Hey guys,

I think its time for me to step up to the plate and start upgrading my internals. I was wondering what some of the engine pros would recommend for a Vortech car that is not a daily driver. I am actually hoping that the car will have some serious lope at idle. Any ideas?

 

big *** cam.....................

 

Thaaaaanks JC.

 

IMO GTM supercharge/NA cams or JWT will be the best choice

 

I believe he wanted a big lope in his idle . The Nismo and JWT [ from what I hear ] are basicly the same and will not give you a big lope . Idle is a little choppy but not what you are looking for . I dont think the GTM cams will be much different .

What is this car going to be used for ? Stock Vortech SC ....or custom setup ?

 

If you want something loopey our GTM Stage 3 cams are what you are looking for, Same cams I will be running in my personal car

Where can info be had on these George? Good for a NA build.

Thanks

youre welcome.......i wish i could do more that waste ban width sometimes... lol

 

JWT makes over 5 different cams alone for the VQ35 that are readily available (and a few that are not advertised / "race only") , so it all depends on how agressive of a cam you can handle. We will be proyotyping yet another set of JWT cams (lets call them C9's) and they are so agressive that I am guessing that atleast a 1,300 rpm idle re-flash will be necessary for these monster cams (the most agressive cams for the VQ on the market to date)

With the lagging nature of the Vortech, as agressive of a cam as you can handle would be best, IMO.

Most companies do make more than one cam . I didn know JWT made so many though . Good to know !

And this JWT cam maybe what the OP is looking for !!!!

 

^+1 jwt does have alot to choose from then just the S series. They also have the c series which is more for racing than for the street, but require you to switch out you springs and retainers from what I understand.

 

Our GTM stage 3

Stg3 N/A, 302/292 degrees @ .012”, 256/250 degrees @ .050”, 11.50mm/11.00mm Valve lift (intake/exhaust)

The non advertised jwt cams are huge. You have to call and ask for them . Wish I knew that when I bought my cams, the revup S7 cams dont even make the idle funky at 450" lift.

 

Sounds like that would be the choice then !!

JWT cams FTW !!!!

 

I talked to jim wolf about it one day when i called them. One of the bigger cams he sells will make power all the way too 8500-9000rpms. Of course you either use it with like 15.1 compression or a turbo . He said it would work well with turbos, and i think they are the same price. I am not sure if they sell different springs than what is listed though. The next set of cams when i rob someone for money will be some big jwt cams and brian crower springs/retainers.

Does anyone know if the oilpump and waterpump would be ok too 9k rpms haha.

 

yes we use JWT cams.

PM me for all you performance needs

 

IMO i'm not so sure about running huge cams with the vortech unless if you're reving to like 7500 rpms at least. Huge cams are just going to kill your low end and a lot of the benefit for higher rpms are going to be beyond your redline

 

Do any of the cams currently on the market cause problems with piston/valve clearance?

 

When cams are done right and the right ones for the particular aplication is selected, the cams should not only deal with the higher RPM's better (making more power), but even more importantly will minimize all that lag that is inharent with the Vortech and get you up ionto boost ALOT quicker. The goal here with cams would be to make better use of your boost/power and make more of it.
