I tried to learn CAD once and it didn't go so well. I keep being told that Sketch-up is decent and I should give it a try but computers aren't really my thing. I was looking at adding it to a relatively small power diesel and I wasn't that worried about intake restriction. Look at the secondary venturi in a big carb. Something like that within a straight section of tubing would likely do the job. Or even a slightly flared section of tubing if you were worried about flow. Or find an old side-draft carb then wire it open, plug everything but the main-jet, remove the needle and pressure feed the float bowl (floats removed). Only problem might be finding one large enough to not be a restriction since most of those applications were ITB. Of course if you are willing to pressurize the tank then you really don't need much for a pump. Even a washer pump will do. It's not like this is a high-boost application. -Grant |

Sketch up is alright, but its super basic to the point that a more flexible tool is actually easier to use. I'd recommend you try out autodesk inventor. I had been using solidworks at work for a couple years when we switched over, and I find it a lot easier to make multipart assemblies (and do cool things with them) in inventor than in solidworks. Solidworks still has better tools for building individual parts though IMHO. I believe autodesk has a free version aimed at DIY types. |

Here's an article about pump-less meth kit.

Also, I'm in CO Springs.... SO about 6200ft. This car is SLOW at this altitude. Especially off the line. The AT really wasn't bad in Tucson, I could still get sideways from a stop making a right turn or whatever, spun up to only 3k rpm. Now? almost impossible on pavement without have balls much bigger than mine, and using momentum. Just drove to Salt lake, and even there, HUGE difference in low end power. This freaking intake manifold man... SUBARU!!! FIX IT. anyhow. Would the part throttle, ug, forgot what you guys called it, My brain is overload with awesomeness, been reading for a few hours now. But the pulsing to maintain Atm., would that be able to negate the effects of altitude? could it be adjusted a bit higher to see that it does? @fenton , @Robftss And lastly, Since flooring below 3000 rpm can't be done on stock tune... does this completely screw me having an auto essentially? Haha. The torque possible at 2200rpm (about where the auto stall is) is immensely intriguing!! I wouldn't have to wait 5 seconds to go anywhere.... I can keep up with other N/A cars in this area (further supporting how shitty altitude is -.- Took a 4.6 Mustang to about 105 from 50) but really off the line, I can floor it, and other "normal" cars just walk away, that aren't even racing... No joke, I seriously was thinking of electric power after being beat to about 35 by an Effin PRIUS. HELP ME. Thanks a ton for the new product and choice! |

I'm intrigued to see how this will work on a auto. It should be pretty seem less. Want to go faster, go wot and you get a quick gear change and your off. If you want to roll around like a diesel car would you need to lock in gear and just go wot everywhere, you would have a nice surge of torque non stop and is actually surprisingly smooth. Keep in mind with that much torque you will be breaking the speed limit very quickly even if leaving the revs low. Sent from my HTC One using Tapatalk 4 |

I wouldn't worry about charge temp at 4.7 psi on a centrifugal compressor.
The meth will allow more timing though so you will make power there.

The 400 cc/min flow rate I am using on the twin screw is allowing for 3-4 more degrees of timing advance. The problem with this simple inexpensive system is that I must keep it off until boost is at 4-5 psi which translates to about 3.5k rpms WOT. If it comes on sooner the engine loses power and "bogs" untill the airflow gets high enough. I assume the spark is being quenched by the water concentration. Since this ESC makes 4.7 psi instantly I see you having the same problem with a boost switch or a WOT switch. You can spend 200 more $ on a MAF based progressive controller if it turns out you are quenching the spark in the lower rpms.
