Engine's Out! Winter build has started

[wraith]

You will love the 750s. I went out for a spin and on a very rich tune, spun the rear tires at around a 40mph roll in gear by just pushing the throttle down halfway. I need to get my diffs in I have a stock 4 bolt with about 20k miles on it and Stage III DR heads. I hit 1.5 bar under 40000rpms in 2nd gear

I like the custom crashbar much better than cutting out a section of the original.
Will it collapse at all or is it just solid?

it bolts to the stock bumper shocks.

nice.

are you able to run 1.5 bar on 93 octane?

I got a good question in a pm that I'd like to post, It has to do with why I'm only running 550cc injectors and what my power goals are:

"I didn't want to swap injector until the engine is at least broken in. If and only if I max these out to 100% will I go bigger. I am running 7 PSI over base fuel pressure and injecting alcohol, so the 550s should go pretty far.

I wasn't really planning on running much more than 500AWHP. I don't mean oh my dyno read 550AWHP one day, I mean backed up with track results, and the car actually makes it every day and doesn't blow up for years. If I do not trap north of 120 (hopefully 125) on pump gas I'll be disappointed.

I went with ported heads and the bigger turbos just to make it easier. I'm sure I could've got by fine with DR650s, but fast turbo response is one of my top priorities. Even the 19Ts were a bit laggy for my taste. I don't like having to downshift and wring the car out just to drive on the street and have fun on backroads and even just changing lanes. Maybe my old engine was just worn out enough to make them feel non responsive or the tune was wack, I don't know, but in the end they felt like a big turbo car without the big turbo power.

I actually miss my car when I first got it. It had a 9b and a DSM 13G. Holy shit that could spool up fast. It was like driving a big block v8. Just changing lanes on the interstate in 5th you could easily hit 15 PSI in a second. I'm hoping to recapture some of that magic and keep the car reliable. This isn't really a balls out build, just a good combination of parts that I'm only going to run at 80% most of the time."

sound plan. is 1chp per cc of injector sufficient though?

with the fuel pressure turned up and the alcohol injection it should be close to 550AWHP of capability, even at 11.5:1 AFR or so.

I think that is going to be enough for me. Hell I was probably doing good to make 400AWHP before. This will feel like ludicrous speed by comparison. If I end up needing more power than 550 it is going to put a lot of stress on my bottom end. I'm not going to chase power to the end unless someone like Ray has his hands on it.

That last 10% of power isn't worth 100% more stress on parts to me. I don't need to make 600AWHP to be happy.

Hey Forest, PM me the specs on your IC Core if you don't mind.

[Chris@Rvengeperformance]

it is just the standard 3.5" thick one that comes with the ETS kit.

[FeaRpb]

Ah okay.

i see what you mean, but is the bottom built?
