In keeping with Under Pressure's format, here's a build thread of my 2004 Jaguar S-Type R. Sorry for the Iphone pictures. I grabbed my digital SLR and didn't realize the battery was dead until I got to the parking lot where I wanted to take pictures. I'll take more shots another day...

Good job goblue90. She now looks beastlier but not too far from stock trim. 355 rwhp = approx. 425 chp.

 

You have been busy!

Looks great and should have performance to match.

Very nice! Quick question, do you know if your car has the revised pulley system?

 

very nice goblue, thank you for posting.

 

Sorry, I don't know. I've only had the car since May.

 

Your car looks great. Nice color choice of wheels and calipers.

 

Really good job with the car, great color matching perfect.

 

Looking great! It's a strange thing the Forgestar CF5 wheels, mine in 19" look like they're 20" and yours in 18" look like they are 19" (it's like they play tricks on the eyes). Maybe it's a result of the thin spokes going all the way to the lip. I think the 18" Wheels that these cars come with from the factory, whether Zeus or Vulcans tend to look like 17" wheels. Anyway, looks great and nice numbers!

 

No worries, I am trying to determine if the revised pulley system creates more power due to the better grip on the s/c pulley

 

Its looking awesome! Thanks a ton for posting up the newest pics on forgestars! Baddest green STR online yet!
Not sure if i would go 18 or 19's myself, guess i would have to price both out and make the call. Both look really good!

I like the CF14 design from forgestar as well... Decisions...

 

Wheels and calipers look awesome with your proper green color. Reminds me of my polo green Camaro, but obviously no where near as classy and sophisticated.

355rwhp (18% drivetrain loss) is 355/(1-.82)=433bhp
360rwtq (18% drivetrain loss) is 360/(1-.82)=439bhp

You started with what 317rwhp, so lets say 315rwhp because of the K&N, so that's a solid 40rwhp in bolt on's from stock. Being that you started semi low as far the average dyno (330rwhp), you could have near 370rwhp on other dynos. But as we know, dynos are for tuning, so I look forward to your track times!

Congrats on an efficiently modded and beautiful car.

 

For ever I have wanted a polo green C4 corvette (or even a c5) with the black leather but its like trying to find a needle in a hay stack.

Every thing looks great, now you just need to do the EPB to match your other calipers.

 

what kind of paint did you use on the calipers? Where did you get it?

 

If you have the revised pulley and belt it's easy to tell.

The new setup has a double sided belt that is ribbed on both sides. The old setup has a belt that is flat on one side and ribbed on the other. The pulleys changed too but the belt is the easiest to check.

Thanks tbird6. Based on that, I do not have the updated pulley system.

 

I used caliper paint and purchased it from g2usa.com

 

rasputin, I believe AVOS advized useing 17% drivetrain loss when calculating the "S's" rwhp. If this is the case then we may be looking at an est. 440 chp?

 

We need a JRG STR meet

 

Avos suggested a 20% drivetrain loss factor with this dyno (that uses two drums) vs. a 17% drivetrain loss for a dyno that uses a large single drum. See here... https://www.jaguarforums.com/forum/s...42/#post573115. 355.2 rwhp/.80 ~ 444 chp. I'll hopefully be taking the STR to the track soon so I'll be able to supplement my dyno slips with track times.
