what cams would be best with the JRSC....? turbo?

 

2291012 or 2291013

2291012 will make u have more mid range power, but not so much of the top end,
better daily driving.

2291013 are more topend and more for racing.
but cat cams says you wont need to do any eninge mods to this, and you can jkeep the springs and retainers oem.

 

These sound nice, might be interested in a set

 

Here is some of the information I obtain from Cat Cams below. The rpm range is different than what other manufactures. Cat Cams tries to show what is more realistic as far as where the most power will be gained at. The 2291011 will gain most power at 1500 to 6000 rpms. The engine will still make hp up to 7,000 rpms like it does stock cams, but the power gain will be notice in those rpms they are saying.

The band in which this camshaft set should work at its best when the essential modifications to make it work are done, like adapted engine management system when required and adapted compression ratio's and induction and exhaust systems as well.

2291011: 1500-6000RPM
2291012: 2000-6500RPM, engine management system to be adapted.
2291013: 2500-7000RPM , " " " " " " , slight increase in compression ratio advised.
2291017: 3000-7500RPM, turbo application only
2291014:3500-7500RPM, min c/r 11/1, improved exhaust sytem advised as well as adapted enginemanagement system
2291015:4000-8000RPM racing or mild drag only, minimum comprssion ratio 11.5/1, engine management to be adapted
2291016:4500-8500RPM racing or drag only, minimumCR12/1, race exhaust system needed.

Note: depending set up of engine, car and gear ratios it is obviously possible to replace these powerbands mildly up or downwards, but more than 500 RPM shift will be hard to realise.

 

dyno's

before and after.

 

Would you be offering a tune to compliment the cams that are ordered? If so, how much would you be looking at for a package deal? Would you be offering the tuning with the VCT, or would the delete be required?

I know they can reduce the base cirlces of the cams to alter the lift at TDC so that you dont need to worry as much about your valves kissing your pistons. Is that another option that we could look at or is that incorporated in the price?

Cat Cams noted to use the 1st camshaft should not require tuning, but the others would. We would recommend a custom dyno tune for the best results.

I talked to Cat Cams about this. They said reducing the base circle on our engines does not change the cam profile. You still have to be concern about piston to valve clearance espcially on the higher lift camshafts they offer.

 

Thanks for the responce.

Im not a fan of email-order tunes, but there isnt anyone local that is a knowledgable focus tuner, especially when it comes to the sublte complexities of the SVTF.

Is tuning for these cams something you would be willing to provide? I know it would come at an extra cost. Would you guys be tuning with the VCT or deleting it? Last thing I would want to do again is tweak some more valves.

 

again......need actual numbers to sway me into buying a set of these....

We would like to sell a customer SCT flasher with the mail order tune required for these camshafts. I am not sure how long that might be for to be able to offer tuning. We would sell the flasher ourselves. The tuning and tuning support would actually be done by Focussport, as they deal with tuning all the time. We would need to have a customer that wants a set of these camshafts go over to Focussport. Focussport can install, tune , and dyno the car. Once that is done Focussport will know what is needed to be done in the tune, so we can than be able to offer the option for a mail order tune.

It would be recommend to keep the VCT to help to keep the low end torque.

Cat Cams can give us an idea of what a certain camshaft should gain on a given setup. If you want to tell me which camshafts you are looking at and your current setup, I can find out.

Actual dyno numbers would be available later once we get results from our customers.

Actual dyno numbers would be available until later. Once we have customers buying these with dyno results to share with us, we will be sure to post the information online.

 

We need 3 more customers to do the group buy.

yeah I agree, any dyno's for these?

 

I would love to see what Cat Cams says these cams would produce for power over stock. Hit them up and post up their responce. If its signifigant I would be more interested.

I am as far from California as I can be, so I guess I would have to wait to see what Focussport can do remotely before I say yes to a set. I have the skills to install myself.

Keep us posted!

 

We need 2 more people to do the group buy.

 

Have you heard what Cat Cams would produce for power levels over stock?

I have ask Cat Cams for hp numbers for a stock car with these camshafts, but it looks like all there customers have highly modified cars. These camshafts are better than the stock ones. I am sure it gain hp, but do not know how much at the moment. Hopefully we can get a customer with a mostly stock car that wants these camshafts. You would think it would gain alteast 15hp+, but we will have to see.

 

I'll be a test car!!!

 

Got ya. Hmmm...I'll have to think about it a little more. Thats a good price on the cams, but overall its going to be a pricey endevour. Good opportunity for someone to make a NA monster.

 

bump please
