Edelbrock vs Jackson Racing

[Luftwaffel]

I'm wondering how one can claim the Edelbrock kit is unreliable, given that it's been out since breakfast.

Also the issues with it are almost certainly install or underlying issues.

Neither does the CSG car (granted with full bolt-ons and E70)

I have a 15 BRZ and I chose the c30 Jackson kit and I am super satisfied, did the install myself and had it tuned at PSI here in Tucson. I have an Invidia N1 and Speedfactory ft86 UEL catted headers the rest is stock including wheels/tires/clutch. Not much wheel spin unless you drop the clutch or do a take off and depending on the tire/road temp. The only issues I have ran into is putting the front bumper on and I have to manage how hot the oil gets (havent invested in the oil cooler). 10/10 would recommend, I go mountain carving and if you are an avid driver which Im assuming you are you will not regret this kit.

It's very pleasing to just mash the gas in any gear at any speed and accelerate at a pace that puts a grin on your face. We did one track day with the car so far. We dont even come close to pushing it at our level. Other than dealing with some cold start issues on e85, in the short time we have had installed all has been well.

That being said. If the frs was my car I would have bought the Jackson kit. Because I feel it would match my stile a needs a bit more. I am currently working with my shop to build a custom rotrex supercharger system for my celica.

This was the very reason I ended up with the Edelbrock after being on the fence between the two for a while. This is my DD, so street driving and day to day livability was high on my list. I wanted a "bigger" feeling engine, something I can just "stomp and go", no need to down shift to pass, go up hill, etc. Sure, city mpgs suffered, but freeway is still close to stock (currently 23 city/28 hwy, used to be 25/30).

Have not had any issues so far and have been very happy with Edelbrock's customer service. My kit was one of the first few ones and was missing a couple really minor components (zip ties, sound tube plug, etc. nothing I couldn't go without), I mentioned it on the owners thread and was contacted by them and sent the missing parts. Another instance, I posted a log just for the hell of it, one of their engineers noticed something off and contacted me and sent me a "fix". Mind you, none of these were initiated by me.

Over all, car makes me happy and I'm not worried that I'll be left stranded on the side of the road, and I'm good with that. I am yet to dyno it and probably never will....

Very true, only time will tell. Just need more data points. OP, don't let the extremes (both good AND bad) sway you one way or the other. Do your research (which it sounds like you are) and make an educated decision based not on your "wants" but on your "needs".

Same way goes with CARB certification. I admit, I'm also a little worried that its still "pending" but I based my decision on Edelbrock's track record of getting these certified, which is true for all their kits so far.

Edit: redacted comment regarding JRSC CARB

Actually When the JRSC kit started shipping 3 years ago. It already had a CARB EO. It was never in a pending state.

I stand corrected, doesn't change my opinion though

@sw20kosh's data.

On a 70-75F day, with an experienced/fast driver, using the JRSC. High line = stock hood. Low line = with TrackSpec hood louvers (more flow = more FMIC cooling = lower IATs... and because air-air cooling results are very immediate, it's easy to see):

It doesnt say or show what ambient is in those datalogs but from the datalog I saw from Sleepless car on track, IATs are more like +30C over ambient (average).

Perhaps he has an oil cooler mounted up front.

40F day:

My decision was primarily because I wanted a PD blower rather than centrifugal, and I personally think that should be the first decision made before getting into brand, since they willl drive differently. After that, I weighed the pros and cons of both of the ones I was interested in, the Sprintex and Edelbrock. I found the Sprintex 210 to be a bit small, and the 335 too big, with the Edelbrock as a happy medium. I didn't care much for the long intake tube either... just seems like a lot of opportunity for heat soak. And, like many have said, I'm pretty confident in Edelbrock obtaining CARB, so if I move to CA, no problem.

I just hope the rotors will not delaminate like my mp62. But I over pushed that blower and did not have a intercooler.

Based on your application, have you tried running E85 for a little power bump? You can try that first without investing a large amount in a FI kit.

I do think that one very important factor to consider when potentially going with a modification is how much of a benefit you will get from it with the amount of money you put in.

I'm sorry can you clarify your last paragraph? Not quite sure if I'm reading it right

I think that based on your driving application that you should try the low-cost (OFT and E85 tune) alternative of trying E85 for a gas tank or two.

What I was trying to say is that do you think the amount of performance gained from a FI system is worth the money to you?

ah i see,

So from my understanding a baseline stock brz is around 165 WHP, with e85 FlexFuel kit by itself and stock everything else i should be close to 200? 190? and with FI (edelbrock) i should be around 250 WHP. probably close to 1500-2000 for parts and install on the flex fuel..close to 6000 for FI and install. i see your point but i only have one e85 station close to me here in SOCAL. would be kind of a pain in the ass to go e85..but flex fuel allows you to run blends of 91octane and e85? I'm still not very familiar with how e85 works
