What do you guys think

**earleymp** · 10-26-2012, 07:34 PM

Okay so i've decided to keep my car.. (for now at least lol) so wanted to get some ideas thrown around about what to do next to my car, performance wise. I want it to still be street legal and everything but just insane on the track. It's pushing, if not, reallllyyyy close to 500 rwhp as we speak. I was thinking some good msd coil packs and upgrade the fuel system: like msd fuel pump booster and fuel rail (everything else when it comes to my fuel system is stock except for #60 injectors, so i think that would help a lot) would be a good start.. And i know a lot of you probably don't know really anything done to it, except for Cam, so i can list everything and go from there too. Also, the last 1/4 mile was 11.8 at 118 but that was awhile ago with a ****ed up clutch, so of course one of my goals is to hit the low 11's at least..

Thanks

The easiest way to get there would be to put a different supercharger on it. If you've already got 60# injectors then the only other supporting mod you'd need would be a kenne bell boost-a-pump if there's not already one on the car. You don't need coils or fuel rails.

There are some who've taken full weight cobras at 500RWHP to low 11's but it ain't easy and would likely take quite a few passes at the track to chip away at your et's. It would be a lot easier to do with an aftermarket supercharger and you might even get high tens. If you hop on svtperformance you can find a used kenne bell or whipple supercharger for around $2000-$2500. You shouldn't need any other upgrades besides that and the boost-a-pump if you don't already have one.

+1 on this.

Your prob looking for the KB 2.4 or the Whipple 2.3 to get you where you need to be and be efficient at the same time. Theres very few KB 2.2's still out there forsale. They sure do sound awesome though!

Handiling and breaking mods...

**scott5** · 10-27-2012, 12:23 PM

SRA swap
Buy a ported eaton with a killer chiller or go twin screw depending on how much boost you wanna run.
big and littles
Good clutch

That will get you where you want to be and be reliable.

You can keep the irs but if you wanna be "insane" at the track you will break it alot. Yes there are guys who run 9/10s that run IRS but those guys also break their IRS ALOT. So SRA will be a more logical and cheaper choice in the long run.

be different man. big procharger or vortech ftw

**Cam99** · 10-27-2012, 01:21 PM

It already has a posi ported eaton. I actually don't remember if it got a bap at the same time all the other mods got done. twin screw is the easiest way to get more hp out of it. I was either going 2.2 KB or the ported route that I ended up going, because I wanted that old school cobra scream from it

EDIT: It has a new clutch in it also now

Braking mods would be less frustrating

I would do Killer chiller then. Esp if your going to stay around 15psi.. If low 11s is all you want. I really dont think a twin screw is needed. If you can drive and you have the hook. A ported eaton will get you there. ttk53 is in the 10s with his eaton at prp.

Lighting it up will also help too, not necessarily removing parts but putting lighter ones on. k-member, a-arms and so on and so forth

He would have alot more money in that and in that case you might as well go turbo!

**Cam99** · 10-27-2012, 01:52 PM

Turbo would be sweet. Checked my old threads. It did have a BAP put in with the porting and it has a sct MAS so it's ready for whatever aftermarket power adder you want to throw at it.

true but, the morld is full of twin screw cobras with irs runnin 11 seconds. i just like to be different

**Sonic03snake** · 10-27-2012, 11:10 PM

Stick with the stock coil packs, ive been out of the cobra loop for a while but they were junk a few years ago.

I agree with this. I tried two sets of msd's on my cobra and they both would just break up high in the revs. Stockers will do just fine.

ive went low 11.20s@124 with just a upper pulley and offroad exhaust,cai and no tune on a 03 cobra made 445rwhp and car was @ full weight

**Stroked03Cobra** · 10-28-2012, 09:59 AM

If your looking to do the killer chiller, id just go with the KB liquid cooled 2.4 and be done. I do like "different" as Rich stated, I looked into the F1A Procharger kit and decided turbo is the way to go for my application. Its your car, do what you want with it. If budget is an issue, go twin screw, ull be happy!

This is what you need to decide on.

**wickedsnake03** · 10-28-2012, 05:01 PM

2 biggest factors are budget and plans for the car.

If you like driving your car a fair amount on the street, and only plan on it being at the track a few times and not maybe seeing the best times it could I would just get a set of track wheels for it and spray it. Ported eaton spray cars fly.

Twin screw blowers are a ton of fun on the street as they build boost really fast, But with that comes heat. And the dreaded heat soak, If you spin a twin screw with any real kind of boost you are gonna heat soak. Again plans for the car would dictate blower size, But I will say one thing. Bigger isnt always better. I see alot of big blower cars struggle cause they run low boost and arent even in the blowers efficeny range. I would say either pick up a used 2.3 whipple. Or if it was me I would go with the new tvs 2.3, they are makin great numbers on pump gas and tq numbers are always showing higher then the whipple 2.3

If you plan to race the car alot, Or want to just go all out at the track when you do take it then a solid rear is nice, But with that you start getting into big and littles, spools, and either c-clip eliminators or 9inch ford ends. Which if you go with 9inch ends you cant retain an ebrake. which is nice having with a stick car.

From what im getting your lookin for a fun car, that when it does make it to the track can go 10s. With that said do it cheap and spray it. Ported spray cars can easily run with twin screw cars.

Or spend some cash and buy a twin screw. And always have the power there. again used 2.3 whipples are everywhere. And the tvs 2.3 is really comming on strong right now.

Boost makes heat, be it a eaton at say 16# or a twin screw at say 20#. When you start spinning them you will have heat, and if your lookin for the max all the time performance you gotta deal with that heat. if you aint to concerned with losing a few mph in summer heat then its not an issue. I have a 2.4kb and she heat soaks fast and bad in the summer. Lou can atleast also to heat, He told me first hand the amount of ice he used to go through while racing a whole weekend.

**earleymp** · 10-29-2012, 03:28 AM

THanks everyone, as cam said it has a good clutch and ported eaton. Also I meant everything besides a twin screw. I'm happy with the ported eaton now because it sounds just as good or better than a whipple or ford racing twin screw plus I've been researching, also some guys on here are getting into the 10's with a ported eaton. So since I don't want to deal with that hassle and shell out $3k just for the s/c when im already getting up there on money into this car.. any other ideas of some mods besides this and the coil packs?
