I've decided (now that it's paid for) to tweak the 09 SH-AWD a bit.

I have: The Takeda "choke my top end harder daddy" intake installed.

I have in boxes: RV6 coated PCDs, RV6 longtubes, P2R Polished runners, P2R Thermal Intake Gasket, P2R Throttle Spacer, P2R Thermal Throttle Gaskets (P2R gear courtesy of Throwdown Performance ordered today).

So that gives Intake, spacer, polished runners, pre cats deleted, third cat deleted, and the J Pipe expanded.

On the market, there are a couple very overpriced (IMO) exhaust options that at maybe a peak yield of 10 whp, aren't really what I want, especially at the price. I'd buy the comptechs, also good for 8-10 WHP, but I'm not dropping $900 on mufflers alone, especially since these aren't easily reversible.

I've not seen any pulley kits for the 3.7 that are specifically for it - not interested in underdrives, but mainly lighter.

Brake kits - overkill.

What other go-fast goodies are out there that I should add to my forthcoming "mega-upgrade" weekend?

I'd love to get it up to 400 crank ponies N/A no spray....but I just don't think it's there to unlock without some major headwork and probably a "Stroker" kit with a piston/rod combo to get it up to 3.8 or 3.9 liters....not interested in going there.

 

Maybe have an exhaust shop custom fab one for you?

 

With the above mentioned mods,how much more HP do you estimate you will have? a few members who did exhaust mods claim that the intake performs much better after and feels that there is no loss in the top end that was there previously.

 

The only reason I kept the intake installed is I intended to do all of the additional updates. It may be more valuable with everything else wide open.

I would estimate on the high side, all of the above mods are good for 60-65 whp.
I would estimate on the low side, all of the above mods are good for 45-50 whp.

Across the powerband, there should be a +40hp / +30tq gain - and this car need about another 100whp IMO to be "sporty".

 

We'll have to wait and see what happens with the supercharger project.

Ive been thinking and i havent found anything else. I bet a pulley will be developed in the next year or two.

 

Gibby - you have all of the above done already? What's your thoughts vs stock if so?

 

We offer a stock diameter lightweight crank pulley, manufactured by UR.

http://store.excelerateperformance.c.../i-291887.aspx

If you are willing to purchase the pulley and our XLR8 exhaust I can offer you free shipping to the cont 48 US, which is worth about $100.

Alternatively, you can have a local muffler shop weld up an exhaust system to your liking but it isn't going to be that much cheaper than the systems on the market, unless it's crush bent piping and mild steel. You have to keep in mind the cost of materials alone: T304 US grade stainless steel mufflers, tips, mandrel bends, piping, flanges, collectors, etc Most dual muffler exhaust systems manufactured by major brands like Greddy, A'Pexi, Tanabe, CT-E, etc are over $1,000 and these are exhausts run in large production batches.

The 09+ TL is a small market; building an exhaust for these cars is expensive and when there is such a small market it isn't worth it. So, in reality, the cost of the exhaust systems on the market isn't really that high considering all the factors. Also consider that we are offering a full catback for $200 more than the CT-E mufflers and if the CT-E mufflers make 8-10 whp, how much more whp/wtq do you think is made by an entire catback?

 

dude, there is an ECU out.

20hp/20trq

 

justnspace - I've not seen anything on the ECU for the 4G. You have any links?

im interested in this as well.. i need to improve my mpg..

but i did find this.. may want to contact the company

With the increase in power you are seeking and wanting to get 400 crank ponies on a 4,000 lb car...I don't see how getting an upgraded brake kit is overkill.
The OEM brakes is ok but with the added increase in HP on such a heavy car one will want a better brake setup as well. My .

 

ECU Reflash even....sweet. Now to find someone who can do it, without having to jerk the ECU and ship it out....

 

I would concur with the braking upgrades if I was going to be tracking the car - and they look sick btw - but the majority of the time, it's a commuter and kid hauler. Opening it up in the rare event I get it out on the road alone, might be a quick burst up to 100 on the on-ramp, or seeing if I can keep the needle above 60 on an aggressive Kentucky backroad. Stock stoppers are adequate, and planting the throttle on the SH-AWD is the best way to keep control anyway it seems.

 

No i wish... im ordering an ATLP catback and RV6 long jpipe. Im going to wait on the PCD even though it has great gains.

 

no no no non n nono no no nonon nonon


there is a ECU that was just released for the 3G!
but since we are still in the same J series family, it can be easily ported over.

J&R!
Rodney even asked if any one would like to test fit a turbo on their 4G.
Rodney even said that the ECU can be ported over.

I didnt click that stupid link, but i bet that ECU that ya'll posted is a fake.

on the 3G side, on an N/A TL we gained a peak of 20hp and 20tq!!!

Since this car isnt known for tuners, companies will not spend their dime to figure out how to tune.
Hondata tried with the 3G. but it was inconclusive. too much money, etc.

Rodney is the game changer.
he is having a group buy right now for his ECU.
there are videos of him dyno tuning the 3G with dyno graphs and everything.

here is the original thread about the ECU based off the megasquirt3.

here is the group buy:

If you were serious about tuning your motor, I would pick up the phone and call rodney himself.

For the lazies:

 

Good info! hopefully it can be tweaked to work with the 4G

 

Oh my god - that is awesome! Can't wait to see someone try it on the 4G.

 

an N/A TL-S 6MT fully bolted and this ECU should be making about 320whp.
What do ya'll think about them apples?

the only that sucks is that the 3G is front wheel drive.
but with ya'lls AWD, traction shouldnt be a problem.

this ECU is mainly for F/I folks, but us N/A guys jumped on the bandwagon.

I havent followed the s/c shawd 6mt 4G, but I believe they are having troubles tuning the car.
this ECU will solve that.

 

I have an 07 TL-S A/T that is going to get the same bolt-on treatment if I like how this turns out. I figure the A/T should be able to hit 285whp and be a 20-100 monster for a slushbox.

 

^i'm on board for this ECU.
I'm currently making 240whp with just pcd's and jpipe.

with the ECU and a few more bolt ons, it would be easy to reach the goal of 285.

 

My last bolt on's are the p2r gear and pulley. I'll consider the ECU after getting/installing those. I already feel as if I need a brake upgrade (currently have slotted/drilled rotors, performance pads), getting past 100 is a breeze but I'd like to stop quicker.

 

if you dont want a loud exhaust all the time, but want the power to be there when you need it be, i would recommend putting in an E-Cut, their not that expensive, and you can run single or dual, and with a flip of a switch have a full open exhaust, then flip it close and ride around stock again...i was thinking of going that route, but i'd rather just have the xlr8 cat back..

 

btw just wondering how the 3g ecu would work even being ported, since the 4 g tl runs both Map and Maf sensors...
