: Cams vs. JRSC

I don't know which to get so I need some opinions and good insight. The cams with the flasher are much cheaper than the JRSC and have significant gains. I think with a cai and cams the SVT is looking at 172ish + hp to the wheels. Now that is nowhere near the 200ish whp for the JRSC but I have not been impressed with the 1/4 mile times from the JRSC. Most are running very high 14's. There are a few exceptions in the mid to low 14's but the ones in that range have the 42# injectors; Coincidence? One the guys who had the prototype cams in his car stated that comparing the cammed SVT to the JRSC SVT that the cammed car seemed faster. Now n/a is great but I am wondering if just most of the JRSC users did not switch to bigger injectors if that is why they are running very high 14's? Or now that the new SCT flashers have a program for the JRSC will times improve? Ok I am rambling now and probably not making much sense, so any insight here will help me. What do you guys think?

If you are talking about future modifications then I can try to reply since no cams are out for the SVT yet.

As far as how much you would be putting down to the wheels with the CAI and Cam (when it happens), I think you will put down like 165 whp max. Stock, most SVTs put down 156 whp.

I think that any type of boost is good for the SVT. It might not be extraordinary boost but if you are not gonna go for a $3000 turbo budget, I think it's a good option.

If, and when cams are released for the SVT, it should break 180whp with a good flash.

Wow....I didn't think that much could come out of that crappy engine..:)

Now I understand why sexy2002 is saliving.

I think that tom said that the stock JRSC runs rich in the low rpms and lean in the high rpms and said that instead of the black box you should use bigger injectors, tune, and a new maf...

Well as far as what size injectors people are running I'd say most are running the stocks since the JRSC is tested with everything stock on the car. Anything else that you but on is just more power. Focus central does have a boost upgrade kit for the JRSC that gets you 15whp for pretty cheap. If your looking for a drag car you should of bought something else. If you want a drag car out of your focus get a turbo or one of the higher priced S/C like the procharger kit.

I am not looking for a drag car. My 5.0 on the bottle was a drag car; I want a 14 second quick little daily driver. Not a drag car. thank you have a nice day.

It should make 180 whp with all the bolt ons. I forgot to add that part.

Eeesh...

Injectors do not provide power EVER. I see no reason to upgrade the fuel injectors on a JRSC unless you are maxing out the injectors. If you have a JRSC, then get to a dyno, check your A/F as well as fuel pressure and you can find out whether or not the injectors are enough for 210whp. My guess is that the stock 30lb'rs t are right at the edge of being maxed but might be ok. And I can't see any cheap upgrade getting 15whp more out of the JRSC. Any extra power out of the JRSC will NOT come cheap, and tuning will be required as well as an upgraded pulley.

As for the original question, the cams with all the bolt-ons should come near 180whp with about 145-150 ft/lbs of torque. The JRSC will give you more power and for just daily driving, I say go with what fits your budget. You'll like the cams, you'll also like the JRSC. I only suggest cams to those who plan on tracking their car. But bang for the buck.. the cams are obviously alot better way to go. And remember you might see a head package at some point which will have the possibility of pushing power over the 200whp mark all naturally aspirated.

I have no real interest in FI or nitrous as I take my car out on track (and will do so more and more) and so am really looking forward to when I can get the power I want N/A. Hopefully it will all come out this winter or early spring so I will have a chance to get ready for the track / autoX...

very well put.

Anyone have a dyno plot of the cams? I would think that 180whp would mean even a bigger loss of low end. The low end on these cars sucks as it is. I couldn't tolerate driving it if it were any worse.

i imagine there is going to be more than one profile on the cams. they went through too much to get them to work on the car to only make one profile. there was a dyno on the jet a few months ago on the one that hit 180 if i remember right

might not be a bad idea to have a low end street cam for the svtf. interesteing :scratcheschin:

It never hit 180.. the original dyno plot hit 178whp but that was with a bounce off the rev limiter. The power was a steady 174wh with a 146ft/lbs of torque. It was my car.

The reason power was down was I lost about 4-5 whp with the exhaust and 1-3 horsepower with my current intake. If I would have stuck with the stock exhaust power would have been much closer to the 180 mark.

I have all the dyno's at home, but I"m not going to post them, because I get to many questions about why my power was so down. And I'm tired of explaining. Trust me 174whp (without the rev limiter bounce) and 145 ft/lbs of torque. From a baseline of 159whp (WITH the rev limiter bounce) and 139 ft/lbs. The extra torque gained was not because of the cams, but the tune from SCT.

Mods at the time were:
Apexi Exhaust, Off Road Pipe, Cool-Flo intake, Crank Pulley, Cam Gear (not tuned on any of these runs)... that's about it.

so why was power down in the low end, belacryf [:D]

Cars are like women, his car wasn't feeling good at the time!

An N/A motor would be something to brag about, but I think it would get worse mileage than a F/I motor. Mileage for F/I should stay the same if you keep your foot out of it (daily driving). If you have a high hp cam in it I would think your mileage would suffer regardless of driving habits.
