Well, I think it's a Bosch. Can't find the word "Bosch" anywhere on it, nor on the receipt from it's purchase. But the numbers are: 0 120 488 176 And if you Google "Bosch" and that number, it returns an alternator. Interestingly, the Bosch website did not match on the parts search using that number. The main body is roughly 5" in diameter. Hope this helps. Steve

Total "bolt in" with no re-wire. I took it to a local place to be rebuilt (the shaft had a huge amount of vertical movement), and they basically said forget it (after they took it all apart), they happened to have a new replacement unit. Steve

I replaced the alternator on my Crossflow about 3 years ago. I believe it's a Bosch, and is essentially the same size as what I had. It definitely does fit the categorization of "smaller". I'll get the specfic model info tonight and post it here. Steve

So, sounds like it's based on the $ amount. Tom - Had the Crossflow rebuilt, so with the engine out thought I should replace the clutch. Hadn't had any issues with the clutch, but what the heck. Also replacing the rubber engine mounts. I'm picking up the engine on Saturday, after which I'll post the dyno sheet. While not impressive compared to Duratec's, etc., I'm happy with the results.

I recently made a parts purchase directly from Caterham in the UK, which I've done multiple times. Yesterday I received an invoice from FedEx for "Customs Duty" and an "Advancement Fee". This is the first time this has happened. It may be due to the dollar size of the purchase, but really don't know. Anyone else been charged these types of fees on international purchases? Steve

I'm not sure I'd put too much stock in the Caterham hp estimates. My Crossflow was originally the same spec as yours, and then was upgraded to the 150 hp spec by changing the cam to the Kent 244. I did a dyno day about 5 years ago, and I think I had 109 at the rear wheel. I missed both a BDA and a BDG that Craig Chima was selling, so opted to go ahead and "refresh" my Crossflow. Curtis Farley, who is a fairly well known Formula Ford engine builder, is doing the work. The only major component upgrades are forged pistons and SCCA SCAT crank. The crank should allow me to comfortably move my redline from 6500 to 7000. Already have double valve springs and roller rockers, but the valve springs are being replaced. Some head work had been done, but Curtis said it was like they got 75% done and then stopped, so he's "cleaning up" the head. Valves are slightly larger and, in Curtis' words "kinda slick" - although he didn't give me any details as to why. He thinks the compression ratio was below 9.5, but expects it to be slightly over 10 when he's done. No surprise here, but Curtis hasn't/won't make a prediction of hp. I'll be happy with a true 150 at the crank. 175? From what I've read on Blatchat, it's possible. But I think it's also expensive. For starters, a steel crank - which runs around $2-2.5k (the SCAT crank is less than half that). Haven't given up on converting to a BDA at some point, but this will tide me over for a bit. Steve

This is a personal plea to The Stig to attend and help me defend the honor of the mighty Crossflow. Stuart was charmed by the wiles of the BDA, and has left the fold. Steve

I'm interested. Possible to change our entry with Trackdaze from both days to just Sunday, then everyone sign up with LTW for Monday? Which could then turn the Saturday Trackdaze into the "optional" day? Steve

The Wallage Crossflow book lists 13-15 lb ft for the intake manifold. Steve

Nick - How hard is it to line up/aim the Replay? Do you just sight down the barrel?

Finally going to bite the bullet and purchase an HD camera for track days. Was planning on purchasing a GoPro HD3 (probably the Silver), but then looked at the Replay XD1080 and thought it might be a good option. Primary question has to do with the lense. GoPro is 170 degrees, while the Replay is 135, which apparently reduces the fisheye look that 170 provides. The GoPro is the easy choice. Anyone have a Replay? Thoughts? Steve

I would think you might end up having to develop a map specifically to pass emissions, even if it makes it run poorly overall. Might be a reason to not go with Weber Alpha kit. Steve

Another AX block Crossflow owner here. My engine is at the start of a rebuild, and while my exhaust seats were changed to hardened, my intake weren't. Interestingly, they apparently have held up fine. But, they are going to be changed as part of the rebuild. I had my distributor recurved last year (Advanced Distributors), and it now needs 16-18. I thought that the cam had a large impact on the advance. I know on Blatchat that 14 seems to be the general recommendation. Steve

Carl - Don't have any info to offer (although I also have a Crossflow), but I am in contact with someone in the UK who is in the process of converting his Crossflow to injection. If you PM me your email address, I'll send him an email asking for info on his project and include you on the email. Steve

Just registered. Snagged 74 (no numbers with curves - much easier to make with tape ). Steve

I thought the decision to be made was between the new LTW group and Trackdaze? Nova indicates that LTW hopes to have dates in the next week or two. I'm fine either way, just wasn't sure that a decision had been made. Steve

I had the same problem with my '98 Crossflow Caterham, and it was the rubber engine mounts. They had collapsed and the bottom of the carbs were hitting the frame member on hard left hand turns creating an air leak. They've improved the design (somewhat), and they are supposed to last longer. Steve

Mon/Tues allows me to visit family over the weekend, but no real preference for me. The Trackdaze site states that there will be 5 run groups that weekend. Steve

It was me and the Crossflow pedaling as fast as we could. Scott and I quickly agreed on the strategy of heading to the back of the grid as it gave us a few laps before we started giving point-by's to all the high end equipment. My speedo was acting up (really, it was!) but think I saw 110 or so a few times. I'd redline in 4th and then sit there for a bit before braking. Tried 5th once or twice, but it didn't seem to make much difference. Still, unbelievable facility, and we had fantastic weather all 3 days. Croc - I'm pessimistic about COTA having track days after this year. The track isn't really setup for them, and I'm not sure how thrilled they were to have us. The weekend was actually canceled for a time (after everyone had paid and the check had been written to COTA), but then they changed their mind again and allowed the weekend to happen. Hope I'm wrong, but we'll see. I haven't received my photos yet, but will post some when I do. Steve

Driving down the (more or less straight) road with your turn signal on is very Seven-esque. Steve

... but to paraphrase an old joke about doctors, hopefully the patient didn't/won't die. Steve

Scott - I would think that just "normal" snap studs would be fine for the boot cover. The "pull the dots" are directional, in that you can't unsnap from one side of the snap, and can only undo from the other. I used them for the front snaps on my half doors, so that they wouldn't blow off from the wind, but don't think you'll have that issue with the boot cover. My 2 cents. Steve

Mike - Is that the actual date for this years NJMP event? Steve

I thought that the series/edition was related to the age of the carb. So a "2" would have been made - well, a while ago - maybe the '50's (?). It may also be related to where the carb is made - maybe. I thought the 151's were made in Spain. This is not based on any actual research - so, I could be way off. Steve
