my car is at like 260 and i'm not heavily modified......IMO heavy modding is 2.5, 60's, hptuned, pistons, rods....... n20....

 

It doesnt matter what kind of dyno it is, mustang/dynojet whatever.
a dyno means nothing unless theres a baseline, or a relative comparison.

But since we cant seem to avoid the comparison to the ss/sc, instead of just congratulating him on how hes doing....

Unless you dyno a S2 with boltons ss/sc on the same dyno, on the same day....its just guessing.
How do you know that ss/sc with boltons wouldnt dyno 245 on that particular dyno?
you dont. every dyno is different.

Like i said earlier. take her to the track and put the facts up on the board

 

yeah track should be next week, so we will see. for comparisons sake though, this setup should at least be good for a 13.7, whats a regular stage 2 run?

 

After you've seen 2394892301482391048 different cars dyno on different dynos and spent countless amounts of time comparing them all, it's fairly easy to predict differences. Mustang Dynos and Dynojets are also very consistant dyno to dyno and compare to each other very consistantly. Weather differences are also a no brainer and easy to guesstimate (even after the correction factor).

No need to be sad that a 2.4 with a very low boost turbo kit is making better numbers than most SS/SC's.

 

Ouch, Someone's gonna get pissed about that one.
Keep in mind that this is on a conservative 8 lbs of boost, and the LE5 motors have been proven up to 400 HP on stock internals.
Some minor adjustments, increasing the boost, and I can see Hahn's kit easily slamming down 300 HP with 325 ft/lbs or torque while still being safe for the engine. We all knew that the 2.4l engine "technically" had the capability to have the biggest numbers, why is eveyone so quick to cut down on the turbo kit?
I think some healthy competition is only going to make some of you LSJ guys find new ways to push your engines to the limits, so it's good for you too

 

Yeah in the fall im gonna shoot alot higher for the numbers I need, up to 10-11 psi and maybe be around 270whp or so. I just wanna do this is stages to see how the car reacts and takes to being boosted.

 

They can grow up or shut up.

The "I hate anyone faster than me" insecurity of this community is rediculous. I hope it offends the SS/SC guys, the majority of them need to grow up and lose the ignorant fanboi attitudes. The 2.4 guy is faster, boo fricken hoo. Why can't you just be happy for him and whole section of the community?

 

sure the motor can take it, but what about the cute transmission? i forsee it puking in the future.

 

highly doubtful, hahn wouldnt even put their kit out in auto form for the cavalier due to the weak auto tranny. the fact that they released this kit mainly for the autos has my trust that they know this tranny is strong, we already know this tranny is stronger than the ss/sc's 5 speed...

 

Good job man,im glad you got it running good.

 

thanks man

 

you're putting faith in a company who made a tranny that can't handle the stock power.

for reference please check the 4l80e, 4l60e, 4t65e-hd <----this one is crap.

gm doesn't have the strongest auto trannies in the world, for you sake, i would get a shift kit to help it live a little bit longer then 3 months.

im not trying to **** in your cheerio's, just saying its going to happen.

 

what are you talking about? i never said hahn made any tranny... it has a "shift kit" its just all done electronically with hp tuners so its fine. it also has a tranny cooler.

 

im talking about the GM TRANSMISSION. did you fail to read this part?
i guess you skipped this part

 

who **** in your lunchbox?....the trans can handle the power...and is stronger than an ss/sc trans....hahns proven it with thousands of miles of rd.....so unless he puts 10000 on the car in three months then i dont forsee any tranny failures

 

::sigh::
nevermind.

 

This is a good point of debate. Allow me to chime in...

As mentioned by celicacobalt, we have not offered our Cavalier-Sunfire system to automatic transmission customers. There are essentially two reasons for this:

1. Our testing indicated the Cavalier/Sunfire automatics would need software upgrades to enable shift characteristics suitable for the additional torque, and such software access was not available at that time. We intentionally drove our own transmissions to destruction to detemine this need.
2. The system we designed for the Cavalier/Sunfire would not physically fit the automatic version for this reason.

These systems were designed and brought to market in 2002/2003. However, a new development occurred last year: software to accomodate the needed shift behaviors became available!

Now, let's consider Cobalt and our current turbosystem offering:

The advent of software enabled us to develop an effective automatic transmission turbosystem for Cobalt. Additionally, the Cobalt version of the 4T45 is the most refined version yet, and boasts numerous upgrades as compared to the Cavalier/Sunfire predecessor.

But that on its own was not enough...I insisted that we have build two complete prototype cars (a 2006 and a 2007), at considerable expense, to prove out the concept. Total field testing time to date from both prototype cars approaches 10 months, encompassing thousands of road miles, dozens of dyno pulls, and drag strip testing.

During this time, we have carefully assessed and refined the transmission's behavior, and I am pleased with the results. Is this a guarantee of zero problems forever? Certainly not. But after considerable development and testing, I am confident that no problems exist at this time.

The suggestion in an above post of a 'shift kit', while good intentioned, does not address the essential need. There is no 'shift kit' for these electronically controlled transmissions...these objectives are achieved through reprogramming shift characteristics.

Now, we are big fans of the manual transmissions in these cars...we've personally subjected them to more power than anyone! And we aren't done with that...our Sunfire project is hitting the track with 750HP through a Getrag 5-speed transaxle this year, and will tell much of what's possible there at mega-power. Previously, we've put 150 passes on this car at 11 and 12 second power levels with no trans issues.

But our thorough development of this automatic transmission has been successful, and we know that we've now begun a new journey. At this power level, so far, so good. Will it take more? By the book, its rated at more torque than the 5-speed, and we can see what the 5-speed has achieved! Time will tell, and performance enthusiasts who aren't afraid to push the envelope will find out.

We've set the foundation, and shown it can be done. Let's see where it goes!

 

Thats awesome man. What a torque monster!



Hahn Racecraft owns. I want the s/c turbo swap right now!

 

to area47^.....i believe that pretty much says what i was telling you....so theres the information....think what you will of it...

 

Very nice numbers man. That car has to be a blast to drive.

 

it is, scary sometimes how much power i have and I have to take it easy as i am still getting used to loads of torque. just ordered new tires since my fronts are almost at their limit and I hope to hit the track next week if the tires get here soon enough.

NGK Iridium LTR6IX-11

I have these 1 step colder plugs installed and I was wondering, is it normal for colder plugs to take more cranks to cold start the car? I doesnt start up as easy anymore is all but runs great. These are gapped at 0.35 by the way. Tuner said he couldnt change the gap on them from stock anyway since they are supposedly so fragile.

 

vroom vroom, whoosh. Im getting to love these sounds lol

 

What's your 0-60 do you think?

 

sweet ass man, im lookin forward to getting this kit in the near future.

 

We've tested this on our prototype, and it's in the low 6-second range.
