I was told that they are Molly pistons and while they are good quality they do have the obvious signs of the casting process which is the reason we need to go forged. Molly would likely be a better place to get more accurate #'s instead of JBP giving a professional guess. I can ask the next time I call them, likely the end of next week if you want or can't get an answer from Molly Pistons.


You need to give a little more info such as how much power do you want to run and what are you planning on doing with it to say what you all need to upgrade.
As for the twincharge system we won't have a final price on that until an unnamed company finishes the system and we have tested it on my engine. (No I won't say who it is but I will say that it is not Hahn Racecraft)





Yes Mev told me about the changes when I spoke to him today. The Eibach sportlines were ordered over a month ago and today I discovered that Eibach has no stock and is not making anymore for a few weeks yet. So after you told me about the coil overs I have been thinking about changing so I simply canceled the sportlines (lost sale Eibach) and told Mev to give me the steel body coil overs. So in away it's your fault so you should have to pay something to help so my wife doesn't kill me when she finds out about this little extra.

 

Sounds like a great build up Victory!

One question though. Did anyone take a look into the (FGP) F35 Transaxle? Would it be able to handle that much power? I'm assuming it's going to be built?

 

I am getting custom transaxels from The DriveShaft Shop. I had to send in my hubs to have the spline size increased a bit to be able to hold stronger halfshafts. These will be stronger than the 400hp version they offer as these will be good for 600whp while running slicks.
Also I talked to TTR and they said the F35 would hold up to 700hp but only if it has the Quaife LSD.

 

Ah thats good to know! When I had my SS/SC that was one thing I had a hard time finding out...what the limits for the F35 were in stock form. Did they say by chance how much it could handle in Non-LSD trim?

 

Sorry I didn't think to ask at the time.

 

Wow! Seems to me that you could BUY a vette for the same cost as the stuff your doing to this car... I LOVE IT

 

lol I could vary much say the same thing about you, your build is what inspiered me to beef up my valve train and made me decided to bump up my rev limiter. I'm pretty much building my own monster SS/SC just a little slower then you are.

so we'll call it even

damn it's never cheap to do things the right way

 

i swear the more i read about this build, the more i want to do the same as you. only thing stopping me is $$$.

 

if i had coin id do the same thing looks like a 12 second ss by next year will have to do lol

 

I am not planning on doing the body and to be honest I am too cheap to spend money on looks. I am going to look into getting some carbon fiber parts but painted to match the car. The one mod that has been suggested that I am looking into is a customised c\f hood with heat extractors built in. And maybe an awesome paint job, Victroy Red with lots of clear, to replace the crappy factory paint.
As for walking the Cobra's and Vette's, the Cobra I want to hunt down has the name "Shelby" and I also want to add the Viper to my to do list.

 

unting for vettes and Vipers lol gotta love it.

just try not to use slicks and drag radials as a daily driver, or you'll quickly learn how expensive changing your tires once a month can be.

it will make paying for all those mods look like lunch money

 

 

Can you picture the look on their faces when a Cobalt blows them away? (at least some of them) Now, I won't be street racing because with my driving record they will throw the book at me and maybe crush my car. But I will drive aggressively enough that these fellas and their cars will want to meet at the track to see how this car really goes.
And I plan on getting two sets of tires for the drag strip and another for thes street so I always have backups.

 

Yes it must be a waste of cash. That's why VW is starting to do it on stock engines.

I swear the concept of twincharging brings out the haters moreso than almost any other car topic. Peope will never grasp that just because you can get the same or better peak numbers with a SC or TC alone, doesn't mean you'll make the same ammount of power. Area under the curve is huge, that's why people were so jealous of the torque curve on the LSJ when it came out, 200 ft/lbs at such low RPM levels,,, Honda owners everywhere cried when they saw that. You'll be making insane ammounts of power and torque ALL throughout the RPM range. SC or TC alone will always come up short in this aspect

I say best of luck with it man. I can't wait to see how it turns out.

 

^^ 100% agreed^^
this is what I've been saying since I first herd about it two or three years ago.
I just stopped arguing with people, cause in the end they throw the it's to complicated, or to expensive agrument on the table.

all I can say to that is you have to pay to play, and to play with the big boy you really have to pay

 

Victory Red!... Say I have 5k to spend... I'm not looking for as much hp as you're going for but I want to be faster than these guys running 2.5" pulleys. Low 12's. I'm tired of sitting in srt-4s and evo's and feeling how much those things really pull. I'm really considering twincharging mine. Would 5k be enough to safely twincharge it while not risking any of the the other parts going to **** w/ out the need of upgrading them as well?

 

^^^I will go out on a limb here and say for sure, with the following stipulations

1) Internals, if you wanna break 300hp safely you will need pistons, depending on your abilities/who you know this installation could be very costly.

2) Again depending on your mechanical abilities and know how, you could save money tackling this project yourself, but I would expect kits themselves to be well over 3k, when they first come out.

So in capable hands 5k could certainly twincharge your ride.

If you would rather just hand cash to a person/company and have them do everything for you, a project like this could easily go over th 5k mark.

If I were you I'd wait until Hahn, and victories mystery company release their kits. We might all be pleasantly surprised at the pricing. Even if not it will give some insight into possible set-ups / solutions to issues you would encounter buiding your own.

Hope that answered the Q

 

I just got back from a saab dealer so I could see the parts on a 2.0L Turbo and man all I can say it will be super easy to utilize these parts. bolt it on and put it through the SC. and I am all for it and on the same page. going all turbo is not easy either.

Everyone has an opinion. I have to say is this. we shall see. and I am willing to put money down on the success of this project.

EDIT - you know I am so happy about it. I can build my engine, boost it with the supercharger then get the it twin charged a little later and tune it again and go. Just awsome.

 

I would agree with all of the quote above. My advice would be do the pistons now because you don't want one of those to fail and you screw up the engine. Once mine engine is in there should be a couple of choices of twincharged setups to choose from and there will be pricing choices.
I would also recommend again that people error on the side of caution when going for the power. It will cost more if something breaks and having to fix everything than just putting the parts in to begin with.
There are parts that can be changed to make the most of everything (which is what I am doing) but many people aren't going this route.
Pistons, pistons, pistons. Imagine one of them failing at 7,000rpm. Now you pay for a brand new block. Cheaper to change the pistons now. The rods are fine. They can be improved upon for higher reving engines (I am going to 8,000rpm) but for most guys they are just great.
One thing to consider is how much boost the turbo will be adding. Because of the extra boost I am having ARP head studs installed as well as the ARP studs to replace the main bolts.
So depending on how much power you are going for it can be as simple as pistons and a turbo system or as expensive as a new car.

 

I will be waiting for Hahns to come out. I'd say I am a little more than average w/ my knowledge on cars. (More of a computer kind of guy) I would be doing the "Give a company 5k and have them do it all" route. I would love to just drop the car off somewhere and let them have it for how long it takes (when the hahns kit comes out) and have them install everything that I need. Hopefully 5k isn't out of reach. I'll have the money in December and I have a winter car to drive so I would be more than happy to drop it off somewhere and have the company work on it.

 

The good thing is that if you are doing this in December you will have more options and results to base your decisions on.

 

Yeah I thinking pistons with stage 2 should net over 300 HP

 

Using VW as an example is not the same in this application. VW did not build that car for the purpose of making huge power and for people to race. Is this setup a waste of money??....possibly...know one really knows....no one has got a twin setup on their car running. If someone can get this to work..it'll be awesome and I wish victory red the best. I can grasp the power to be made with this system and does sound good and looks good on paper....but it is complicated and will cost alot of money. Tuning is obviously gonna to be the biggest issue...it already is for all cobalt owners, but now we're talking about trying to tune two FI systems on one car.

 

A twin screw S/C has the benefits of low end torque with the capability of high boost level. It also creates half the heat of a roots style and takes less power to turn than a roots.

I'm not going to argue over it. I'm just stating my thoughts on the issue. It's similar to the hp vs. tq debate. you can argue until you are blue in the face, but neither side is 100% right.

 

do pistons alone on a car would be capable of how big of a gain? 30whp?
