This is 3" dp with exhaust disconnected. You can have a 4" exhaust for more flow but there is more to it than that. every bend in the pipe is going to change exhaust gas direction, which takes ener...
I have looked at my pulley and the marks seem to be spot on. I am afraid to advance the timing more for fear of detonation and not being able to hear it. I think my pulley may be unaffected by this...
Go as big as you can. The only reason to go with a mid-sized exhaust is to take advantage of pulse tuning for NA cars. Since the turbo absorbs the pulse, it is useless. Go as big as possible. Here ...
^^^ true. The 5 is good for stop and go. I would use 6 for mixed driving. You basically want to use the coldest plug you can get away with, without fouling.
Engine vacuum takes energy, just remember this. Only a portion of a diesel engine's efficiency is derived from fuel and high compression. A diesel engine also has no throttle plate and therefore, n...
I am guessing the timing made the biggest difference. But the iridiums are gapped @ .032 and they still don't cut out at 24psi. I was amazed. Usually I have to run .028 or it will misfire under boo...
^^^ correct. The dynojet reads hp by how fast you accelerate the roller. Lightweight wheels increase acceleration, same as a lightweight flywheel. This should be able to be seen on the dyno. We wil...
That is crazy. I just put in a set of bkr7eix today. While gapping them i broke the tip off the center electrode on one. Which is weird because my gap tool doesn't even touch the center piece.
The alt on the sentra is a tri Y design and does well at low rpm, but I am guessing that you will need to change the pulley like Dre did just to have enough power output at idle. It simply cannot s...
Now that I think about it, this pull was in 4th gear. I know the clutch was slipping, I really wanted to do 3rd gear but everyone there made around 15whp more by dynoing in 4th over 3rd. The superc...
This was pump with a couple gallons of 100 mixed in. I ran 24psi, but this time it was humid out and I think my spark plugs are dying. The gap keeps closing to around .020 after only a few hundred ...
I have decided on a twin scroll T3 setup from Protech if the price is right. I am looking for a really good piece and I may even make it myself. So I am going to keep the gt3076r and make it twin s...
The iridium advantage: Resists wear better than PL, extrusion techniques make for a much finer and more reliable center electrode, Smaller electrode = less ionization to make a spark,
engine blowby is metered. At some point the air that becomes blow by was metered before entering the engine. It is not, however, metered again set up the oem way.
I still have a 4" pipe I made for my recirc system. It works great. I used it but I found that it was hard to mount the lightning maf far enough away from the turbo. It was experiencing some turbul...
I bet you will nail your goal. Your car is just insane from the videos I have seen. If you are making anywhere around 320whp on 20psi (you are) then you should do 11.1 no problem.
