Who would like to boost their 8th Gen? Engine and performance mods to make your Accord more racekar.

[ivan_j35z3]

I've been trying to convince Hondata and CT Engineering to make a tuning solution for us and a boost option. Although V6 Accord's has nice bit of power already, imagine how it sound be with a nice safe Supercharger. That sexy supercharged noise sounding on that large V6 engine! I know. Anyways, Hondata skipped our gen for tuning and went straight to the 9th gen tuning (https://www.hondata.com/) because they claim it calls for better "performance" although the 9th gen Accord's have slightly better performance with the direct injection, specs are almost dead similar. What bothers me is how they made a Supercharger for the V6 J Series TL but not for our J Series Accord's. I don't get it.

Anyways, the purpose of this thread is to see how many people would be interested of purchasing a boosting solution if they made one for our cars? I'm guessing it would cost around $5,500 to around $6,000 for the Supercharger with the tuning. I'm just guessing it would be around that because the tuning for the TL is $695 and the Supercharger is just under $5,000 for 65HP to the wheel or maybe more. I'm going to make a list with everyone's name that would be interested of buying and send it over to Hondata and CT Engineering or at least give them a head count of the possible demand. Maybe they can see the demand in it and possibly make one. Let's see how far the list goes! I know if they really want to make something for our cars then they will.

You know I'm interested! 1

[jman64cola]

I've always been interested but for the k24z3 but the cost of it is becoming harder to reach. So I don't want to say I'd be buying it. Also most on here already have ktuner but boost suport isn't released yet.

Thanks for the reply bro

I think it would be a good time boosting the V6, but I'm scared to find out what all it would cost at the end of the day between supercharger/turbo, trans upgrades, forged internals, fueling, etc.

You're right. That's why I would prefer Supercharge for the less maintenance. I'm up for the challange

I certainly would. I have posted a thread over at the drive accord forums like this one, but its a ghost town over there for "true performance interest". Most people care only for floormats. A majority of "performance threads" are related to muffler sound or intake sound and throttle body spacers.

There just isnt good enough interest for major companies to invest in actual "race" parts for our cars. But this isnt really a problem per say. It just requires that we have more custom solutions designed for our cars individually.

For tuning
I have a fear that because of the lack of interest in performance gains, that Ktuner wont complete his tune allowing boost tables. He still hasnt released anything for larger fuel injectors, which is also vital for boosting, and has even stated he doesnt intend to give more tuning options unless people are interested, but he has also noted that he only has seen a couple of people who want to go this route. If he doesnt give us more, then we are somewhat back to square one, right? I dont know enough on the subject to really go into detail, but I will guess that perhaps that "AEM FIC" controller may come into play for those of us who want to boost, but its hard to say whether this alone would be enough. Something tells me the answer is no. We can continue to wait for him to give further news, but he doesnt release information on what hes currently doing, so it may be next week, next year, or perhaps never that he updates the software.

As for actually boosting, a speed shop should be able to fabricate what we need.

For Turbo

A twin turbo setup could be built by making a modified PCD that mounts a turbo on each side of the V6. There are actually builds like this. Do a google image search for j35 turbo... Only issue is the cost of this. A single turbo may be hard to fit somewhere without an elaborate and expensive custom turbo exhaust manifold. So either way youll pay for this. Not to mention its hard to say how well the engine would act around this much additional heat buildup in the engine bay. This car is notorious for acting very strange and flat out slow when it gets hot.

For supercharger

This is the route I think I want to go. A vortech supercharger is centrifugal. If you dont know what that means, its basically a belt driven turbocharger. Not as good as a Twin screw superchager by any means, but should give a nice amount of mostly top end, shouldnt be too expensive, and better yet should be higher in efficiency and low in heat buildup. So fuel mileage shouldnt suffer much. I can see mounting this either at the top next to the power steering pump or down low by the A/C compressor. The main cost of this route will be a custom CNC'd mounting bracket to install the supercharger, as well as proper mathematics to ensure it spools at the correct speed.

Twin screw superchargers just have no where to fit unless you cut your hood, but this to me would look incredibly rice...the engine is obviously sideways so everyone who knows anything about cars would know its FWD driven. Also the cost of this would be insane for a custom intake manifold and all kinds of custom parts. BTW, CT Engineering, the one they offer for the TL? Its a roots type....so very inefficient and hot. It apparently can fit our cars. But IDK if its servicable, upgradable, ect. I just dont see it as a viable solution by any means... Its not much better cost wise vs another option sitting at 5k to purchase, but it is available for almost immediate implementation into our engines.

Closing thoughts

I think we should wait a little bit. Until maybe June before doing anything drastic regarding having a speed shop jerry rig something in hopes that Ktuner gives us a usable update. It brings me a lot of hope considering A) He has to fix the speed limiter not being disabled B) The tune is still considered "Public beta", and last I asked him about fuel injectors, ect, he used the word "not yet"

I am paying off this car officially 100% on Friday, so next month I will be going crazy on custom mods, starting with true duels, and finally get around to posting a build thread.

Hey man this is awesome stuff! I hear everything your saying man. Even though turbo would be awesome, it would be too much of a headache and maintenance to maintain. I'll just be happy with a direct fit supercharger kit. Good instant power, less heat buildup, and more reliable. I've been trying to convince Hondata and Nate form CT Engineering to make a tune and boost but doesn't seem like they want to.

I didn't know K Tuner has thinking of making something for us? I saw the product but didn't think it was for us. Can you inform me on what's going on with this? I though K Tuner only made stuff for K Series.

Send me a PM Apple Slicer, we got to keep in touch and make this happen for us and for everyone.

[Apple Slicer]

A few months ago ktuner released a tuner for all 8th and 9th Gen accords both v6 and i4. Auto and manual. Only issue is he has not yet released the program out of public beta so it still lacks fuel Injection sizing and boost tables.

So for the most part we are go for tune. Now it's just a matter of one of us getting the time and money.

Btw: as far as heat concern goes, heat will get us either way. I've read a lot about J builds, and these engines are very susceptible to heat regardless, and superchargers, mostly twin screws vs centrifugal, make a lot of heat like turbos do.
