I remember one 97 Regal I saw at Norwalk Buick Race day some years back.  It had a Turbo charged 3800 that made 608 HP.  The 60' times were lazy (2.2), but what a top end charge.  The car ran 11.30's at 130 MPH I think.  Running 11's in a FWD car is challenging.  Good luck.

Wow....WILD.....

Oh haha that's heavy kevys regal. Funny story I almost spilled a cup of my pee on it last weekend in james garage

...Alright

Haha......

Oh, the throttle body did get installed and it looks like it's working marvelously.




This is before I tightened the throttle body on. I did have to situate it on the adapter so that the bores lined up perfect with each-other between the TB and adapter since there's no room for the factory locating roll pins on the adapter.

It's beautiful!

Impressive work as always! I love the shot with the throttle body open and you can see the rotors.

Impressive...... yeah

Question for you - have you done anything to the halfshafts? I know a lot of people who break W-body halfshafts when they are playing with slicks. The CV joints can't take it. I don't see any other way to get faster than 11s - it's all about the launch and traction.

running stock halfshafts & stock output shaft which is something else I've kinda heard of possibly failing in an odd case but they aren't things I wanted to pursue preemptively

Yup I hear that. I believe the G-bodies got larger (and stronger) CV joints than the W-bodies. Just curious if you had trouble with them. Fingers Crossed!!!

At any point did you consider an M112/Gen III M90 hybrid?

I haven't really seen any compelling evidence to say it's better off than an M90. It'd guess it'd deliver better VE in certain states but if you look at it another way, it's like taking an M112 and giving it a undersized inlet and poor outlet placement. You get the decreased revs and that's where you can gain some efficiency in areas where it'd be starting to heat up a lot as an m90 but it's not all win even with a full on m112. You loose efficiency in lower ranges of boost and rpm where the 90 wouldn't be pushed at all as you're just turning extra mass needlessly. Bottom line IMO is it's only worth the bigger roots if it makes up for itsself when you push it and I'm not convinced the hybrid does that. It's definitely slick but I wanna see something about what it really does for peak power.

This guy doesn't go into too much detail about peak power, mainly just boost levels. Maybe we could talk to him and see if he has dyno results or something.

I think that Codith's impressions are bang on. Its a neat exercise, but the gains are documented as limited, especially for work required. If you had a CNC machine, or one of the adapter sleeves, and the snout and rotors, then sure. But to search them out, buy/beg them, just to shoe-horn m112 rotors into the m90 case... I mean, it helps to take a bigger gulp, but adds turbulence, rotating mass, and the last 10% of the rotors do nothing. Time, money, and effort are better spent on nitrous if you want that much power. I see it in the same category as doing it as a different approach. Like bolting on two m62s, or a jagm112, mostly because you have the parts, or just because you can.

Turtle, where'd you order your piping from?

The intake pipes came from Spectre. I found an online store that actually sells them at a reasonable price.
The part numbers for what I ended up using are 97400 and 97690.

Here's what we got

Revised intake for gen5, IC, northstar/85mm maf




I find that no matter what you do, it's really hard to get something that nicely works around the original coolant tank. It really interrupts any straight path from the throttle body to the hole to the fender. I played with a lot of pipes and found the only way I could really do it without putting a second bend and whatnot into the intake was to grind down the bottom leg of the tank a little for clearance and enlarge the hole for the fender toward the front of the car some - maybe half an inch or so. You kinda have to enlarge that anyway to use a 4" pipe and big filter. Overall though, I think this intake is pretty damn good - easier bends than my last one and as few components as possible. And my IATs are very consistent again.

Codith, do you still run with your MAF located further away from the TB? No issues?

Yeah. I didn't note any ill affect when I moved it farther away.

Good to hear. You are the only one I have seen with a MAF so far from the TB.

I had one rule. Go fast in the riv, go slow on the bike. I broke it last saturday and so now I'm a freakin statistic. I was going about 80-85 and the front tire on the bike got squirly all of a sudden. I lost control pretty much immediately and went down before I had time to do anything like slow down. Claim adjuster said the front tire separated which I kinda prognosticated because they were dry-rotted as hell since I got it. I was gonna eventually get around to replacing them. I won't eventually get around to something like that again...

Aside from lots of pain and the new ability to inspect my knee cap without an xray, no bones broken and the helmet did its job superbly and saved my head.
That's my shitty Memorial day weekend  

hope your-all's was better

Ow....

Ohhh no.......

Yikes.

Holy crap Cody! WTF! That's no fun. Rest up and get well. Glad you survived and are relatively okay. You'll be in pain for a while...

Good job wearing the helmet, bro.

I have the same rule that I tend to break too frequently. The boost on the bike is too enticing.

Glad youre still with us. I'd be pissed if you died and we never saw any videos of Turtle at the track!
