Talking Poll - Ok, the turbo's are out, so how long til somebody blows an engine? :)

Ok, the kits are out, people have thoughts of 500WHP 8's dancing in their heads, and many folks think you can make more power buy just turning up the boost level.

So, I'm getting a lawnchair and a cooler full of beer out, sitting down and watching the mayhem begin. For those that would like to join me, how long til somebody blows an engine? Not that I wish this on anyone, but somebody is going to get greedy (not Greddy) and pop a good motor. I guess we need a source of housings for port testing, so its not all bad...jk

with the side exhaust ports, you're just about guranteed to need to replace rotor housings with every blown motor.

I will place a bet that at least the first 5 people will have transmissions go before the motors. No way they can hang with that kind of HP. The first clutch drop and their gone. Either tranny or clutch.

I am going with a 5 speed box from a 3rd gen rx-7. I think if they do break(apex seals) that it would not damage the rotor housing because it has no place to escape to cause damage. I think they will just fracture all over the place but I could be incorrect.

where'd you get this from? at a low level you should need to replace anything with a blown motor (well the clutch but that depends on how much more torque it's putting out). just what i've understodd from it. and at a lower level the tranny should be okay as well (like 250ish whp).

but doing high rpm bombs (no slip) is bad for any tranny. so it' s agood thing i don't drag or stoplight race:p

I say two months....I am going to side with slims8, I really believe that once people start hammering on their car that our drivetrains are going to start failing. That has alwyas been a source of contention for me. And on a side note, I also believe we will see failures when someone begins to manipulate the low boost setting after some time behind the wheel...There are probably some that will be content with the low boost stock setting, but many more will start upping the boost to find the limits of the system. And then we will see the fuel delivery issue having to be dealt with. And the first posts dealing with rebuilds.

I have already seen a renesis blown from forced induction, so where is -4 months on the poll?

I am not sure what you are trying to say? Guitarjunkie is talking about because of the side exhaust ports there is more chance of the rotors damaging the housings upon detonation, the most likely cause of a blown rotary motor with forced induction. The housings are the parts of the engine that house the rotor in which it spins. If they are nicked beyond spec then they have to be replaced with a rebuild.

Why would a clutch need to be replaced with a blown motor? Maybe you are thinking about doing performance modifications while the engine is blown before you put the motor back in the car?

nice, alot of us do have sick senses of humor :D.

Personally, I like a good micro brew, like St. Arnolds Amber Bock here in Houston, but since this is a more international group, how about a cooler of Bass or Guiness?

Some entrepreneur out there should probably get cracking on an alloy gearset for the Aisin transmission. Either that or a kit for a T56 swap. :p

While we're talking about major modifications, maybe some lower compression rotors are in order too.

My suggestion to anyone that is going FI is get the car over to an experienced rotary tuner. The first thing is to make sure that the base maps on the Emanage are safe. Get it on a dyno and check the A/F. I have been tuning rotarys for a few years and I never have a car that uses the same settings.
If your motor happens to lose a seal be prepared to spend some money. The seal is probably going to take out the rotor housing with a possiblilty of taking out the end plate and rotor. Also a good chance of it going thru the turbo and causing damage.
Adding a turbo is a whole new game and the margin for error goes way down.

Well, as some of you know, I am in the process of installing the Greddy kit on my RX-8. The only problem I forsee is with the clutch life going bad a lot sooner than normally. I've smoked the clutch a couple times (wasn't paying attention one morning and feathered it out at 7500rpm!). I don't plan on going higher than 6.5lbs of boost. So I don't see the engine being blown. The transmission parts other than the clutch will be just fine, especially since I don't drop the hammer but once in a blue moon. You have to realize that there are other forum members that currnetly have turbo or 75 shots of nitrous in their 8's with no trouble. Again, time will tell. We'll see what happens.. There wasn't a catagory, but I don't expect that I'll blow an engine, but I do see my having to replace the stock clutch with a heavier duty clutch withing the next 4-6 months.

Sub 1 month I reckon.

The people getting the kits are performance orientated enthusiasts so the need for speed will be fueled by a curiosity to up the boost.

I don't think anyone is pointing at you specifically, philodox.

I put in my vote at three months...and I'll take a Guinness, thank you.

I'm hopeful someone comes out with lower compression rotors for our everyday, street applications - and I'm very curious to see the outcome of Richards Axial flow project...

I think I will grab that lawn chair too and wait until my baby is paid for. So in about 4 years from now they should have this turbo/supercharger stuff all worked out and working well in about 4 years. Then I can really get into it, adding a turbo and a aftermarket clutch. I know, I smoke my clutch way to much as it is, not closly looking at the rpms...I'm probably going to need to get a new one anyhow, without having a turbo, the way I drive. I need some racing lessons....***sigh***

What makes you think that? They have to be built better than my stock Protege tranny, which (knock on wood) is holding up. Guys put well over 300hp through them, and they're not even made well.
