MichaelD Posted February 26, 2013 Author Share Posted February 26, 2013 I could be wrong but I think anything over 230 -250 will be a real strain on a T-9. Link to comment Share on other sites More sharing options...
Croc Posted February 27, 2013 Share Posted February 27, 2013 Would the duratec with a supercharger fit in the narrow chassis I have ? Cranking this up to 330 hp would be fun. Not sure if it mates up to the T9 5 speed I now have but perhaps the T9 wouldn't handle the added hp. Good suggestion, thanks Mike. Mike Yes. The R600 is based on the S3 chassis - same as yours. so the Duratec should just drop in. The T9 would not be able to handle the torque demands (well not for long anyway!). So you would need to change gearbox. Caterham 6 spd box is ok up to 300hp area from memory. The sadev sequential is used in higher horsepower applications so should be ok marrying up to a Duratec with this Sp300 level horsepower. The Sadev is designed to replace a T9/Cat 6spd as a bolt on replacement. Link to comment Share on other sites More sharing options...
westy turbo Posted February 27, 2013 Share Posted February 27, 2013 Will be the limit about there,now as far the conversion on your narrow, i would go for it,and you design as you move on the best way you can, dont forget, we own kit cars ,and we also adding stuff on top of it,so it will need something here and there....if u know that you got the right people to finish the job, do it!!!

Klasik-69 Posted February 27, 2013 Share Posted February 27, 2013 Now the big question.....................how much does the SC duratec coupled to the sadev sequential gear box cost ? If the duratec with a SC can fit in the narrow chassis, then is it possible to add the SC to the Zetec in the same chassis ? We have a driver in SCCA Atlanta area running a locost with a Miata motor/tranny combination who has a turbo on it. Everything he added is outside the shell. The intercooler is sticking out the side, as is the oil cooler and some of the exhaust. It doesn't look very good (and I'm being very kind) but he is faster than anything else out there by a long shot. He has videos on YouTube of him running the Tail of the Dragon. I talked to him at Road Atlanta where he was running around 1:30 per lap, faster than a lot of formula cars. If I remember correctly, he told me he was pulling 330 rwhp and using the stock Miata transmission. For that matter, I believe Skip is also running a stock Miata transmission and he's well above 300 hp. Is the Miata tranny that much better than the T9 ?

Kitcat Posted February 27, 2013 Share Posted February 27, 2013 My memory is the Miata transmission is a big, stong, heavy lump. Skip will know for sure. Birkin USA (Texas Motor Works) has a $5K supercharger kit for Duratecs and, at last report, was developing one for Zetec versions too. Since the stock Birkin engine bay is almost the same size as the Caterham, this mite be worth exploring. Bumps rw hp to 300 and has a nice fat/flat torque curve. It runs on the T9 transmission.

Guest Terry Posted February 27, 2013 Share Posted February 27, 2013 The R600 Duratec SC will not be available in LHD as it won't fit. That's CC response when we tried to order one in LHD Link to comment Share on other sites More sharing options...

Good suggestion, I'll check it out. If I could keep what I have and just add on to it, it would be best option. Many people say that the Zetec motors don't do well with turbos or SC, not sure why unless it's a durability issue. I always thought any motor will benefit from forced induction. The R600 Duratec SC will not be available in LHD as it won't fit. That's CC response when we tried to order one in LHD I guess the intake on the left side of the engine gets in the way of the steering shaft. These cars are such a tight package (which is a good thing) that getting everything to fit can be difficult. Link to comment Share on other sites More sharing options...
Kitcat Posted February 27, 2013 Share Posted February 27, 2013 I dont think Zetecs have a turbo issue. TurboTom (1turboFocus), who posted earlier on this thread, has done tons of turbo Zetecs. Visit the focusfantics.com forum (where he mostly posts) for more info abt turbo Zetecs than you need or want to know. Link to comment Share on other sites More sharing options...
scannon Posted February 27, 2013 Share Posted February 27, 2013 The Miata 5 speed trans weighs around 85 lb. It fits in my SV's tunnel after the mods shown in my earlier post. It has handled 300 HP and 265 torque with much abuse for 15k miles in my Caterham with no problems although I do not do off the line burnouts but I do speed shift it when running up the gears at WOT. The trans in my Miata has handled 280 HP and 260 torque in a car that weighs 1,100 lb more than the Caterham with no problems for close to 80k miles. The Miata transmission is one of the sweetest, shortest shifting transmissions on the planet. (I might be just a bit biased) Link to comment Share on other sites More sharing options...
Klasik-69 Posted February 27, 2013 Share Posted February 27, 2013 Has anybody heard of this outfit ? http://www.rotrexsuperchargers.co.uk/Rotrex/pages/products/engineDIY/Ford20/prod_ford20.html They have the bracket for mounting the Rotrex supercharger to the Zetec which seems to require the repositioning of the alternator. The alternator is also part of their kit. However, no ducting, piping, or intercooler is included but it does show how its plumbed. Interesting.

S1Steve Posted February 27, 2013 Share Posted February 27, 2013 Nice compact kit. I would do the plumbing alittle different and not have the hole in the top of the hood and the filter poking out the side. I would also find out what needs to be done with the ECU. Some reseach would need to be done first.... I'd like to have it on my S1. Link to comment Share on other sites More sharing options...

Klasik-69 Posted March 1, 2013 Share Posted March 1, 2013 Klasiak we have been running Rotrex superchargers for nearly five years now. I love them. On the Duratec or the Zetec ? I've seen the kits for the Duratecs which have the exhaust and intake on opposite sides of the Zetec but I have yet to see an S3 chassis Caterham with the Zetec and the Rotrex SC. There is a company in UK that has the Zetec partial kit which includes the mounting plate, the Rotrex SC, a replacement alternator and the idler/belt assembly but they omit the intercooler and piping.

Kitcat Posted March 1, 2013 Share Posted March 1, 2013 WTex uses it on a Honda S2000 engine, I think. Link to comment Share on other sites More sharing options...
WestTexasS2K Posted March 1, 2013 Share Posted March 1, 2013 Yes we use Honda engine. We built our own bracket for the Rotrex. Kraftwerks is the importer for Rotrex in the USA. They have several kits for Honda models but were working on other systems too. I hadn't been to their website lately. TTS in the UK makes systems for more varieties makers. Since Ford is popular in Europe he might something that would work. Link to comment Share on other sites More sharing options...
Klasik-69 Posted March 2, 2013 Share Posted March 2, 2013 Yes, I contacted TTS. They have the bracket, SC and a replacement alternator. I still have the intercooler issue, and seeing if I can remap the Pectel ECU for the SC. Roughly $3900 w/o inter cooler or piping. $350 for an intercooler, $100 for piping, and ??$ to custom make a new longer nose cone. Link to comment Share on other sites More sharing options...
MichaelD Posted March 2, 2013 Author Share Posted March 2, 2013 (edited) FWIW: this was posted in yesterdays SCCA-DMOD-EMOD@yahoogroups.com: "the ecotec 400 lb was in a running state as in intercooler, flywheel, fuel pump, water pump, all electronics, etc. this website appears to indicate a 400lb ecotec engine can deliver as much or more power than any v8 which weighs at least 200 lbs more," "it appears the 500+hp ectotec can be built for under $7000," http://shop.zzperformance.com/store/default.aspx Edited March 2, 2013 by MichaelD Link to comment Share on other sites More sharing options...
WestTexasS2K Posted March 3, 2013 Share Posted March 3, 2013 Ive good things about the Ecotec. Im not sure how it can be configured to rwd. I guess the Saturn Sky and Soltice used them in RWD format. I think they both have been discontinued. Link to comment Share on other sites More sharing options...
MHKflyer52 Posted March 3, 2013 Share Posted March 3, 2013 The Ecotec engine can be adapted the same way the Ford Duratec engine is by changing the bellhousing an some other parts. The Ecotec was orginally developed for the Opel line of autos in the late 80's to early 90's to my knowledge and is still used in the GM Cadalic line so they should be avaiable for quite sometime. Just my belief that both engines are a good power plants and can make some serious HP with some additional componets. Link to comment Share on other sites More sharing options...
