smrx8, how did acosta screw ya? I was looking into them but they are overpriced and I have only heard bad things, so they are out!

yeah big time the installed springs on my car when i decided to take the out they were cut,they did a weld job on exhaust manifold thaT a 3 yrs can do better.People told me the same **** that they suck but i tryed anyway learned my lessen the hard way.
theres 2 shops i heard good thinks about were phil takes his car and smokin joe racing also ..

having done TONS of motors in fc's, fd's, and the 8's, i'll tell you i'd rather do a motor in an 8 than anything. EVERYTHING is really modular now. you can pull a motor from a stock car (nothing removed) in about 2-3 hours, and even less time if you hustle. no more pulling harnesses through the firewall. :D
installing them is almost as easy too.

Porting? Would that even give any gains? I thought you cant port the exhaust ports because of the water jacket? You probably can...just very little. Oh and Wow you just brought back a VERY old thread rofl

lol I brought it up because I am interested in trying to do a street port in the renesis.

This goes back to RotaryGod's attempt to port Charles R. Hill's engine. This was done last summer. The intake ports are large enough so some smoothing was what was mostly done there. The exhaust ports are the ones that could use enlarging. But, when he tried, he keep braking into the water jackets. These jackets are large and near the surface around the exhaust ports for cooling purposes. This makes any significant changes in the exhaust ports impossible. You can't even streetport a Renesis. All you can do is clean up and smooth these ports.
Given that the port shape controls the duration and timing of the opening, a bridgeport is probably akin to driving around on a race cam in a reciprocating engine. I've never ridden or driven a bridgeported REW, but I'd imagine that the driveability of it goes to crap. I personally would not do something like that on a street car.
Then again, were you to bridgeport the intake ports successfully, what would be your plan to get your exhaust ports large enough to balance it out? Is there a specific reason why you would want to shift your torque curve higher up in the rpm range? I don't think you could actually increase the VE of the engine (it's already capable of topping 100%) so I don't know if a full porting would be able to produce any increase in peak torque. I guess if you make peak torque 1000 rpms higher, you do have more power but the car in DD use would probably actually be slower.
So - what would you exactly be looking for that you think drastically altering the intake/exhaust geometry will do?

In a few weeks I am sure I will be posting up the results of a long dyno session that the BHR crew plans on doing with my ported Renny. Right now, with a pre-loaded MM map from the Cobb we saw some VERY interesting torque characteristics. For example, with a 3" catless midpipe, a Borla cat-back, and the factory air filter/airbox, my engine was STILL making significant amounts of torque at 9,500 rpms. The plan is to max the rev limit out at 10,000 and see what the torque curve looks like. For certain, there is MUCH improved driveability and 25 mpg on the X-way. As for roll-on and tip-in torque; I don't downshift from 6th gear to pass anybody. Further, my car continues the acceleration from 100-135 as it does from 70-100. So, from 70-135 it is a steady pull with no power drop. Both MM and tdiddy can attest to this and MM was actually humored by the fact that my dash chimes LONG before the engine runs out of power OR rpms.
We are already surprised by what we discovered but I want to make sure we have dead-on accurate dyno charts before we start showcasing/discussing anything.
Equally important as the porting is the tuning that MM has done with the Cobb. Remember, I am using a basic map included in his stuff. He hasn't yet had a chance to play with a ported Renesis so there may be some new info he can glean from his time with my car. While that is going on we will also be installing a BHR flywheel/clutch kit on HIS car and we can get his input on the difference a reduction of 8 lbs. of rotating mass can make. I already know.
