Bill Shurvinton Posted October 13, 2003 Share Posted October 13, 2003 Following the unconfirmed reports that Arnie has upped the ante and that big boys now need 300BHP to make the grade I was wondering who else has specced engines of that level and what the cost was? I'm still working out the costs of a 300HP NA rotary, but will get back to you on that. Bill Link to comment Share on other sites More sharing options...
Red SLR Posted October 13, 2003 Share Posted October 13, 2003 Have seen a Civic Type R engine running over 300bhp and will fit in a 7.... cost was not that bad from what I hear.... Link to comment Share on other sites More sharing options...
Jason Plato Posted October 13, 2003 Share Posted October 13, 2003 Hmmmmmmm 300 bhp I'm sure Arnie will be along soon to reveal all .......... Whatever happened to the V6 nissan lump that we were going to shoehorn into a SV chassis ?? That would make 300 bhp on throttles and mild cams . Next engine for me will have to have minimum 275 bhp . I simply want to try a tame that sort of power through my 205/60 32r's Dave Edited by - Dave Jackson on 13 Oct 2003 15:30:39 Link to comment Share on other sites More sharing options...
dino ferrana Posted October 13, 2003 Share Posted October 13, 2003 What did happen to the Nissan lump? Dave get help now! Link to comment Share on other sites More sharing options...
Jason Plato Posted October 13, 2003 Share Posted October 13, 2003 Did anyone see the picture in Race car engineering of the bare unpainted Caterham chassis with the V8 bike lump sat in it ?? , exhaust manifolds all made to fit . The article also states that a Caterham test mule will be ready early autum . Anyone know of this car ?? dave Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted October 13, 2003 Support Team Share Posted October 13, 2003 Someone on here has a Cosworth Turbo installed - IIRC that's got about that sort of BHP. Yellow SL #32 Link to comment Share on other sites More sharing options...
dino ferrana Posted October 13, 2003 Share Posted October 13, 2003 I believe that someone said it was running at Donnington Kit Car Show. IIRC it was a lot slower than Caterhams R400 demonstrator apparently. Link to comment Share on other sites More sharing options...
Red SLR Posted October 13, 2003 Share Posted October 13, 2003 I have seen the K series turbo at Robin Hood Bay hill climb - mighty fast but not that cheap. The Honda route is way cheaper... Link to comment Share on other sites More sharing options...
Doug phillips Posted October 13, 2003 Share Posted October 13, 2003 Hmmmmmmm 300+ bhp ❗ Just cos you have the power, does not mean that you are a fast driver. I would like to see a James ver Arine at santa pod. 😬 😬 Just remember power is all about "how you put it down on the road". 😬 Doug, Su77on Se7ens See our web site here Link to comment Share on other sites More sharing options...
dino ferrana Posted October 13, 2003 Share Posted October 13, 2003 I would imagine that the Cossie Turbo would be pretty heavy. I think if I were to go turbo I would have to look at Hayabusa Turbo a la Radical. Link to comment Share on other sites More sharing options...

Bare Posted October 13, 2003 Share Posted October 13, 2003 Could just buy and install a Honda S2000 engine AND 6 speed.. surprisingly light quick and 240 hp as a start.. 6 speed is also one of the best shifting boxes yet made. And if some can manage to squeeze serious power out of a Metro engine.. :-) Link to comment Share on other sites More sharing options...
martinwhitcher Posted October 13, 2003 Share Posted October 13, 2003 Bare, I think you will find it's the civic type-r engine (K20) not the s2000 Martin MW 51 CAT Superlight No.171 Link to comment Share on other sites More sharing options...
Normans_Ghost Posted October 13, 2003 Share Posted October 13, 2003 Is'nt the problem with turbo's that there's nowhere to put an intercooler. Without one the air into the engine will be so hot you'll loose all the power gained by the turbo. norman verona 1989 BDR Link to comment Share on other sites More sharing options...
normalbloke.29 Posted October 13, 2003 Share Posted October 13, 2003 I have a YB Cosworth powered Caterham. You are right in your comments about it being heavier than the superlights etc, and it's not everyones cup of tea!It also upsets the purists which i find amusing.It won't ever be the fastest thing around a track, but i thought long and hard before I bought it. Do I want to break lap rcords or just have fun in it. The latter came to mind.As a road car it's a different kettle of fish.It's as docile as you want it to be, and it'll pull cleanly from 1000 rpm in 5th, alll the way to a genuine 145, without a hiccup.It has well over 260 ft/lb of torque, and will be as mad as you want it to be.Overtaking is totally effortless, more so than any other Caterham I have driven.But it's best quality is tha fact that this engine, even in this state of tune it is relatively bullet proof. Anyway, enough of the wind, it's currently off the road, and wil be back next year with closer to 400 bhp.You can never have too much power, you can always choose no to use it.IMHO!

edmandsd Posted October 13, 2003 Share Posted October 13, 2003 I'd bet that HTR's just built SV will be quicker than the V8 bike one in a stright line...........at least for a little while Home of BDR700 Link to comment Share on other sites More sharing options...
Graham Perry Posted October 13, 2003 Share Posted October 13, 2003 You can insert an intercooler the same size as the radiator in front of it. Admittedly it won't be as large as some but it would probably be enough. Link to comment Share on other sites More sharing options...
edmandsd Posted October 13, 2003 Share Posted October 13, 2003 Good ways of getting 300bhp in a Caterham: Hart420R BMW F2 V8 bike engine if you're happy being a guinea pig Bad ways of getting 300bhp in a Caterham: Hyabusa turbo - they don't give this power anyway. Any 4 cylinder turbo for that matter Two bike engines I was going to go the turbo route but with a purpose built v.high compression BDT engine on methanol as this would sort out the inherant problems associated with turbo engines/turbo engines fitted to Caterhams. It probably would have given closer to 600 bhp and not 300 bhp though which would have made it totally impossible to drive. normalbloke.29 - Take you're engine to Aaron Tucker at HTR and get him to build you one like the one in the Cossy at Brighton which did 134 mph through the speed trap. Fitted to a Caterham you should top 140 mph trap speed...............on your roof in about 14 seconds ! Home of BDR700 Link to comment Share on other sites More sharing options...

Chris G Posted October 13, 2003 Share Posted October 13, 2003 The holeshot turbo option is absolutely manic and suits the car down to the ground. It's not a cheap way to go but it's still an awfully good car. Turbos really aren't all bad. I've got a cosworth engine in my se7en. Puts out about 330BHP and about 330lbft. It's not be the purists cup of tea but IMO it's just fabulous. Turbos take more driving to get the best out of them but in a light car like the se7en they're a lot more friendly than in a lardy sierra. The big thing to learn is that you don't welly it in second, or third if the tyres are cold, or forth if it's wet. Once you've learnt that lesson they're a pleasure to drive. Costs involved for that power could be as little as 2500 quid but I spent rather more than that because I'm a bit of a tart for shiny bits. 380 BHP is achievable without internal modifications and a reliable 440BHP is achievable with cams/injectors/turbo/chip and a skim to lower compression. Cost to go to that spec is about 4 grand. As an alternative an LS1 or LS6 install is very viable in an SV once you've beefed up the chassis. That gives you 350BHP off the shelf for about 3 grand, 500BHP for 5 grand. So arnie, what's your route and HTF did you manage to spend 15 grand on the install? Any of the routes above you could have had >400BHP and had more than 10k left in the bank. Link to comment Share on other sites More sharing options...
