You can have 2-3psi at anything above 2500rpm anytime you step on the throttle and it grows gradually, depending on load, until full boost is reached. In the old dyno sheet, I didnt even floor the gas until the car was past 3000rpm, and we got full boost at around 4000wpm so that gives you an idea of how quick it is. It is by no means like a n/a V8 but it does respond like stock until boost kicks in. The greddy is quicker but there is no way to generate 400whp and have boost at 2000rpm unless you have a complex sequential setup with a turbo like ours and one like greddy's.

Considering that you're usually cruising around 3-4k anyway, that sounds quite reasonable..

eviltwinkie

indeed...would make living below boost pretty easy...if that were possible to tell my brain to do...

sure makes me wonder how it would feel with the feed gear...

put those two together and your MPG drops like the panties of a sorority chick at a kegger...

wow...................the price is really good.........arggg......... need money.......if only I didn't blow it all on my gf..

I think street performance will be slightly hindered. 1/4 times might improve slightly because your coming out of hole but I dont see any improvement on the street, maybe a loss. If you are going to get a differential, get a 4.10, that will make performance way better. The gears are too short as they come from the factory, your run out of first gear with the first 3psi of boost and will never reach full boost. Turbo cars, especially the ones with big turbos, depend on engine load to spool their turbos. You should always want to higher your differential ratio because it makes it easier for the engine to move the car but not to the point where it reduces load so much that it doenst spool the turbo. Instead of running with a 4.44 and 8psi in first and 12psi in second you end up with a 4.777 but you barely make 4psi in first and second makes it to 8psi. Which one do you think will be quicker? And yes it is that drastic. The FD people go from 3.9 to 4.10, there can be an improvement here but if they went to ours they would loose performance on the street. And dont forget that the FD has longer ratios in the transmission so a 4.10diff in ours would still yield less mph per rpm in any given gear. If you're running slicks then you will gain performance when out of hole because you will stand on the throttle and just let the clutch out so you will be under boost quickly but how many times do people do this with their cars? In my opinion, get a lower diff if you are going to get one, a 4.10 would be a perfect compromise.

I have always felt that the 4.10 would be perfect for FI applications...

I remember you discussing that you have a solution for spark blowout for above 340whp. You are making pretty high claims with this kit and yet to release anything about the spark blowout solution.

What is in mind for this solution?

What other products are you planning to release to compliment your kit?


Having been one of the first to reach this higher boost and obtain more power out of my current kit, knowing what to expect with these higher boost levels I am curious what your thoughts are for above 400whp-550whp range?

Did you get your car back?
If you did let me know when you come back down to these parts. I would like to see your setup in person it looks a sweet in the pics. Must be fast.

In working with one solution(the obvious one) we came across a another simple solution that allowed boost levels up to 17-18psi. The solutions are done and they work, we are just working on the process of getting them from the prototype table to an end-user status. I will not go into detail as to how they work just yet

The plan is to release some info. that will allow the average owner to perform a mod on their own if slightly better than 340whp is desired. We will also offer a complete Ignition upgrade kit that will probably be good to beyond 500whp.

+1 for good info...

Nice!!!

We took some new pictures of the components and will be posting them on the website as soon as possible. Chris will be installing a kit within the week and we will post many photos of that installation as well.

I read on your site that you strongly advise the customer of this kit to have the car tuned. How dangerous would it be to not do so and run on the stock map that you can provide on the Interceptor-X?

mike1324a

you should always get it tuned no matter what, however sometimes it takes a little time to get into a shop and get it tuned so think of it that way. How safe is it to use UNTIL you can get it tuned.

truemagellen

We ship with the springs set for boost in the 7-9 psi range which with this turbo size and our conservative map is under most conditions safe (if you have nitrous and the kit is an example of probably not safe ).

That being said we always recommend you tune so you can maximize the performance and reliability of your Turbo 8.


The Interceptor-X/Microtech base map created for use with the Esmeril Racing Turbo was created by a skilled tuner after many many hours on the dyno, and on the street. In addition we had extensive consultation with a Microtech distributor who reviewed our maps, tuning, and helped us optimize the settings/setup for the Microtech. With your included initial base map programming we will optimize all settings for use with our kit.

Question for you............
With the upcoming upgrades and options you will have with this kit, do you recomend the EMU or INT-X. I know this will prob be an opinion but just curious. Just want to make all the right choices before i buy your kit..........
Thanks for the help!!!!!!!!!

eviltwinkie

Are you guys going to actively pursue getting the kit to work with the Cobb Access Port as soon as it is released?

There might be a problem with the Cobb Access port in turbo applications. It alters the stock ECU which is fine for N/A and supercharger applications(flow varies linearly) but because the stock ECU doesn't have a map sensor in the intake system it will perform poorly with turbo because turbos are not linear, in higher gears boost will come one sooner than in lower gears(its not proportional to rpm or throttle position). This will make it hard to tune a car with only the access port as a tool. It will undoubtedly be an awesome tool to manipulate other settings, like the APV opening time/criteria and maybe even the TCS but I don't see it working as well by itself with a turbo. The ideal setup would be a system with both MAF and MAP working together. We will for sure get our hands on one and see what its capabilities are but from where I sit now this is what I think. Maybe I'll be proven wrong and tuning with MAF alone will not be a problem but I am not to sure of this.

If you are planning on getting all the upgrades, you are probably looking at high 300whp to low 400whp levels so the Int-X would be the way to go. And no its not an opinion only it just works a little safer at high boost levels because it doesnt vary with the stock ECU.

Why dont you take advantage of the holiday special and buy a kit and an int-x for the price of the kit with the EMU....

Just a thought

I'd spend more time researching that subject... more then a few turbo cars like the the Evo are maf based from factory and have no problems

Red Devil

Also for the Subaru, Cobb has a 3 bar MAP option that can be added to their tuner software.

Will the RX-8 get that option, we'll see...

"I'd spend more time researching that subject... more then a few turbo cars like the the Evo are maf based from factory and have no problems"

I am aware that some systems do work well with FI and are MAF based but this is usually the case on OEM setups which are tuned to perfection at the factory with unlimited data measurements of all possible scenarios. Most people don't have access to engine dyno's in rooms with controlled environments. Here is a link to a thread on an Evo forum:

http://forums.evolutionm.net/showthread.php?t=129546

As you can see there are pros and cons to both, I just think its easier/possible to tune a MAP setup by the average Joe with limited data(AFR and Boost) that it is to tune a MAF system which might or might not be possible, not to mention that if you tune a MAF system and then get an intercooler piping leak somewhere the car will just die on you. If you tune in a given range of temperature/humidity and then drive somewhere into a completely different atmosphere you are more likely to have variance in how your car behaves. Evo's don't have this problem because their engines got put into an engine dyno and subjected to every possible environment on planet earth while they ran using FI.

Its a preference thing more than anything but like I said maybe I'll be proven wrong and the RX-8 computer will take well to FI on its own with the Cobb system. I'm sure we will test it out for sure. Also, dont forget that the Evo system is MAF based but it probably has a few other sensors that measure intake temps, humidity or god knows what, it was designed to be FI from the get go. All I can say is; we'll see.

Again this is only my opinion.
