Turbocharged vs supercharged
 

Ok I know someone probably has this title. But I’m wanting to know what is better for my automatic 13 frs a turbo or a supercharger I’ve looked around and can’t find a comparison for an automatic everything is on a manual. Any help would be appreciated thank you

A different car.

JRSC rep

read these three pages over and over. you will understand why supercharging is more cost effective than turboing

Goal?
Budget?
Car use?
Mechanical skill level?

Missed one.

My 14 FR-S is automatic and I have JRSC installed for over 3 years and 35K miles.
There are reviews below. Whatever your goal is, track or daily drive, this the best option I could see for reliability and power. Stay with the stock engine, buy JR tune, don't add any more power than the kit offers, just add an oil cooler (JRSC has options for that). You are all set.

Low psi turbo for a daily.
JRSC only for low budget track build.
Turbo for high budget track build.

Auto has long gears pairing well with turbos
Turbo much more efficient less parasitic loss. More power for less Boost and More whp per crank hp so less stress at same power level. Can setup boost controllers/wastegates to do boost by gear boost by rpm etc... for even greater control and safety.

Catch can, Oil cooler and trans cooler recommended, SSP valve body good upgrade too.

100% turbo. Less complicated, easier maintenance, much more pliable for a goal of low or high power.

Get -all- of your supporting mods before buying a kit. It's easy to be complacent once the car runs and drives and you're thinking "hey... actually it runs good, I don't need 'catch cans' and an 'oil coolers' what knobs"

JRSC is the most efficient solution. I hear this parasitic loss bs all the time. But I get 30 mpg with normal driving which is as good as the stock engine. JRSC is also the simplest solution for FI, there is not any room for argument there. Turbo is the most complicated FI solution. It requires proper thermal management which is so much harder than JRSC. And, unlike JRSC, header is replaced with turbo.

The only advantage you can get with turbo is the higher torque at low rpm which can lead to reliability problems in the long term for your engine.

JRSC isn’t bad by any means. definitely been overly hyped and marketed by certain vendors on here though.

People trying to flip one of it’s biggest flaws “no torque” as a strength. You can always turn down low/mid range but JRSC can’t turn it up. And low/mid range torque is what gives you that fun hit and added power for daily driving. JRSC is basically stock below 5k then it comes to life.

Parasitic loss is about needing to make 300 crank hp to make 240whp. VS a turbo making 300 crank at 260whp or only needing 280 crank (less stress) to make the same 240whp. That is parasitic loss. Not MPG which would be impacted but who cares about a few MPG difference.

Turbo for a daily doesn’t require much heat management. For the track then 100% which is why turbo track builds are for ballers. JRSC is the best low budget FI track build.

For a pure daily a turbo is better, even more so with autos because of the gearing.

Superchargers in general are simpler than turbos. But if he either A. has tons of mechanical skill or B. is paying someone it doesn’t matter. For a entry level wrencher Supercharger is easier. Main reason i chose supercharger. But having the knowledge and skill i have now i would have turboed.

So again. Before anything can be decided OP needs to answer the below as JRSC is far from a best in any/all scenarios.

Goal?
Budget?
Car use?
Mechanical skill level?

Yup, exactly. Barely noticeable below 5k, especially compared to any other FI solution.

The holidays wouldn't be the same without one of these threads popping up:D

Get out! You were caught talking nonsense.

You sound personally offended someone disagrees with your FI decision.

Below 5k it pretty much looks like every other FBO tune dyno. Nothing special. One of the worst looking plots below 5k out of any FI solution. Saying “stock” was a bit hyperbolic which I think any rational person reading should have picked up on. The point still stands though.

Like I stated JRSC isn’t a bad solution. And is the answer for SOME in SOME situations.

You basically stated it is ALWAYS the answer in ALL situations, which it is far from being.

Turbos have a TON of benefits over supercharging especially compared to JRSC.

But until OP answers the main questions asked of him. The answer cant be given.

Or any month of the year. This forum could be consolidated down to like 20 threads if all the duplicates where removed/consolidated.

JRSC has championships - it is proven on track.

For daily driving, I gave my 3-year experience and provided two other reviews and the dyno chart in addition. There are other experiences posted by others here. And also links to the other thread where CSG Mike states supercharger is the better (cost effective) option, his turbo build is expensive and was done to prove the point that it can be done at a much higher cost.

What did you provide? You don't even have turbo on your car. Why would I take your word for anything?

Tracking already agreed with, great for budget build. .

Personal experience is anecdotal. And forum is filled with thousands of personal FI stories/experiences besides yours or my own. Which was 100% reliable and had no issues and would have smoked any JRSC at 300whp or less, JRSC has higher ceiling to go over 300whp if desired though, couldn’t imagine having less mid/low end torque.

Dyno charts are all over the internet with a 2second google search. Copy and pasting 1 is hardly providing anything.

I already spoke about vendors pushing product, and his turbo is for the track. Which i stated is expensive. Track and daily are two completely different things.

OP never stated his goals, budget, or use.

Turbos are more efficient. They make more power with less boost. And more Wheel power with less crank power. Turbos are way more customizable/tunable can have different boost maps for octanes or usages, boost by gear, boost by rpm, can typically switch out to different turbos later for upgrades if desired. So many possibilities and variations to suit one’s needs.

But yes as i stated for tracking it is expensive. For a daily it is not. A low psi turbo, catch cans, and oil cooler. Trans cooler for autos and clutches for manuals. And you should be goos to go. Heat management is much less of an issue on a daily.

Go read all the overheating issues from people tracking in the JRSC forums and centrifugal failures popping up recently. Every system has issues and flaws. Still not arguing it’s a bad system by any means either. Just not the one size fits all, best solution no matter what in all cases like you are claiming.

So, if I could summarize...

The best option is a turbo, unless for you it's a supercharger, but also keeping it stock with headers and a tune isn't a bad option either. :thumbup:

Lol good summary.

OP never provided enough information to answer.

Which one is better, turbo or SC?



Yes.

We just had someone necro a Manual vs Auto thread. I wonder what's next.......

FTFY
:cheers:

Frickin laser beams. ;)

Let's just rip off the bandage-

What is the best ride height?
What exhaust sounds best?
Should I get winter tires?
Are roof wraps a good idea?
? Strange buzzing in dash
? Car ticking loudly
Car leaks oil....

Calm down, satan.

Forgot "What oil brand/weight to use?"

The trick is to post multiple questions with incomplete info then never return to the thread as it tops post #1001 of comprehensive info for every possible scenario.

Or ask questions that have been answered infinite times before and then get butthurt when the answer isn't what you wanted to hear.

Using search engines is one of those things like turn signals. No matter what you do, some people refuse to use them.

how much horsepower will a light weight pulley add? 10 or 20?
If I combine it with a lightweight carbon driveshaft will I beat my neighbors mustang gt in the 1/4 mile? I heard those are good for at least 30 hp.

You forgot which oil brand and weight is best. EDIT. I forgot to read the rest of the thread. Glad I am contributing so well today.

Which CAI/SRI should I get? Those add like 15-20 HP right?

Only with a throttle body spacer

Nitrous is the only way...

You guys are way off topic.

Precision vs Garrett?

I have a turbo tuned to a supercharger powerband.

I stopped shredding transmissions after I did that.

Just saying.

So your turbo has much more “tuning customization options” compared to a supercharger?
Can be turned to “kill mode” if and when you wanted, or daily, or track, or any number of maps for various octanes and circumstances?
And is probably making a decent amount less hp at the crank for the same amount of whp?

Also OP has an auto not manual. So not really relevant especially since auto is known to handle a solid 20+ ft lbs more with ease. And probably substantially more then that with trans cooler and ssp valve body.
