby. I like the idea of the 2.0 turbo. It's price ballpark as a six conversion byt weighs less.

And that combination is getting a comprehensively developed Turbo plumbing system as we speak... EFI and intercooling is standard on every arrangement I am working with.

Sounds like an incredible combination, what kind of HP figures does it have w/ the lightened flywheel and balanced internals?

Hey Dr. Evil, have you made it out to the CPA PCA autocrosses at the Giant Center this year? If so, I'm the young kid in the really low and really bright orange 914, the name's Sean
