hey guys would be really cool to get a post with all boosted 2.4s setups, dynos and quarter mile times etc. Pics would be good too.
thanks

 

I'm a 2.4

 

So here is my setup to start with:

2.4 LE5 standard transmission
- 2.9 supercharged
- K&N cold air intake
- custom 2.5in magnaflow exhaust
- option b setup single pass
- cobra heat exchanger
- stock lsj heat exchanger

To come:
- clutch (mine is dying) ZZP or Exedy stage 2
- ZZP 3in downpipe

Then ill go to the dyno and test in on track..

 

ZzP stage 2 78lb valve springs spec stage 3 clutch 80lb injectors e85 377whp 377wtrq

 

2.4L Auto 2006
Soon to be Boosted

 

2007 2.4 manual
ZZP stage 2 air/liquid kit
At 7psi 233whp 222wtq
At 10psi unk
modified zzp stg2 air/air
At 10psi unk / still in progress.

 

When I'm done:

Boost/IC: M-62 3.0, dual pass, phenolic gasket, Opt. 'B'

Fueling: LSJ TB, Bosch 60#s, 91 octane

Intake/Head/Exhaust: Modified CAI->Euthanasia ported LE5 head w/ ZZP Cams, LNF Valves->ZZP Long Header w/Cat->GMPP Touring Exhaust

Internals: Wiseco 10:1 forged & coated slugs, ZZP Rods, ZZP Balance shaft neutrals

Drivetrain: ZZP 4t45e w/ 245mm 3000 stall TC and EP LSD, Pedders/FE5 suspension, Front Eibach sway Bar

MISC: Arp head studs, Ingalls stiffy mount, ZZP strut brace, Moog Front end, Timko front hubs

Almost there, tranny **** and sway bar left to buy and quite a bit listed yet to be installed.

Dyno in Winnipeg, 9 hours away and I'll likely make the trip this summer just to see my #s but alas no track anywhere close aside from terrace bay which has a yearly shindig at the airstrip.

 

I hit the track with my HHR at ~230whp and did 15.1@95 during the summer(I am a few hundred lbs heavier than the Cobalt).

I dynoed 257whp/233wtq on this setup:

Ported m62 3.1"(~9psi)
Ported LSJ TB
ZZP Cams/Springs
ZZP Phenolic spacer/Dual Pass/S3 H/E
CA Header
ZZP 3" downpipe
Magnaflow muffler
Stock flywheel/Exedy Stage 2

In the process of adding the following(engine is out):

ZZP 2.5" catback
JE 9.0 Forged pistons
ZZP Forged Rods
ZZP 2.4l Stage 2 clutch
Ported head
ARP studs
2.7" pulley
80s/e85

Looking to get ~ 350whp and 13 flat

 

No point in posting what I have/what is going in yet, but would love to see some slips and graphs.

 

2006 soon to be
zzp stage 2 air to air turbo,3inch catless downpipe,3 inch exhaust, le5 cams, 82lb springs, neutral balance shafts, turbo intake manifold, ls4 throttle body,100 octane tune maybe if not 93, maybe meth not sure yet,custom cold air intake,60's

hoping for around 300 to 320

do you think that 300-320 is possible with my setup that is what i am going for

 

06 2.4 auto

precision 5557s
log type manifold
rd fab intake mani
lsj tb<- gonna swap my stock tb back on for some theories me and vince are trying to workout
tial wastegate
zzp bov
hahn fmic
3in catless dp, with 3in pipe and 3in cherry bomb glasspack dumping to the ground before axleback(debating on what I wanna do)

1/4 mile best et- 14.3
1/4 mile best trap speed- 109
60ft avg of 2.6
the night I went I couldn't find my wheel lock key so I couldn't put my dr's on. Also couldn't lower tire pressure cuz I didn't have my air pump to air them back up.

 

Even with cams my power was falling off up top. Those were 2500rpm to 7200rpm pulls.

I am porting the head right now and have a 2.5" cat back on now. Really hoping those mods help bring the power way up.

 

why the change to air/air, just curious?

 

hhrfreak that torque curve is so sick, not even a curve just a straight line

 

i noticed that too, looks like it'll pull hard but smooth

 

main thing because i wanted a short ram intake
https://www.cobaltss.net/forums/2-4l...lorida-265764/

the second because the kit is design for auto, manual plus rotated mounts, aftercooler sits too tight in the engine bay.

the kit is awesome, but from the beginning i wanted air/air, because also is more simple. and you could say less weight? lol

 

i HAD..

50 trim turbo 2.4, 5 spd, exedy clutch, 10 psi, custom charge piping.. car weighed 3680 with me in it..

put down 247hp/267wtq on a stingy local mustang dyno.. (my goat made 299 and 303 on it) a 400/400 car with full bolt ons lol

ran best of 13.9 @ 109 at the track. no traction sucks. get some drag radials on these things.. if i can find another one ill do it again with zzp parts.





i miss it

 

5 spd with spec stg 3 clutch

stock lnf turbo manifold
bnr 2871
lk9 intake manifold
modified cti catback
zzp 82 lb valve springs
zzp rods
stock CR pistons from zzp (weisco i think)
turbo xs boost controller (shitty)
bdcustoms piping/ intake
hahn lnf catless dp
11-12 psi
60lb injectors
e85
dyno numbers. .... none unfortunately at the moment. I have to get to a dyno soon

car ran 14 flat on 9-10 psi with no e85 at 106-107 with shitty 2.4+ 60'



dont have any pictures since it was first put together lol I need to get some

 

Zduece... you weren't the only one upset to see your car die. Too few of us boosted LE5's man

 

257whp/233wtq

Not bad cant wait to get a header/downpipe
and a new clutch and see what i can do with a 2.9pulley



350whp that would be nice from sc only..
looking forward to see that..

what about cooling mods??

 

Hhrfreak... twincharge! GO!

 

Mine made 193whp with 0.0psi

Ran a 13.3 as a best.


LOL

 

Oh sorry forgot to list dual pass. Updated. I am running ZZP dual pass, phenolic spacer and S3 heat exchanger.

I was running a 2.9"(~10psi), but after I ported the SC I went from ~8psi to 9psi with a 3.1. I figured the gain would be even more with a smaller pulley. 100% meth has a thread on that in the LSJ section and he said the same thing. Smaller pulleys take a big advantage of the port work as he gained ~3psi on a 2.6 iirc and said the gains are smaller with the big pulleys since your not moving as much air. I hope the 2.7" will give me around 14-15psi. Decided to wait on pushing it since I was planning on building anyway.


Gawd! I wish...I am tapped out right now. Just spent a lot on the build.

I also just really like the SC. I love the whine, response and I think it has a cool factor. I also just want to know how much the m62 can make on the 2.4l. I haven't seen any over 300whp. Hopefully there will be a few supercharged 2.4ls rolling around @ 300+whp soon.

 

I should be in the 325-350 range I'm hoping. I have my TVS now, just buying the rest of the things I need and it'll be time to put it in. I can't wait, it's killing me.

 

Yes thats gonna be something keep us posted with pics and updates
