I want to make over 500whp on race gas on less than 20psi. Trap 125+mph on slicks, and run mid to low 11s. I want to avg 27mpg. I am going to change my turbo manifold from the reliable log to a tub...
before you put that motor in the car, you may wanna change the log manifold. I know from experience, the VE motor hates overlap. The stock cams have 48* of overlap that will kill the power. So plea...
The GT4292r isn't really big. It will flow plenty of air for 750whp. But you wouldn't have to rev high to get really impressive numbers! I have seen what this turbo can do and twin scroll makes ton...
Also remember that the engine pulling a vacuum is in effect creating a pumping loss. It takes energy to create that vacuum. A diesel engine has no throttle plate and therefore no vacuum. It is very...
On my p11 I hit 97.5mph in 3rd at 7500rpm. In 4th it is 130 or so easy. I like the p11, but the b13 tranny will walk on it if you don't have enough power. I have around 400 or so and 4th is a ton o...
HC too high + CO too high = Very rich/missfire
HC too high + CO good = Missfire
HC good + CO too high = Running too rich
CO good + NOx too high = Lean or too much timing
^^^^ That is very interesting miko. I have thought about this many times and I didn't understand why people were changing springs to go to the N1 cams. The ramp angles are very very soft.
Read it in tomorrow's technician article a couple of months back about the new convertor. It is supposed to catalyze CO2 into O2, not sure what kind of effect they have gotten with them though
I built my car with several factors in mind, and mileage was one of them. Currently I avg only 20mpg because everytime I pass someone I use a full gallon ;)
^^^ correct. The only difference is the newer cat convertors have palladium and rhodium in them to help catalyze different gasses. The older cats would do HC and the newer ones do HC, CO, and NOx.

This is the same problem my friend had with his JWT too. I talked to him about it and his pp looks diff than mine. Mine had small diaphram fingers on it while his were the big ones. Could that be a...
nice man. Good to see you are making progress. At least you have the resolve to really tackle a project like this. They can be a pain to find. Maybe greg can get it cheaper for you? try some auto p...
as far as the question goes, there is only one thing that I can see causing the problem with adjustment. That is the pp design. I have seen a few brands do it and others don't ever have a problem. ...
1. the blow by gasses are gasses that are pushed past the rings on the compression stroke, so yes, they are metered before they even get into the combustion chamber. Now you will notice the hose th...
the vacuum can be checked via the evap port with a green cap on the driver's side of the engine bay. You hook a tester up there and you can apply vacuum to check for leaks. Also, if you hook up a s...
