Just do it!

Done! I told the wife you made me do it.

Just ordered everything from Texas Speed but the lifters, head gaskets, intake, and throttle body. Those all should be on order tonight, and I'll hopefully get her put all back together Labor Day weekend.

I'm old...and will go really slow since this will be my first head installation in nearly three decades!!! At least these heads should be a bit lighter than those.

What fun is that. It's only money.

You don't mess around do you?

I did the H/C swap in my car with some help from a friend and a little beer on a Saturday. We had it running on Sunday and it was the first time I had ever done a H/C swap. I don't think you'll have a problem even for an old guy!

Hey, I resemble that remark.. Ridden hard and put up wet..

Thanks...I've turned a few wrenches in my day. Most of them over the last 20 years were turned on things painted green with turbine engines though. I doubt I'll have a problem, and if there's one thing that working on helicopters taught me...is to know when to stop and ask questioins.

And I had to make a decision quickly. My Bonneville just turned 200,000 miles, and she's showing her age, plus I've got work and other stuff going on and didn't have time to mess around. The one thing I still don't know is how she's going going to react down low. Since I couldn't get a straight answer to that question, I decided to find out on my own

Thanks for all the help everyone...I'll post my results and dyno sheets when I get them.

What a huge thread. Lots of good info if you take the time to sift out some of the hijackers bs. Other then that I think I just took a crash course on l92 heads and what does and doesn't work.

Thanks for the link Kevin

Wow! I hadn't seen this in a while and I forgot how much fun it was. Two and a half years later and I'm still waiting for a manifold for this thing. Next month hopefully the FAST will be out and we'll see how it does. I've got one coming as soon as they ship.

Thanks again Kevin for pioneering the virtues of the L92 top ends.
It appears now that a number of guys are incrementally raising the bar with these heads and once the new intakes are released I think we'll see another leap in power output.

Good work sir

Yeah Kevin,
This thread is the reason I sent my L92's to Richard.
I am right around the 1000 rwhp mark with 'em.

The project continues:

Last time on the dyno we were going down to 91-92 Kpa's so we knew we had a restriction before the manifold. I wasn't too concerned about it so did nothing. This past winter I wanted to cool the fluids a little so I decided to add a Dewitts radiator with built in oil cooler. I took the opportunity to address the intake restriction at the same time. I layed the radiator down so I could run a 4 inch down tube off the throttle body with a PowrMAF 100mm MAF..





This time on the dyno Kpa's only went down to 99 or so. I don't think you can really do much better than that. We picked up 11 RWHP and 10 RWT peak with some more in the middle. I'll post up a dyno chart tomorrow when Ed sends it to me. Current numbers 521/480.

Drivability remains perfect and has actually improved with the last go round. Ed's got it idling in OL and running CL above that. Previously it was tuned OL MAF. I picked up a couple MPG on the 180 mile ride home.

Thanks Ed and the guys at VA Speed.

Congrats Kevin !

I hope to be bragging up my car again pretty soon too, we've already discussed that though.

I'm ready now when/if the FAST 102 comes out.

allngn_c5

iTrader: (3)

Certainly appears so. Whats the 102 combo supposed to add 15 rwhp ?? If so and I were you I would be happy with that.............

Peace Kevin I have to go cut the grass for the first time. **** has gotten long, I did that to make the roots push deeper for less watering.

She really needed a good thorough goin through.

As always, thanks for the biz.

where do you find that 100mm maf and what do they cost?

Bruce is a really good guy. I got the couplers from him also.

Here is the dyno chart. Baseline plus the 4 inch downtube and the 100mm MAF.
