Well to mix things up a bit I guess.

Today I recieved my Buschur Racing 4in. Race FMIC. Along with their short route IC pipe kit. All looks real nice.

I am sending out my sending unit sometime this week for the Double Pumper fuel pump setup. Also orderd the BR fuel rail. Probably going to stuff some 1600cc injectors . Tryin to setup for E85 for my low boost setting hahaha, low boost

Its looking like even the smallest planned turbo I am considering running will even max out the 1600cc injectors on E85. Even with the double pumper and fuel rail. But the fuel setup should be enough on normal gas and race gas.

 

Correct me if I am wrong here Dan but aren't the 4G6X series engines an interference design?

 

that is exactly what i though, but the article says different.

something tells me there is more to that story though. i have a hard time believing it beat not only the new evo mr, but also the new sti, and several other more expensive cars. who knows though, maybe chevy pulled their heads out of their asses and got really lucky with the new ss.

 

. Remember when Nissan was almost dead. They shoved a decent v6 in anything with wheels.

New marketing strategy at GM
If we build decent cars people might buy them.

Brilliant!

Time for Mitsu to step up to the plate, get some weight out and more power in the X.

 

it's not the power i have questions about really, it's the handling.

you can make straight line power in any car with the right parts, i just really can't fathom a cobalt torque steering it's way around VIR faster than many other cars.

 

They are extremely interference. If you loose time on the smallest cam 4g63 ever, a 90 turbo model, you will hit valves at only 2 teeth out or about 8 degrees. An evo, with higher compression thus pistons closer to valves, and with bigger stock cams let alone aftermarkets will make contact very quick.

 

Thought so thanks. I'll be doing my timing belt early on the EVO.

Probably a good time to get cams in as well. Even if they aren't as great on the IX's.

Another technical question for you if you have a minute.

With Mivec, if I get aftermarket cams, say HKS 272 can I make the idle much more stock like with the mivec tuning then the cams on the 8 were?

 

Yes the mivec allows for much more cam with a steady idle. I believe you run a special mivec grind however. I would recommend HKS for a drop in affair and the 272's are a nice touch that matches off boost power, provides more midrange, and great top end compared to stock. As always, even if HKS doesn't recommend it, I would recommend a set of valve springs. PM me and I can fill you in on the things I learned about valve train components the hard way.

 

I'll be in touch. Thanks.

I am still kicking around that downpipe with the cutout. and if I do that then well, f-it, cams/fmic/blah blah blah would be going on. Maybe even one of those fancy new red turbos.

Any thoughts on those?(the red turbos I mean.)

 

It keeps getting bigger and bigger. Forget that race, man.

 

The Red turbo is basically a GT30 compressor wheel , stuffed into a stock appearing housing. I am not sure what turbine is driving this wheel though.

But it makes big power. look into 9sec9 threads. nuff said

 

I really really really like the stock 9 turbo. However if you need more, then bolt on turbos are an obvious choice as the setup tends to be cheaper, more reliable, and stock appearing. If it is a true street car/daily driver then this is what you need. As soon as you move into a tubular exhaust manifold and external gates all the problems start. Unless you like carrying around wrenches and spare wastegate seals in your car all the time stay internally gated stock turbo manifold.......

 

The time difference claimed by C & D was a difference of .3 seconds. Reading the breakdown of corner entrance and exit speeds, I cannot possibly see how the Cobalt SS could be quicker in some turns than a X MR. Not to mention the SS putting down higher lateral G's in some turns??? Not possible. My suspicion is that the MR wasn't setup properly. Not in S-Sport mode, had ASC on, or had AYC off and didn't know how to drive at all...

Either way, the GSR is the better performer of the two X's. The tranny on the MR might be great as far as innovation and quickness, but the launch is where the times really struggle. It's a bog every time on every video I've seen. Even with the Stig driving. And the 0-60 & 1/4 times show just this.

Either way, a $400 flash for the MR would really help things out. But if you really want to mod and track, the GSR is the better performer.

 

Not to worry. My mod money war chest was all invested in Lehamn brothers stock.

 

all your intake valves looked bent to me eric
