if you read a few posts back i already stated, i'm not implying anyone else on this site. but i must say if he is the only person with a cobalt to do the basic i/h/e and cam bolt on's that's pretty sad lol. i'm referring to other l61 owners yes but not cobalt owners. most of them are cavalier owners, although obviously the l61 came in a variety of different cars. saturn's, grand am's etc. etc. ecotecforum.com is a good place to see some of these car's. or j-body.org

 

yes?

 

when i was supercharged i dynoed at 197whp on 12psi. I just find it hard to believe with really little work he can be hitting that kind of number on a N/A car. not trying to stir the pot but ive got to agree with the rest of the guys.

 

well you gotta factor in that just cause its the same engine doesnt mean it made the same power in the years/model cars they were in. the L61 ranged between 140hp and 149hp and tq ranged between 145tp and 155tq..

 

ill be impressed if he actually did hit 200hp NA. but, lets see some track times instead. thats all that matters in all honesty

 

i dunno. i see where everyone is coming from, im just tryin to bring out every single reasoning possibility i can think of lol

true dat!

 

you should've been higher then 200 whp with 12 psi .. you should'vee been around 220 maybe a tad more

 

Bwaaahahahahahaha!!! Hell yeah!

 

similar mods as tom, yes im one of the closest

here some data on mustang dyno.
way difference number
but faster on the track since a year

-no head shaved
-stock lsj manifold
-lsj downpipe with hiflow cat
-2ź custom catback WO resonator
-flywheel
-everything else is similar to tom

i challenge him to dynoon a mustang dyno

this is a CAMMED DYNO sheet and it video

was this pre cams or after?

 

i got some very nice time according to my similar setup. the huge difference between him and I, it is the WR and my drag radial. ijust put my cash where i need to. i need tracion i bouht drag radial. i need to be lighter just take a hours and bang you are mid high 14s'

true, but most of those power changes were the result of varying intake manifolds and exhaust manifolds, and these parts are getting replaced in the NA builds anyway. bolt-ons, aside, the only difference between these early L61's and the cobalt's '07 L61 is the latest of them had a sliiightly different cam profile, but again, the cams are getting replaced in NA builds as well, so thats also irrelevant

 

mid to high 14's ?!?! you guys are ******* nuts. what a waste of money lol

 

lol this is so redic this is when I realized i have a econo car and lookin to buy a integra as my toy. At least mods are cheap and they become quick:O) Its so much cheaper to be a ricer

 

more ricers here then on honda-tech lol.

go into the drag racing section and people do work. here its about headlights and exhaust. im just here for the lolz anymore....like this thread

 

ahh got ya...well tom, im out of ideas lol. dont know how to defend your case..good thing im not a lawyer lol

 

that it is your opinion

i m happy with my setup because

- roll as often as i can and i win almost everytime in my categorie (4 cyl NA)
-still got 6L/100km
-unique setup as tom
-low cost for the fun i get
-on źmile, I make so fun against 4cyl NA and boosted and 6-8 cyl.


according to my calculator
i got 178hp (weigh+ traping speed + ET)

wih a 1200kg, i need to trap 97,78 mph or 13,77
i tell u, it is gonna be impossible for me

6 MPH is a huge steep

 

i know your from canadia, but i cant understand half of what you said.

you win almost everything when it comes to 4 cyl NA? lol, wut?

if your running 14's your not having fun against most v6's let alone v8's.

 

:n ono:

poor you i from quebec. it is way different that canada. hahahaha french

hahahaha you are not the only one that dont understan my writing. but you know what, i really dont care about that because you dont write and read in french. I do write a bit in english. i do my best BTW.

if you argu about my english writingit is because you run out of argu

yes my only defeat are against rsx type S, civic 06+ and type R

on the track i need more than 4 cyl NA to give me hard time.

 

True. It's very possible this dyno that gave 180WHP reading would take a stock 2.2 and measure 150WHP.

Another way to compare 2 setups is by monitoring MAF readings. Pretty easy to tell what kind of gains you made by doing this. In this entire thread, I haven't seen any technical detail of why the engine would make 200 or what special things have been done. This leads me to believe that a non-technical build has been done because an engineer would be posting up data from many different areas to support claims.

Adding a SC at 12psi, you're sure to see the MAF climb ~80%. I would like to see the NA MAF numbers on this car.

 

i dont understand. what do you mean you need more then a NA4cyl. to beat you?

theres tonssss of other 4 bangers that will destroy our cobalts lol


( and i dont need to read and write in french, Im American thanks for your effort though)

 

maf readings are a good way to monitor changes.. however you as well as i know that you can skew maf lbs/min readings

 

yes.
my saturn is on a big diet. during summer it weight under 1150KG. it is wingless.
i dont remember the time i get a defeat againts a 4cyl NA. lol
S2000, type S, SI 06 and civic swap type R and those who give really hard time.
but cobalt 2,2 manuel and fully mods are not bad at all.
in this video i got more top end. i m a cam lover. i evaluate around 10 whp my gain with cam.

as stated...no i wont do mult dynos, part because of cost, part because i have no prior dynos anywhere else and ive dynoed on this one mult times.
This dyno showed 145 with intake and header, dp, exhaust.
showed 156 with the same and tuned
and then 180 with current mods (exhaust crap designed header/dp and a bad tune)

so honestly...that pretty close for 125 stock would show.
I have no way to get to a dyno that "more stock ls balts dynod at" its just not that easy out here

as for huckers dyno...he dynod on a mustang dyno, AND just as easy is it for a dyno to be happy...it can be calibrated and show less...what we all need to come to an understanding on is that a dyno is reaaaaally only good for comparing changes on the same car from run to run, tune to tune, and mod to mod...becuase EVERY dyno is calibrated differently and different types of dynos will read differently...that doesnt make any of them necc right or wrong, just different from one another. Just because you may dyno on a crap calibrated dyno (we can call them sad dynos if you want lol) doesnt mean everyone elses is wrong. Dynos are meant to show advantages and disadvantages within the same car for different setups, to give you a tool to let you know you are headed in the right direction...

If i dyno and show 200whp on the dyno I have been using for years (and also btw is Vinces from trifecta 's preferred dyno to work off of (he is local)...so that is enough for me) then as far as I am concerned (and really...rightfully so) I have a 200whp n/a cobalt (and the dyno list here on css will comfirm this too...).

Now, if you want to paypal me the money for another dyno, or drive out here and we can run on one in the same day...then go for it. otherwise, I have the numbers to back up what I have done so far, and its within reason to see and say that I will see 200 without any if not much more modification.

and to zoomer, unless your going to pay for a shop to build my engine, or do it yourself, then STFU. of course im not an engineer...im a back yard mechanic like 99% of the people on here and pride myself in the fact that I build my own ****, that it runs fairly reliably, and that I get good results out of it.


And for track times? without taking ANTYING out of the interior, runnin on normal street tires, and **** launch (jsut finsihed rebuilding and was afraid to break it ) I got a 2.6 (i think) 60' and ran a 14.951 @ 95mph with this car...
like I said...dogged off the line...
if i stripped it down in weight like huck and gave him the keys for a pass on the track, I would be VERY surprised to NOT see VERY low 14 sec passes.

Also, when hucker listed his mods, look closely at the exhaust setup and still have stock compression...those may not look like alot, but they can make or break a build
this could be a leading cause of why the numbers (along with being on a mustang dyno) were not up to the ballpark I am running in.

 

Tom what kind of flow are you getting across the MAF? (lbs/min) Zoomer is 100% correct that MAF flow is a very good way of comparing setups.
