Took an 08 SRT10 for a ride

[agentf1]

WOW, nice car. Now I want one. I think a nice SRT10 vert would look great in my garage next to the GTS. I was impressed with its power but think I would probably eventually get bored with that withing a week of ownership which brings me to the following question...

How much HP is enough? I know it is kinda like money where you can never have enough but where does it end. Not to take anything away from the car as it was awesome and for the prices they are going for now it is like a soft dick, you can't beat it. I also drove my buddies 03 Cobra that has close to 700rwhp and it is a LOT of fun on the highway but it is unusable in first and second. I do think the Viper is a better platform and can probably put it to the ground better than a Cobra can so I am guessing close to 700rwhp is probably pretty close to a perfect combo as far as drivability etc etc.. So my Q is what is needed to get an 08 SRT10 up to 700rwhp. I am sure FI will put you way above that. Can it be done with bolt ons?

Anyway, I see a 08 or 09 SRT10 in my future. I really like the coupes better but it would be nice to have a vert for those nice sunny days.

I guess this is enough rambling for one post.

bolt on's won't get near 700rwhp without forced induction

you might see 600rwhp with bolt on's if you did enough and had a great tune

The money it would cost to get 700rwhp all motor makes supercharging or turbos the way to go.

800rwhp is lots of fun if you run a quaife diff and is enough to keep you from being bored. After 1000rwhp it's pretty much white knuckle stuff on the street.

I'd go for an 800hp TT set up on pump gas with more on C16 for when you want to track it. If the 08 diff is anything like the older models you will def want a quaife diff - the difference in driveability under loss of traction (safety factor) is enormous.

Sounds like he should buy mine.

Look in the for sale section.

2005 UGR TT Convertible. 3800 miles. Still has 2 years 24,000 mile warranty from UGR. And it will be cheaper then an 08 or 09 to get the horsepower you want.

For "me", I have found that around 600rwhp is perfect for a mostly dedicated street car on street tires. My old turbo car had a built auto, so it was still a bit of a white knuckle situation if you pushed the go peddle while cruising at slower speeds and it down-shifted. However, with that same power in my N/A GTS, it allows me to pretty much stab it in any gear and go. First gear can still be a handful when it hits max torque or in cooler weather, but I know the car well and use my right foot for traction control:D

I also think the optimal hp level will vary based on the build. I would think since the power characteristics of a N/A or Roe car are different than a Paxton car, for example, I would want more power if it was a Paxton car.

I'd say 650-700 RWHP are within reach with bolt ons/head work. Hennessey got 616 RWHP with just headers/exhaust. Now the new tunes are adding some more power to get you closer to 640-650 RWHP. Send your heads off to Greg and I think you may get a lot closer to 700 than most would think possible. If you wanted to get real fun, you could probably get a place to weld on new material to the cam-in-cam, grind a more aggressive profile, and surface harden it, but I bet that costs a pretty penny. I don't know if anyone makes roller rockers for the car right now, but that could give you some more lift as well. If that still isn't enough, jack the compression ratio up. You might be able to do it with thinner head gaskets, which would also add squish to the motor, further improving power and possibly counteracting the compression when it comes to detonation. Good luck.

are Hennessey's power claims SAE corrected? He claims 50hp from headers while others the same style get 35-38. He's been known to market power figures that were just that - marketing

Just saying :shrug:

I have heard from more than one source the power McLaren/Dodge got out of these engines in testing. Well over 700 is all I am gonna say, but I have no problems believing Hennessey's claims. Who else makes 5 into 1 headers for the 08s? The only other header I know is the Bellanger and those are Tri-Ys, which won't make the same power up top.

check out the kooks 5 into 1 - near identical to look at and they are known to optimize their systems for power.

One should also never use the word Hennessey and McLaren in the same post. :lol:

[The Former PFR]

The Hennessey car was 608 RWHP SAE and 616 RWHP according to his dyno, just to clarify my original post.

I found the Kooks headers for the Gen III, but not the Gen IV (not that there is much of a difference). I didn't find any power claims made from Kooks for either model.

power claim is made here - and you are right, it's Gen 3 figures... hard to find stuff for 08/09

:yep:

I have a Tru-Trac diff on my GTS, and ill tell you without it. The power is just useless. So if your gonna go over 550rwhp, invest in a Quiafe, or a Tru-trac. Even with my shitty PS1 tires. I still get good traction in 1st and 2nd gear..

Kooks and American Racing both make great headers. I also personally like a 5into1 header better than a Tri-Y design.. Heres a pic of my AR stepped headers.

I also forgot a ported intake. Contact b3rndtt0ast. He can hook you up with some quality porting at a great price. I bet if you did a ported intake, headers, exhaust, modded cam, roller rockers with a higher ratio, thinner head gasket, custom tune, higher redline, and heads, you would be at 750-800 RWHP.

Those look awesome.

Yes they do. The car was in definite need of exhaust at the very least.
