I have 1700 crossflow tuned to about 136 bhp.   Having trouble with too much noise!  ie about 98 dba static test.

Can someone advise me how I can get the noise level down, ideally I would like under 90 dba for Thruxton, but any reduction would be a help. It has the standard side exit exhaust.  

Many thanks for any help,

Russ

Thanks Guys,       Your expertise and your willingness to help, re  advice on tyres,  are much appreciated.       Russ

I have a 7 Supersprint with approx 140 bhp at the flywheel.  (tuned 1700 crossflow).

At present it has standard road tyres, Uniroyal Rain Expert, which are 185/60/R14.

Could someone recommend  suitable tyres for track days and sprinting.

Many Thanks,

Russ

Can someone advise me on which tyres are best for track days and or race?   Need to be road legal. For a Supersprint with approx 140bhp and 14 in wheels......Thanks, Russ

Planning to do track days....7 club one at Castle Combe etc.....What measure of decibels should I expect from a Supersprint with a crossflow engine tuned by Vulcan to 140bhp?    I plan to get it measured at Thruxton on 5 March, but anticipate problems...I think I'll be asking for advice on how to make it quieter....will let you know.

Hi All,

 I have a Ford 1600 x flow, wet sump.  

  Where do I get an Apollo tank,  and would it be straightforward to fit by my local garage engineer?     'scuse my ignorance.

I also need tyres for 14 in wheels.  Looking at the MSA Lists 1 a and 1b,  (so I could do Gurston Hillclimb events, and maybe Castle Combe Sprints).

Thinking that R888r's are a bit extreme dry,  Would appreciate advice.   

Russ P

Still needing advice...    Does anyone have knowledge re suitability for trackday hillclimb,  of:    Continental Prem contact 5,   or

Vredestein Sportrac 5?   As they are available in 14 in

Many thanks for all that info, Richard.

Russ

Thanks Richard.   It is De dion ..Thanks for tip re Minators.  Next questions...sorry about this...what size wheels if go for 13inch, and what profile tyres?

Russ P

So next decision, may be to take Mike's advice and go for 13in wheels with ZZS's ...so which wheels?   Minilites?

Hi Mike,    

  Thanks for pointing that out....my mistake,,again!    I was reading 11.9.1.5,  when in fact 11.6.2 actually applies..as you said.  I'm pleased I asked the question.

Will try for Avon  ZZS,   as you recommended,   hopefully available in 185/60/14

Thanks again,

Russ

But thanks for the useful info anyway.

Hi All,

   I am a new member, with some racing experience, and have just bought my first Seven, a  Series 3 with a 124 bhp crossflow motor.  

I need to change the tyres for a set in the  MSA List 1, (to comply with hillclimb and sprint regs, ) for the 

Specialist Production Class.    Can someone give me advice as to which tyres I should buy, to best suit the car, please?

Many Thanks,

Russ P
