N/A build in the works
 
Ok first off if all you got to say is for the price you should go forced induction keep scrolling please true or not it's not what I'm going for. So I've been searching for good answers in the efforts others have made in doing this and theres not much info out there I've seen sadly. I've ordered Jwt c2 cams and the Brian Crower stroker kit with 13.1 pistons bored 20 over. Upgraded oil pump from sucker punch and Cjms baffled oil pan with many other replacement and small upgrades on top of just about anything else most go for "fbo" with flex fuel that's already on the car.
Now to what the post is for.... looking to raise the rev limit and wondering who all has tried and what are the remaining weak points in doing so. floating valves? Lifter issues? With no good options really for replacing intake cams or valves or springs due to vvel is that the next issue/weak point? Or am I missing something completely? Would love to hear from you guys that have some experience with building a vhr and those pushing it on the track cause that's what she's being built for and where she spent alot of the last 3 years besides up on a lift lol. Thx

With VVEL you are stuck at 8000rpm. That is actually my rev limit. The only other thing you can do is go to a standalone and swap the heads out for VQ35VHR heads or the like.

Get rid of the BC striker kit and go with a Bryant racing billet crank

Looks like he already ordered it.

I've been researching for almost 2 years and havent heard of this and like I said I've done ordered what I've listed. This is why we need to share this info I'd like to know what's available for this car

Not sure which BC crank you got. Expect to spend more at the Machine shop, it will need some finish work.

So many questions to ask? Who or what made you go with a BC stroker kit, and the piston combo? Like spooler said you"re going to have to spend more money on that kit to get the proper tolerances spec'd out for everything to work in harmony. PICK YOUR SHOP WISELY!!!.

- Far as raising you rev limiter up is pointless if you're looking to gain more power, only one person I've seen as made power past 8K he ran Jun cams, a dry sump and at the time bunch of 1 off parts. There is one person, Rabbit Hole Motorsports who is building a high rev VVel with upgraded goodies on the intake side. So he will be his own guinea to see if that solves the valve float and unwanted harmonics with revving and sustaining 8,000+ rpms. I would of talked to either Mamotorsports and JWT (I"m sure you have heard of Valkyrie's 370z) about your build before pulling that trigger. They probably would have pointed you in the direction of at least a bryant racing billet crankshaft probably one of the best custom crankshaft made. I was going down this route 5 years ago, but wanted more power. Also you probably could of had a custom ground exhaust cam specifically made for your motor and needs.

Info you're looking for is out there, you just have to be annoying about getting that info. If you're going this far into building the motor you really might want to consider a standalone of some type, Vit tuned makes a Pnp for a motec 150, Mamotorsports has both motec and emtron kv12 tuners, don't know much about dynosty haltech 2500.

If you're stricly using it for the track and only running race gas bump the compression even higher, with a great tuner and a standalone you could still run pump gas with octane booster without it blowing up. Kels made 600HP (500whp+) on pump with octane booster.

Pm BGTV8 He is building a VVel ITB DWB. He will answer any questions you have to a far better degree than i can. Hope this helps, good luck on your adventure.

I apologize for not going into much detail, but with these type of threads about build the case is like the old saying "You can lead a horse to water, but you can't make him drink" Plus its late dam it

Sasha at One Point Racing has a ton of info. He holds the N/A HP record at 600+hp. Took him years and a tri-axle load of money.

Leadfooted. How are you planning on using the car. DD with some track, or track with a little street?

Track with some street driving for fun and meets till next year when the cage and interior strip happens hopefully. I'm not looking for any records I'm not tryn to dive that deep in.

Thanks for the info. I would of thought that most of the issues would of been worked out with it being a kit. Yeah it's all going to machine shop to be looked at prepped machine work done and block to be assembled. I talked to friend that builds motors about some of this stuff and we came up with what I've put together. From what I gathered with the shops i talked to if they're not getting to build it they dont really care to help with info. I should of came here and made a post for info. But looking thru a lot of the posts I've found it just gets the same spend tons of money custom one of pieces or go fi.

Yup, why would they give away there business secrets. Great machine shops are backed up beyond belief. My motor is on a 6-11 month waiting list.

Those guys are fantastic though. When everyone else is blowing up and you are still running. Worth every bit of waiting you do.
