03 Cobra: How much is enough?

**PureVenom** · **03 Cobra: How much is enough?**

Ok, I am sitting here working on my plans for the car...as well as for the GT. Having to sell my throttle body sucks and is making me re-examine my goals for the car.

My car is not a track queen. It sees the track once, maybe twice, a year if it is lucky. I get a ton more joy out of get togethers and car show type events than I do racing it. I guess that would be why I was all about getting a vert over a coupe in the first place.

So...the point of this thread is this. I do have certain things I do want to do to the car. Some of them are going to have a definite effect on what type of gas I can run.

After hearing a whipple in person, while it looks a lot better than a kenne bell, it sucks ass in the whine department. So, it looks like it will be kenne bell or nothing.

Now, if I get lucky enough to find a 2.2L or 2.4L KB when I get ready to buy one...then I will be all over that. Nothing beats the 2.2L at WOT...nothing. The 2.6L isn't as loud, but is only a touch quieter.

I expect to run the stock 4" upper pulley with the 2.6L KB.....that will put me at about 19 psi. Now, I also plan to replace the stock block with an bored and stroked aluminum terminator block....with cams and headers. This should bring the boost down to about 17ish psi...but I don't think it will drop it enough to let me run 93 anymore. It will probably require 100 minimum...but it would be used as a nice weather driver/car show queen....so I might could live with that I guess.

Anyhow....if y'all had an 03 that you didn't take to the track all the time...where would you call it quits power wise? How much would be enough?

it will never be enough...........i guess the only answer would be the most power on pump gas, then call it quits

I can do that with a 2.2 or 2.4 KB...however, with my lower, once I put the 2.6 on there, my pump gas days will be over, even with the biggest upper pulley available....or else I have ot buy a smaller lower pulley.

Kyle · **Re: 03 Cobra: How much is enough?**

well since youre not making it a track car, i would call it quits after i've made as much power as possible on pump gas

A 600+ whp DD would be an awesome car to have. You should easily eclipse that with the mods your talking about. Why can't you run pump gas at 17psi.

for me, it would be as far as pump gas could take me, and is also compounded by the fact i live in cali, which while i like to say fuck you cali when it comes to how i mod my car, i still want a overall stockish engine bay, which is why i will probably call the cobra doneski after a ported eaton setup.

the guy i know has to run 100 octane on his KB 2.8H, even now that he swapped to the stock pulley he runs 100octane @15ish psi (the whole SpeedFreaks thing). hes limited to pumps that still serve 100 octane, i know 3 off the top of my head between Fresno and Sacramento, a 3 hour gap at freeway speeds.

once you cant run pump, kiss being a DD goodbye.

however if youre talking built motor and whatnot, why would you waste that setup by limiting yourself to pump?

for me, if im gonna build the motor, im gonna throw on the biggest blower i can find(3.4L Whipple or even better, Twins!), run the richest gas (Race Gas) and throw caution to the wind; im going all out.

i think having a built motor and then putting on only a 2.2L and pump is a waste. itd be like me building a 1000whp capable 4g63 and then putting a 50trim turbo on and tuning with pump gas. total waste of a 1000whp capable motor when i couldve done the above mods with a stock motor, just like a 2.2KB and pump can be done with a stock termi motor.

shit rambling........

When I last talked with James @ RWTD, we were discussing my thoughts on blower swaps. The 17 psi with the 2.6L will be about the same as 21-22 psi on the 2.2L KB or the whipple. Because of the larger size, and the improved displacement of bored/stroked and what not...I will be seeing 17 psi....but moving the same amount of air as 22 psi. That is where the balancing act comes in...

That is one argument I keep having with myself as well...I'm not against running 100-104 all the time...as once I hit this power level it will lose its role as a DD and become a garage/nice weather/car show queen. Actually...it is going to move into that role once I have it repainted to fix this shit paint job from ford.

I keep waffling...go all out, or call it enough when I hit X amount of power. I won't run the 3.4 though because it won't fit under the hood...or does it when you run smaller uppers...I don't know, I'll have to look again.

That's about what my first post was about too.

I'm just not sure when to call it enough...cause I am going to bore it and if I shoot for the stars, I'll run the 2.8L @ 23-25 psi...that will certainly end all debate of pump gas...and melt a good many sets of tires.

if you make a setup that has to run anything that can't run pump gas you are crazy you don't have another daily driver. if you do thats another story all together

Why don't you just run 13 or 15 PSI as your DD and maybe up the boost when you go to the track?

Because if I go kenne bell, I can't get a big enough upper pulley to get down that low...the lowest I can go is 20.5 psi....unless I swap out my 6# lower...

**SpectorV** · **Re: 03 Cobra: How much is enough?**

My take on it is having much more than I currently have would be usless as I really cant go riding that much due to traffic. I enjoy keeping it nice and going to shows more than racing which I wont do on the street. I dont like breaking things at the track so I wont go there either. That basically means I want a bit more power and to modify it to make it look better and do good at shows~ and get togethers.

No need to do things that wont get you anywhere.

unless you get an older kenne bell 2.2, they are not going to be as loud as the eaton either... Can't say that I've been impressed with the numbers i've seen out of the kenne belle 2.6's though, seems like most are making about the same as the smaller whipple. I say go big or go home!! Get the 2.8H!!!

lowflyn · **Re: 03 Cobra: How much is enough?**

To me, when you can't run pump gas you have gone too far unless you are building a race-only car. I don't plan on pushing mine past the pump gas point. I'm thinking ported/pulley will be about it on the engine, then I'll concentrate on the suspension.

Says the man with the whisper quiet whipple.
