Anyone have any REAL engine mods done?

Thanks Yeah, we wanted to do it right so we did get a baseline dyno so we know what we started with. We are trying to get the dyno setup for tommorrow. Im pretty anxious about it because I recieved my S1 in the mail yesterday but promised my tuner I wouldnt install it untill we get the dyno results from his head porting. Keep in mind, this is on my SRT..not the Cruiser, that may be next!

thanks for doing the engine work.. I am on the edge of my chair.. this is a catch 22.. I know everyone is waiting to see the results and where exactly the engine is weak and strong.. but also know that shops dont make money by telling everyone what they did.. but selling products..

possibly if your neon worked that well.. you should have him to work on your PT.. do more before and after #'s and I am sure your shop can set up prices for work done..

Im really sorry I dont have the dyno sheet in front of me, but I can tell you that it is all done and running and dyno'd!

Stock, my SRT was holding 14psi but now it holds 11. This is attributed to freeing up the restrictions and getting the air to flow easier hence the turbo doenst have to work as hard. The peak dyno numbers werent quite as much as expected, as they were within 10 (hp and tq) of stock. However, I was able to pick up 20-30lbs of tq in the mid range! Its obvious that the stock exhaust is a restrictive component, so thats probably the next to be switched. The car feels like it picks up power faster and holds it stronger (if that makes any sense whatsoever). It pulls harder than before. The night after we got it put together, we went test running it on the streets and ran into another SRT from the local forums. He had a WGA and boost controller set to 17psi. Remember, mine was stock except for the headwork. We raced a few times but was able to pull 5 cars on him by 110!

This was more of an experiment to see the results on a stock engine. Although, we thought it was going to shoe better, the really interesting part is when we installed S1 at the dyno. After all the head porting runs, we put in the S1 just to see. Mopar claims 240hp/260tq out of S1. We ran 268whp/294wtq!! The theory is that more gains (than the norm) will come with each additional mod we add. I will have to keep you all posted on that.

Part of the issue on the numbers is probably the psi. Remember what I was holding stock and then what it does now? To be completely accurate in the actual gains, we would have to adjust the boost back up to the same level. The ECU compensates for the additional flow and backs off the boost. Ill get the dyno sheets up as soon as I get them back. My tuner has them at the moment.[8)][8)]

That's very impressive Hoodie! You got more of a gain than when we used to get doing the same on small block chevy heads. Is the head and manifolds all you did? How long did it take, and was it alot of work? And of course, what was the total price? Definately worth trying out! I guess if you got a EBC or MBC, you could raise the boost levels and really tear up some asphalt![:X]

yes, the head was ported to match the 1mm oversized REV valves, both intake and exhaust ports were ported, the intake manifold was ported, the exhaust manifold was ported, and we put a 5 angles on those REV valves. My car was down a month total. Lots of flow bench time....shoot, installation alone says a day and a half for installation (Alldata).
