500-550hp 97 Cobra?

[Night/MareCobra]

all I finally got my goal figured up for spring time and I'm really shooting for 500-550hp my plans:

-manly 03 04 Cobra pistons and rods with stock crank
-all ARP bolts
-Melling oil pump
-stage lll blower cams
-60lb injectors
-Anderson power pipe
-more boost from the vortech

That's all i can think of at the moment I'm sure there's more but any thoughts or things i might have left out to get to my goal would be appreciated. Thanks

That should get you at 500+ no problem. What's the fuel setup, other than the injectors?

[Night/MareCobra]

Well that's one of the things i needed help with I'm not sure what I'll need i have stock Cobra fuel system

[BuckeyeAlex]

It depends on how far you push it I guess, but a BAP should get you by at around 500-525 whp. If you plan on pushing for the higher end of your goal, I'd at least upgrade the pumps as well. Mine has a Fore triple hat, return setup, Fore rails, and 80 lb injectors, but I'm on E85 with spray. On blower though I'm running a similar setup to what you have planned, other than the Vortech (Posi race port) and make 570/525.

[Night/MareCobra]

That'd be nice I'll see how far my budget goes i wanted to do the e85 to. And I've never had a supercharged car before so I'm kinda lost a little bit but the kit i got came with some kind of vacuum booster is that the bap

[Night/MareCobra]

Its a FMU...does that help anything.

[BuckeyeAlex]

I'm not real familiar with the Vortech FMU setup, but I'd say it's more for a fairly stock motor with a Vortech on it, so with your hp goals you'll probably still want to upgrade the pumps or wire up a boost a pump. The boost a pump just wires into your fuel pump driver module in the trunk and allows the pumps to flow better at the same duty cycle.

[cstreu1026]

The FMU is a bandaid at best. With the right meter and injectors along with a tune there is no reason to have it on the car. The boost a pump ups the voltage to the fuel pump to increase flow. I would just install a bigger in-tank pump. Being a 97 makes it easier since there are more options for pumps. I think there are some direct replacements that flow 300+ LPH that should be more than adequate. Combine that with a set of 60# or 80# (for E85) injectors and a good MAF and you should be all set after a tune.

[Night/MareCobra]

Thanks i was really curious about the fuel setup for that so that helps alot

[Walter]

Yup, skip the FMU and BAP.

This should not be hard too make 500 with what you are doing just upgrade the fuel system and have fun with it.I cant wait to see what my car makes!If you decide go to E85 check and make sure you can get it around your area.

[Night/MareCobra]

That's the only bad part the closest place to get e85 is about 20-30 min away

[BuckeyeAlex]

I have to drive about 30 min to get mine and honestly, I don't think it's worth it. It has it's obvious benefits, but to me I'd rather be able to jump in the car and drive it anywhere knowing I'll be able to get fuel everywhere. Right now I have to plan out when I'm able to drive the car, how much E85 I have in the garage, and ration it out. Just takes a lot of fun out of it. It doesn't necessarily stop me from driving it, but I'd sure as hell drive it a LOT more if it was available closer to me.

[cstreu1026]

that's why mine is on pump gas with 11.5:1 compression. If I didn't have to drive 20 miles each way to get E85 it would have been more like 13:1.

Im not sure how different the 97 Cobra fuel system is from a 03-04 Cobra but here's some info on fuel setups at different hp levels from SVTP. Hopefully this helps.

Good info!

I had this fuel system on my 1997 and I liked it. It is up-gradable if you decide you need more. It supported my 600 rwhp with plenty of room for more. My car had a novi2k pushing 15lbs on pump with meth injection.

They are very different. The 99+ up car have a returnless system and the pre-99 cars do have a return line and operate at generally lower pressures.

You can get there easily with stock cams. Also, getting away from the 8.5:1 compression 03/04 pistons will go far in increasing hp and tq, go with a minumum of 9.5:1.

The stock fuel rails and lines will easily support the power you want to make and a 340lph pump may be able to feed it. Lethal Performance sells them and can tell you if one will work on your combo.

[Night/MareCobra]

On lethal performance they have the pistons on there with 11cc dish and 18cc dish which one should i get for what I'm doing

[cstreu1026]

Assuming its a .020" over stock stroke engine with minimal machining of the deck I came up with 9.15:1 with the 11cc pistons and 8.42:1 with the 18cc. To get to 9.5:1 you will need a piston with an 8cc dish.

11cc will give you a 9:1CR with the stock combustion chamber volume while the 18cc pistons will be at 8.3:1. If you cut your heads .020" the CR with the 11cc pistons will be right where I recommend.

[Night/MareCobra]

Oh ok so should i get the stock bore pistons and just have the cylinder walls cleaned up or should i go ahead and have the block honed out to .20 over with the 11cc dish? Also the vortech kit i bought was without injectors coolant crossover and crank pulley so does anyone know where i could get the coolant crossover and the crank pulley

[na svt]

Bore .020" that way you'll ensure the correct piston clearances. Like I said, the 11cc pistons will work buried would mill the heads to bump the CR to around 9.5:1.

The supercharger is driven by the stock damper, I'll give you if you don't already have one.

[Night/MareCobra]

Ok I'm kinda new to all this so its alot of help and i got a march damper on mine

You'll need a stock damper then.

Oh ok...and will my transmission hold that much i got the tremec t45 out of a 99 cobra
