20+ PSI on 4th gear
This is a 3rd and 4th gear pull where the starting rpm is very low on 3rd and the boost climbs to 19 PSI. Directly when 4th gear is engaged the boost jumps to 20+ PSI. 4th gear is engaged far to early but the purpose is just to show how the Procede builds and hold boost quite well.
The fuel gauge is used as a boost gauge, where full tank represents 20 PSI (half tank is 10 PSI etc.). Select HD video and turn up the volume |

Im running 18-20 lbs with a AMS intercooler, muffler delete, and DCIs, so you should be good if im good on stock turbos

lower it before you blow anything! you need more support parts to help turbos

Here the thing I want to run boost like the upgraded turbos but IMO 20 psi is a bit extreme, yet I dont have the money to get the upgrade just yet, so in doing without upgraded turbos I opted to use nitrous and boost 13-14 psi while on the bottle making the same power if not more than an upgraded turbo, but with lower boost psi which IMO will be safe!

But thats not going to stop anyone from having fun. High boost with cooling tuned safely.... vs Nitrous with its excessive torque bump and extreme EGT's tuned safely? I'm not ragging on nitrous, I had it in my last car, believe me I love it, but lets not kid ourselves and say its safer cause it uses less boost. Its still gobs of power and power kills engines (keep all things the same). 500WHP+ is still 500WHP to the engine (And yes I know there are differences internally and how each method effects what, but generally speaking). Edit - I already know people are going to pick the bajesus out of this post... lets see whos bored here LOL Last edited by Jeff@TopGearSolutions; 09-23-2010 at 09:21 PM.. |

What are you using to read your boost? If you are using your fuel gauge, although its a cool idea and works great, i wouldnt trust it to really measure boost. Get a real gauge on there.

Ive read the fuel (boost gauge) vs a real gauge mounted in the manifold. The only difference is the real gauge was read in the manifold psi, and the fuel one uses the TMAP. Under Full boost, they are both on par. Its when you have partial boost (under 5 PSI) they have different readings; this happens because the TMap is pre-throttle body and when the throttle blade isnt fully open there is turbulence in that area showing a false increase in pressure. 3-4 PSI on the fuel boost gauge is usually 0 vacuum in the manifold. |

The only load the engine is seeing is cylinder pressure and temperatures. It is (almost) no difference if 500 whp is made from the turbos or N20 (except for the poor turbo units). It is never safe to be within the first users that start to use a higher power level than the majority, and N20 is never safe on these levels where it adds 100 hp on top of an engine that already is used on a high level of tune.
The plan here is to use N20 at trackday events only and never for DD. Based on what I've seen in the past the outcome is that more engines start to fall apart when more N2O users enters the scene. The Procede will make it much safer than it would be to use a simple system, but the risks are always there with the high power levels that are created by N2O. So unless there is not a solid budget for failed engines it is wise to be conservative both on the power level and the use of N20. |
