Robzki Posted February 28, 2012 Share Posted February 28, 2012 Hi all Just got a quote from Competition car insurance and as a lot will know they need the horsepower as that is what it is rated on. The supra is a jspec tt basic bpu, at the moment it doesn't have a RR but does have a race cat which seems to do the same job at keeping me at 1 bar. I forgot to ask whether they rate rwhp or fwhp as that would change things. I don't have access to a dyno What would be a rough guide of my hp for at the wheel and at the fly, I know it is a difficult question to answer but at 380hp they quoted £459, if I up it to 400hp it goes up to £569. I need to sort the insurance today and although they gave a fairly good quote I don't want to underestimate the hp but on the other hand there is no point in overstating it. Thanks for any help Rob I'm not sure how they would check my hp if anything happened and guess that they would just check the mods and then look at the forums to get a guide, so that is what I'm doing Link to comment Share on other sites More sharing options...
Westy Posted February 28, 2012 Share Posted February 28, 2012 I'm sure the car would dyno under 400 bhp anyway on BPU if you aren't making 1.2 bar boost! I would say 380-390bhp would be about correct. Link to comment Share on other sites More sharing options...
Robzki Posted February 28, 2012 Author Share Posted February 28, 2012 hmm, I'm not sure what they rate the bhp as, either fwhp or rwhp, I'll give them a ring and check. Looks like I may have to go up to the next level of cover, I'm pretty sure that with the age/mileage of the car that it wouldn't hit over 380 but I guess its better to be safe than sorry.

mwilkinson Posted February 28, 2012 Share Posted February 28, 2012 Plenty of J Spec BPU cars make 400-410 at 1.1-1.2 bar at the flywheel. If I were you I would go for a figure of 400-410 thus giving you some head room. Link to comment Share on other sites More sharing options...
Robzki Posted February 28, 2012 Author Share Posted February 28, 2012 Guess I'd better give them a ring I would rather err on the side of caution but don't want to waste money. They didn't tell me how they wanted the hp worked out so looks to be a grey area, as I doubt 350 at the wheels would be possible in an auto bpu. unless I understand how we work it out. Glad I'm not in the Usa as mine would be 750hp and would be very expensive Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted February 28, 2012 Share Posted February 28, 2012 I would say 380BHP IMO the "genuine" 400 BHP BPU is a bit of a tall one anyway, and in any case how are they going to prove anything, there is also the fact that BHP will vary with the air temperature, winter to summer.

stevie_b Posted February 28, 2012 Share Posted February 28, 2012 I think it would be OK to estimate it at just under 400bhp (but you'd probably need to check the rwhp or fwhp query). As tericky-ricky said it's notoriously difficult to measure accurately, and you're doing your best to do so. It's people estimating their BPU TT car as 300bhp that they'd have an issue with.

Robzki Posted February 28, 2012 Author Share Posted February 28, 2012 (edited) LOL, thanks for the advice, its 20% more added to the premium to go from 380-400hp although that may well put me in the next bracket which could be 400-500hp I'll give them a ring and clarify whether its at the wheel hp and how they bracket the hp I guess they will use these forums as a reference. If everyone could underestimate their bhp over the coming months it would save me a lot of money.

You'd be less than 400 then Link to comment Share on other sites More sharing options...
Westy Posted February 28, 2012 Share Posted February 28, 2012 Their brackets are under 400bhp; 400-600bhp and so on... Link to comment Share on other sites More sharing options...
Robzki Posted February 28, 2012 Author Share Posted February 28, 2012 Their brackets are under 400bhp; 400-600bhp and so on... Oh, So I'm better off saying 599hp which will give me room to add a boost controller Link to comment Share on other sites More sharing options...

You'd be less than 400 then I do scare easily, I also get hurt easily and your wit has just cut me deep. ......... Link to comment Share on other sites More sharing options...
Havard Posted February 28, 2012 Share Posted February 28, 2012 I would tell them you estimate it at 380 and let them worry about it. It's not as if they can dyno it after it's been stolen or binned..!! A dedicated forum to the marque can't agree on the BHP figure so the insurance has no chance. H.

Aww, sorry man Well, I'd say less than 400 if it were me as there's no proof that you ever run the boost at 1.2bar. Link to comment Share on other sites More sharing options...

No boost controller anyway at the moment. so should be easily sub 400. Link to comment Share on other sites More sharing options...

Josh Posted February 28, 2012 Share Posted February 28, 2012 Nope, they just want me to tell them what the hp is. Well mine at 0.9bar made 356bhp at Dynodaze so if you have a boost gauge, you could try and work it out Link to comment Share on other sites More sharing options...
Havard Posted February 28, 2012 Share Posted February 28, 2012 Nope, they just want me to tell them what the hp is. And you are considering exaggerating your HP so they can bill you more? If we were in the pub it would be over 400. Insurance is 380. This is a no brainer mate..!! Link to comment Share on other sites More sharing options...
J_Supra_07 Posted February 28, 2012 Share Posted February 28, 2012 Threads like this could see guys in pubs talking down their BHP figures. I have 100hp at the wheel, thatll be £300 :-) lol Link to comment Share on other sites More sharing options...
