Thread: N1 + 9k + Big boost & HP.. Crank work?

Are you guys with high powered VET Builds with big cams (20v or n1) and running 9k+ RPM doing anything to you cranks other than the basic balancing?

I am building a high powered VET and will be using N1 cams. Just thinking about crank work. I was planning on using my W10 DET Crank

I would say go for it. There is a very reputable member here by the name of Coheed. He is makeing very high numbers with a simular set up and a 8 weight crank.

You dont need an 8 counter weight crank but i would opt for a ati fluid damper for sure.

i used a stock de 8cw crank, just had it cleaned and micropolished the journals. if you want to go any higher than 9500 rpm i suggest an ati damper as it can cause damage to the oil pump.

I was fine with a stock pulley to 9800 but went to 10,200 and had problems with it damaging the oil pump gear teeth.

N1 cams, bws400sx 67mm, 29lbs of boost. 723whp.

When we first ran our old S15 drag car, it used a OEM DE crank in it, rev'd to 11K or more. Oh yea it also had N1 cams in it also when we first started. N1 cams may not be your best option though.

What opinions do you have on using n1's? theres a few members here who have had good results with n1's and big turbos.

We honestly didnt like them. The powerband wasnt what we were looking for. It seemed to choke above 7900 or so. But that also could be due to the fact of the turbo size (GT4718R). Smaller frame turbos are ok with those cams, but still remember those cams have profile for all motor applications.

What would you recommend. I will be using a GT3582R 1.06 exhaust or the GTX3582R. I have all the OEM cams. I could sell them and get kelfords but i would like to hold off on them for now due to the price.

If you dont want Kelfords, then any one of those are good options. Stock VE, N1, or 20V

Any comparisons from the Kelfords to N1's

I was thinking about the 184-T's but seeing how the power on my car just kept going without even a sign of going down at all I just dont see a problem with them. This was on a 2.0L motor also so take that into account.

Im going to be having some extensive portwork and big valves done on my head, so it will be interesting to see the gains just from that. I still might consider the Kelfords down the road but just cant justify it right now.
