I CANT MAKE A DECISION!!! Jrsc or edelbrock.
I know, there are a million threads on the subject. I have spent countless hours researching, watching videos, talking to people, etc. But I just cannot decide on Edelbrock or Jackson racing supercharger. My car currently is running catless UEL and OFT tune.
My car is my daily driver, not really ever planning on taking it to the track, just want some more power. In the future maybe planning on running e85, but not planning on making huge horsepower otherwise I'd go turbo. Love how the Jackson still keeps the cars stock character where as you still need to rev the shit out of it to make power. The feeling of merging into traffic without having to rev to 6 k with the low end torque from the Edelbrock does sound nice, but really changes the cars feel. The noises and power delivery from the Jackson is fun, and exciting. The low end, off the line ripping torque from the Edelbrock is great for the street. I just can't make a decision!!! What are your opinions? |
Turbo

^^ what he said lol. I you really want to go SC I would go JR.

If you really want a dd supercharger, the edelbrock kit is hard to beat. Nicer looking as well!

if i where to go boosted, with my street status, edelbrock and only edelbrock that said. I have installed this kit and personally driven a few hundred miles on it. and it works rather well. http://www.ft86speedfactory.com/vort...l#.XOPTf6BKh7g |
Find a reputable tuner and have a chat with them, they're as much a part of the equation as the kit itself.

Those are two of the longest running companies there are. You just have to decide if you want low down torque or not.

1 vote for JRSC because the Jackson still keeps the cars stock character where as you still need to rev the shit out of it to make power.
You can't go wrong either way...you've already narrowed it down to the best 2 units on the market currently. |

Harrop. It uses the same blower as the Edelbrock but in a better (IMO) designed manifold. It's lighter, lower, has better cooling, better flow, doesn't need a 'D-box' to fix the MAF issues the Edelbrock setup causes.

Not having to sweat CARB, I'd be torn between JR and Harrop. |
Turbo

Jackson racing, 100%. You really can't go wrong though, you're overthinking it.

HKS
|
If going JRSC why not just go turbo?

Turbo lag? ;) I think EB is more suitable for street and more immediate power. I am happy with JRSC for its more NA like snd that’s just me |

A well designed setup with a properly sized turbo can make the same power as a JRSC with practically no lag and stress the engine less. Or make 5-10% more power with minimal lag and stress the engine the same. Downside really only is heat management if tracking. Just seems like what a SC excels at edelbrock/harrop/sprintex do it better. And what the JRSC/HKS excels at in comparison, a turbo could do better. Still not a bad option or setup none the less just my opinion. |
I have Harrop, so I would vote for them. Power is great, but all superchargers require you to rev them to get the power. Turbos have to deal with turbo lag and turbo threshold, but they typically hit more torque than superchargers down low if they are properly sized; that’s why manufacturers can claim full boost/torque at low rpms like under 2-3k. Superchargers hit peak boost at redline, so even a roots/pos displacement supercharger will still need to be rev’d out to make decent power. The torque down low will be better than a centrifugal supercharger, but not like a turbo could be.
I haven’t driven a JRSC’d car, but I would go with Harrop or Edelbrock. You still need to rev the car out to get the power (when you can’t downshift), but you will appreciate the low end torque. That low end torque puts more risk on the rods, so JRSC will be more reliable. |
obv turbo, but since its between jrsc/edelbrock i would choose the edelbrock bc trq and manifold. It will "feel" faster and pull harder if it makes more trq. With the manifold I am sure future upgrades and power boost will come in handy.
|
One of the reasons superchargers have lower TQ is because we are measuring at the wheels. The engine is still making the TQ and internal stresses are close. Remember some of the TQ is going out the front of the engine to run the supercharger.
With that a small turbo this engine that is sized for 300 to 400hp max, has little lag. Ether supercharger will make you happy, or turbo they are all good. The key is proper tuning to keep from trashing your engine. |
+1 talk to tuners you may use about UEL headers and E85 use and their experience, if that's not serious then you're just judging based on centrifugal vs. positive displacement. The canned tunes that come with them are fine (and what I'm basing my decision off of because emissions)
I like the JRSC because it seems they have better thermal management (track day bro) and none of the drivability issues the Edelbrock had early on which I think are mostly fixed now. But the Edelbrock has that low end punch for traffic and cone dodging. I've waffled on the two for years and am probably still 3 years away from doing it. With no serious driving though and the fact that you probably spend 98% of your driving below 5k rpm I'd think the Edelbrock would be more satisfying. |
HKS V3
Or... SBD turbo |
None go turbo instead trust
|
Agreed the hks looks and operates cool JDM. But HKS,s us customer service blows in the US
|
I'm going to go to go with a edelbrock. The difference is the instant torque and better low rpm torque. The jackson makes better top end power but as a daily, I'm never really over 6000 very much. So I want the most low end torque and I have an auto...
|
If you have an auto I would definitely say Edelbrock. My only complaint about it is the power delivery due to the vacuum actuated bypass valve. Throttle response just off idle is equivalent to stock with the AC running and then you give just a tiny bit more throttle and it is enough that the bypass valve cracks open and suddenly you have a lot more. Makes everyday driving a little more annoying, especially if the roads aren't smooth and a bump changes your throttle position by half a millimeter. Add in an aftermarket clutch that you are going to need and it gets even worse. With a slushbox this won't be an issue.
Edelbrock really needs either an electronic bypass valve or a vacuum one with an adjustable spring so that you can tailor it to your needs. |

No matter how well done the turbo setup is, turbo lag is a thing. It's just physics. |

also looking at torque curve of attached SC (DT) vs turbo (Drift Office) both making 300whp peak, however the SC is making a lot more torque sooner down low. Based on all the aforementioned I don't see how the turbo would be stressing the engine more. also i never stated lag would be non-existent, i even stated on the pros and cons as a con for the turbo, however a good setup (especially if you don't want to make massive amounts of power) can drastically minimize lag to not be that big of a deal.

That's certainly true. I think what they probably were referring to is the low RPM torque output. A properly sized/well thought out street turbo kit will build boost quickly at low RPM and put a lot of stress on the rods if you floor it at 3000 rpm. A centrifugal unit won't do that. The positive displacement units would likely induce more low RPM rod stress as well. |

I have it working on the bench. Have to come up with a way to mount the cable actuation on the SC itself without having to take it off and flip it over. |

^^^ Exactly. The turbo might have lag, yet it is load dependent, so it'll build boost, but the supercharger will just pud along until rpms increase enough to get boost, so it will feel like it has supercharger lag; this isn't accurate because there is no lag, but there is rpm-dependency-delay. In this regard, turbos can lead to lazy shifting, and superchargers require downshifting to get into bigger boost numbers, but when that happens the boost is instant, where downshifting in a turbocharged car will still have some lag, even with a small turbo.

i still cant decide. I dont want turbo. its down two these two,
edlebrock and jackson. I CANNOT DECIDE |
Jackson racing!!!

Honestly if I had it to do over I would get the Jackson simply because you wouldn't need a new clutch since the power is up top. Even an Exedy stage 1 introduces a lot of annoying harmonics when driving; seems unique to this car, maybe because the drivetrain is so light. My STI got upgraded to an ACT extreme clutch and there wasn't an iota of extra noise in the driveline. This car gets a tiny upgrade in holding power and it sounds like I have straight cut gears when decelerating from 3-2k.

1. Flip a coin.
2. See which one your local tuner is better at tuning so you won't blow up your engine. |
