2009 Accord Coupe 6MT Dyno
Hey guys, long time forum member and have had a couple Acuras. Figured I'd post this here since the 8th gen Accord is most like the 3rd and 4th gen TL.
Richie developed the longtube Jpipe and a test set of PCDs for the 3.5 Accord V6 so I told him I would test for him. Only mod I had was Injen CAI and dynoed 237whp and 224wtq. After the installation of the Long Tube Jpipe I dynoed 263whp and 237wtq. (Had previously dynoed 260whp and 239wtq with 3rd gen TL specific ATLP V1 jpipe and testpipe) After the installation of the Precat deletes I dynoed 279whp and 253wtq. All on stock exhaust. Hoping a few more mods will enable me to crack 300whp. There are a couple 8th gen Accords that gained 25+whp with the P2R ported runners and UR Lightweight Pulley. I'm going to attempt to get all of this power to the ground first.
Going to load the dyno sheets this evening hopefully. They are on my flash drive.

Wow. Those are really impressive numbers. What dyno was this on?
Regardless of numbers the gains are SERIOUS! Damn that 3.5L really responds to mods very well. And that's with stock exhaust! If I were you, I'd make sure to get a 2.5in exhaust to mate with the 2.5in collector on the Jpipe. I made the mistake of getting the 3in exhaust w/2.5in Jpipe collector (soon to be taken care of
).
25whp from the ported IM runners? Jesus. I gotta get on that for my lil 3.0

Yea its a good motor, technically the same as the Type S except the Accord has lower compression. Its ashame Honda restricts the Accord with so much stuff to get higher MPG. This was on a dynojet. I'm def gona get a 2.5" catback to keep diameter consistent and split to 2.25".
And I was quite surprised to see that guy gain 25whp from runners and pulley, especially from that particular 3.5. (The 8thgen 5AT 3.5 is different from the 6MT 3.5 since it has VCM, they don't have the same kind of VTEC)

Sounds good man. I would'nt be surprised to see 285/260 with an added exhaust, maybe more.
What was your trap speed when you ran 13.8? Have you been back to the track since just your CAI?

26 horsepower gain with the Jpipe? Jeez I knew these cars responded very well to exhaust mods but... jeez...

Damn that's a great trap speed for basically stock! The 8th gens really are a good amount faster than the 7th. 
lol.

Thats quick, but I have a buddy that has a 7th gen 6sp that put down a 14.6 in the 1/4mi. Then later on put down a 14.41 on a stock accord sedan. Trap was 98.xx. But he really knows how to launch. The new accords are quick, but they are also heavier. So the added torque helps alot. But if you mod the 7th gen alot and know how to get out of the hole, they put down better times. Me, I couldnt get out of the hole for crap.

7th gen 6-6 will never put down better numbers or times than the 8th gen 6-6 with same driver. My car only weighs 3400lbs. 7th gen weighs like 3300lbs. Thats only 100lbs with more H power and TQ. My 8th gen 6-6 ran 13.9 stock. I don't see how a 7th gen could do that stock. Maybe 14.1 but not 13s

13.9-14.1, the changes are pretty academic. Same driver, same condition car, same track, IMO it would be a coin toss.

Same conditions/same driver, the 8G 6-6 will win every time...it's just a faster car. I always had a lil grudge for the 8G because of this lol . But I'm over it now.
L what did you trap stock?

Very close to 103mph. It was like 102.8 or .7 and hey no reason to hold the grudge. At least you guys can have LSD, supposedly the LSD from the 3G TL and TLS wont fit in the 8th gen Accord because the gearing ratios are different or something like that. I stopped listening after I heard "it won't fit" LOL The 8th gen is geared pretty agressively. Allows for you guys to get better MPG too.

sonnick all u need is a 3.6 build and u will be rolling past 8th gens . common sonnick u know u want to!!! plus since the 7th gen accord has less drag than the 8th gens u can do it.

Thsi is correct, but as I'm sure someone will state all dynos are different. best thing to do would be for both a J36 and a J35Z3 (both 6MT since the J35Z3 only comes with that) to dyno at the same time on the same dyno. I'm sure if I port matched the heads to the lower IM runners to the upper IM runners to the TB like the J36 is with pulley and full exhaust and intake it would pass it powerwise. J36 is still pretty powerful/efficient to be an aftermarket built motor.

^^ yeah i hear where ur coming from. however j36 dyno at around 270lbs+ torque compared to your 250lbs torque. your current 8th gen av6 6mt makes as much torque as the 3.3 liter build paul makes for the 7th gen coupes in a automatic. worldononefinger in his automatic 7th gen 3.3 liter makes 250lbs torque and 260-270whp consistently.
what dyno shop did u go down to in D.C.? if i can find time to go down to it this winter break before my twin turbo i will run my car on the dyno u run ur car on L's TL, so we can compare #'s.

plus L's TL, have u tried any other tuning sources? i mean i know the aem fic works wonders for the 3rd gen tl and 7th gen accord, u should try it and see if it works for your car.

Damn 103 stock
I can't even trap that with full bolt ons
I also have a lot going against me at this point...will go back when everything is in place
Kevin's J33 also has every bolt on plus ported heads/TL-s cams/11:1 CR and a tune. So comparing that specific J33 to a CAI/Jpipe J35z3 isn't fair. The new Accords are definitely underrated from the factory and respond very well to bolt ons.

I go to ISP racing in Beltsville. They are pretty cool. There are a bunch of 600+rwhp Supras and 500awhp evos up there all of the time tuning. And I'm cool with the owner, he's got a twin turbo Viper, its sick. Just hit me up whenever you want to go.
yeah i am running a scanguage 2 and found that i get about 39-40mpg on the highway. other members on accord websites like kschwiggy who have j35/j36 have also gotten the same mpg. i then get about 24-26mpg in the city as well when im not flooring it all the time.
plus L's TL, have u tried any other tuning sources? i mean i know the aem fic works wonders for the 3rd gen tl and 7th gen accord, u should try it and see if it works for your car.

LOL I only drive that way occassionally now. I get 32mpg Hwy and 21-23mpg city consistently. The Final gear ratio is shorter for my 6MT too compared to the 7th gen and 3rd gen TL. @ 80mph I'm hovering over 3k rpms whereas the 7th gens are hovering over 2250rpms
Once I get the runners and pulley and catback I'm sure I can clipse 270wtq. I still have the stock catback on.

Na man, I need to tune it. I'm running like 12.1 AFR @ WOT and @ idle around 14.1. I need to get WOT to 13 and idle to 14.8-15.0. Running REALLY rich. I may toy with bumping up compression too but I don't know how the ecu will respond to that.

what kind of dyno does Beltville run?
nm.... it runs a dynojet i checked them online
your running rich too? same here luckily my car isn't my daily driver since my wot afr goes down to 10.9-11.3. my idle is at 14.6-15.0 which is nice though. since paul has been mad busy i've haven't had the opportunity to get my car fine tuned yet, my goal wot afr is 13.5, and 14.7 my ideal idle afr. however, i really wasn't going to bother with my tune since 11s-12 is good wot afr for my boost install in the next couple weeks, but if i can get paul to send me a new fuel map even to raise my wot just to 12.5 i will def come down there!!!

if u want more torque i would say get a mdx spacer, im not sure if it fits 8th gens or not though, in itself the spacer yields about a 6wtq increase.

yeah the tune will be tweaked when turboing. the WOT im gonna try to go with 12 afr since that is what i beleive libert was running on his turbo tl. you are correct though, i definately need to dump more fuel when im at idle.

Bump, For some reason I cannot find actual dyno numbers for the ported intake runners so I wanted to see if you did this mod yet and results. I currently have a completely free flowing exhaust, takeda sri, and p2r tbs. I wanted to know if the ported runners will kill my top end or not. There are a few threads but its mostly bickering and few tangible numbers lol

I haven't seen a dyno of the ported runners before/after. I will not kill your top end though. If anything, you will probably gain 3-4whp up top. The OP is rockin' the RL now FYI...

Oh nice! love the rl haha
just trying to find dyno numbers since some people say you lose alot of top end when combining ported runners with an mdx spacer and freeflowing exhaust. I guess I may have to be the dyno guinea pig hahah I do not have the mdx spacer though so Idk how relevant the claims are to me lol

As Justin said, the MDX spacer will cause you to 'lose' top end. More accurately, it will shift your powerband to the left, meaning you will have less top end but more midrange. Without the spacer you should gain top end with the runners.
