Marcus of Heeltoe is my main mang!

“Copped” the new 3” ATLP J-Pipe

Rain or Shine, that new M90 is goin’ in!

This S/C did so well for me!!

I will miss her. She will soon sit pretty on my mantle.

Is your alarm clock the sound of a supercharger?

Acura TL Builder

Ha! I’m not paying $1.29 for a supercharged v8 alarm tone!

Acura TL Builder

Out with the old, in with the new!

Where’s Maj?

Zip tied and padded Vulnerable areas of the tranny cooler tubes with rubber pads.

After remounting the tranny cooler, it fit like a glove!

Now there’s room for the Heat exchanger!

Acura TL Builder

Always room for improvement!

Can’t wait to hear it whine.

Looks like I didn't stay on late enough yesterday, I was waiting to see this! GOOD LORD THAT IS TALL. I hope you're not a shortman like me, half the reason I started brainstorming the no manifold design is the age old "I can't see the tree past my supercharger" adage.
What are you using to cool down the ZZP intercooler?
I see a tranny cooler.... are you automatic and running an m90????

Acura TL Builder

I’m 6’2”, so I see over it. Though it’s so tall! You don’t forget it’s there like the Comptech.

I laughed my ass off thinking about your adage as I installed the charger yesterday.

I have a heat exchanger that will be water cooled for cooling the intercooler core.


Hell ya I’m running auto on the M90! Think it’ll handle it after 175k original miles?

the tranny cooler is a godsend for the TL. Highly recommended!

Acura TL Builder

First Start!

Acura TL Builder

First test drive!



Stayed out of boost. No check engine lights, no hiccups.

My guess for tuning tomorrow is the 550cc Bosch injectors will be maxed out.

If that happens I will order 800cc injectors and keep the 550cc as “Comptech injectors”.

What are you going to do for a hood?

oraclem20

Praying for you. You are on the new bellhousing in that 08 right? If so it should be fine, for a few hundred more HP.
Sounds good! Will be waiting to see how your results are, haven't calculated the ccs needed for the m122 but i'm guessing it'll be 1000. What size pulley are you running on that thing currently?

Exciting to see it go, are you planning on fabbing a plate for a tensioner? I plan on using a spare serpentine or timing belt tensioner on the front side of the belt for mine, IIRC anything over 5000rpms and people were getting some fair slip/boost drop on the prank parts kit without a tensioner.

Acura TL Builder

I bought a WDP OEM hood that I will cut into.

Acura TL Builder

Thanks man! I’m about to head out to English Racing for my 8am appointment! Put in 43 hours since Friday night just on install(including all four engine/tranny mounts).

900-1000cc sounds right if your run it on gasoline.

I’m running ZZPs smallest offset pulley. 3.4”

Your going to use more than a stock tensioner? I got a tight belt, hopefully I don’t encounter belt slip. We will see!

Acura TL Builder

This was so fun to install!

Going to cut the hood I reserved for the M90 Kit after tuning. It’s raining a bit so I put an old shower curtain I had in my shed to keep the rain out. Put the engine covers over it to help keep it in place. Think it will keep the rain out as I drive slowly to the tuning shop?

Check out that hole in the bumper! Going to make it look better after tuning.

oraclem20

Excited to hear how it went! Rain or shine, hope you got some results!
Are you running an underdrive pulley on the crank or stock diameter? Trying to figure out your possible boost level. I'm glad you reminded me of those larger offset pulleys, the largest non offset I could find for m122 was 3.4, which puts me at 15 lbs of boost with my underdrive. A little aggressive for the first tune! The 4.2 should put me at a much more moderate 10 lbs @ 7500rpm before heat losses.

If you're running the stock size crank pulley you could be pulling 13 psi at redline. Be careful! You are running outside the efficiency map of the m90 however, so heat is going to be your enemy, good thing you have an IC! Without it you'd be looking at 40% efficiency, bringing that back down to 6psi. Looking forward to your results!
https://www.superchargerforums.com/a...28485-gif.553/

Yes I definitely do plan on adding a tensioner. Considering if the belt slips I may go from 15+ lbs to 5... yeah i'll be adding a tensioner. It's too easy a fabrication to skip for the extra reliability. Plus with the belt path I'm looking to make it wrap a few more degrees, I think going between PS and alt only gives you 60* of contact area, which just isnt enough for something pulling the torque of a SC. I'd like to tuck the belt path at least in the front to have a near vertical drop into the engine bay (half way for looks, could do less), however I'd also like to get some better wrap angle on my alt. I'm running a HighOutput 230A alternator with a tiny 1.5" pulley and some audio. That thing can slip on it's own trying to ask for 200A.

Acura TL Builder

I’m running 9.7psi on the 3.4”. Perfect daily power level.

The IC gave me a consistent 113F IAT. But I have a lot of air in the system so it would have been considerably cooler. This means I’d be at about 10-10.5psi boost and cooler temps! Also perfect daily PSI.

Thanks for the supercharger forum link. I didn’t know that existed!

Acura TL Builder

I don’t use an underdrive or anything aluminum(lightweight), as the forces may bend/warp it over time.

oraclem20

From what I remember anyone over about 8 lbs had problems not blowing up the engine due to exhaust gas pressure. IIRC you've had your heads done, and i'm currently reboring my heads quite a bit in anticipation for this. I think there's nearly a 30% difference in exhaust port size on the heads at this point in time, i'll get some pictures up here if I clean it up past the carbide burr stage.
That being said, good numbers! I'll definitely be running the 4.2 at first (2.5 currently on there would put me at 25 lbs XD), how much fuel did you need to calm down your 10psi? That 113 IAT seems like a compelling argument for the IC, but that's far above my budget. At least the exchanger itself is, where did you find yours?

Acura TL Builder

Exhaust pressure isn’t an issue with the J until past 650whp. Even then you only loose power per PSI due to flow inefficiency and exhaust valve size.

I don’t think 8psi is much and shouldn’t blow a tuned Jseries.

8psi was blowing Comptech engines a decade ago due to belt slip with High Boost Pulley and the lack of solid tuning capabilities for the platform at the time.

The heads on both my cars are going to be done, starting with the J32A2 heads that are going onto the J35A8(Type-S) block. Then I will port the J32A3 heads.

Currently I have a “Stage 1” ported n polished set of J32A3 heads ready to go, but I’m saving those.

I bought my pulleys and IC from ZZP, great people there

PnPing is an art form. You have to be one with the airflow. It also takes an outrageous amount of time to do a good job. That said the benefits are smooth

Acura TL Builder

I just took the car out with the Wife for its first drive.

oh. em. gee.

This car pulls hard with no drop off in power until 140mph, wherein I ran out of road.
It does it so smoothly it felt like 100-120mph.

Even though the Comptech was up to 330whp and only 21whp difference currently between the two, the M90 pulls harder over 100mph.

This tells me that there is plenty of airflow and when the 1000cc injectors and 450lph Walbro pump are installed, we will make Mo’ Powa’ Babeh’!

The intercooler in the front and the ridiculous muscle car style blower on top make it quite an eye catcher. Two cars with wide-eyed passengers gave me thumbs up in the few minutes I drove it.

The noises this car makes now is so nice sounding!

Stood next to my tuners legendary 1100whp J32A2 as my car was being tuned to my right!


Love seeing this system and picking up tips for my own builds!

Nice results! 350 ain't bad, and you've still got PSI to go, did you get to see if the injectors ran out of overhead?
I just talked with ZZP and apparently they make 0 pulleys for M112/M122/TVS, so i've got a few other brands i'm talking to. I cant use this 2.5" pulley, it'll pull 25psi!
Interested into how you're planning on getting the walbro in place, was just looking at a german DW400 who apparently outdoes the walbro 450. Trying to choose 1000ccs myself, who did you end up going with?
Great to see a J series that has max torque at 2500 rpm, I would have never thought i'd live to see the day!

and dude, that civic build looks legendary, what is that a 80mm turbo???

Acura TL Builder

The injectors ended up being at 102% duty cycle before he dialed it back.

The Walbro will be installed just like the same Walbro that came with my Rotrex kit. Andy told me to do it the same he did. Chop up the cradle and cut a hole in the bottom for the sock. I tried to not cut a hole at the bottom of the cradle, but It’s the only way I was able to get it to fit.

Heres a low priced injector I was able to find. I’m currently running the 560cc from the Audi S6/turbo And they work well.
https://ksm-motorsports.com/products...96lb-high-ohms

oraclem20

This was one of the same I was looking at, is that the set you have coming in?
Geez so the injectors were on full blast! Very well may be able to get up to 400 with the larger ones.

That's what I'm seeing for this DW400, except cutting a hole for the sock however that may depend on how the fitment is. My only concern is pigtails/wiring being correct to not need to splice wires in a fuel tank (eek!), are fuel pump plugs universal or how did that get worked out?

Acura TL Builder

You will have to use the one that comes with the aftermarket fuel pump kit. But I use a PTFE tape that won’t degrade when subjected to fuels.

The 1000cc will be good for 450-500cc on the J.


It was recommended to me to use a relay and wire the fuel pump directly to the battery.

Acura TL Builder

I will remove my entire aftermarket fuel system from my “Rotrex kit” on my Type-S and use it on the silver car.

The pump, injectors, and return line, fuel lines are too small for the numbers I’m envisioning on the Type-S after turboing.

Since the injectors are 1300cc and the fuel pump is 450lph. It will be plenty for the interchangeable boost systems on the silver auto TL.

EBC yellow track pads on their way!


Car is ready for the track this Friday!

Lets see if I can best last years lat time with oem pads, dry rotted tires, and the Comptech S/C.

Congratulations on your successful M90 install.
Maybe you can apply something like what's on the link below to hide those sharp cut metal edges?

Is there a way to remove the OEM intake manifold and making an adapter plate that bolts to the runners? I don't know if I missed the point of keeping it.

Acura TL Builder

Thanks for the suggestion Zeta!

My neighbor said he may have some of this material at home. If he doesn’t find it I will purchase this!


Thanks for the paint suggestion. I’m going to have the Gerzy Bear bumper painted later this month.

Acura TL Builder

I could do that, but I was under a time constraint to tune June 9.
otherwise I would have to wait 6-7 weeks to to retune.

Also didn’t see why it’s needed when I can cut directly into the runners. Eventually I will do that. Things can always be improved.

Acura TL Builder

Ohnoitspiter had his Rotrex kit dyno’d today and was left very disappointed. He had the Stage 3.5 kit, then bought the largest C38-R Rotrex unit, rebuilt his fuel system again, built his engine.

He has every supporting mod and then some. No expenses spared.


I would be heartbroken to make these numbers with a kit advertised to get 900-1000hp.

HP & TQ ain't easy. These SUV motors were not designed for this tomfoolery.

I bet the key is whatever is causing that break-up. Fuel + Air + Spark + Compression @ Timing is a simple equation but each component has 10,000 variables. The dyno trace shouts that something is wrong above a certain RPM but we don't know what. Spark blowdown? Port & polished intake runners wetting under boost, leaning the mix out? One coil vibrating loose? Fuel pump choking from voltage fluctuations? Hidden table in tuning maps turned off/on/backwards/upside down? Could be any one of a jizzbillion things.

Acura TL Builder

Thank you Sir!

Just wondering if you are going to update your youtube with any new in car pulls / drive by video of the M90?
Kinda wanna hear it scream a little.
