RV8 aspiration - A question

[YRRunner]

What carb set-ups are you chaps with RV8's running please? Many thanks.

[ctsdave]

We've got dellhorto 48's on ours, works very well!

[Guillotine]

yup, quad dellortos here too, and Tims. That was the original format for RV8s.
Think Darrens has efi and Grahams has Throttle bodies.

48mm

Mine has Lucas 14cux Efi,fitted to comply with CSCC Future Classics regs - which have since changed - all somewhat academic as were racing in DTEC instead.
There have been a few occasions where i've been on the verge of binning it and fitting carbs, but we're sticking with it.
In fact we're at Oulton tommorow to give it a run, hopefully reliability wont be an issue... Fingers are crossed .

Andy, when you say Tim's if you mean my old car then that's running on throttle bodies too (Jenveys)

[Guillotine]

Ahh yes,

That'll be the 5.2L eales special on throttle bodies with trick headers. (not to mention big brakes and Ohlins)
Rated the same as an original TVR 4.5l on carbs....

Still beat it though



Have I mentioned that before????

Yawnnnnnnnnnnnnnnnnnnnnnnnnnnnnn.

Fastest laps at bh and donny . . . ????? & with only 320/320 dyno'd a.t.f.

N.B. Need to pick up those wheels sometime Andy

Wheels...no problem dude, taken the tyres off already.
Fastest laps...go will the power.

wins against faster cars.... now that takes some doing


275 at the wheels....
Ealesy said there was nothing wrong with that engine, in fact it was very good IIRC, light refresh and back with 380? +55bhp on a light refresh, no wonder he's the RV8 God.
When he rebuilt my 5L it only gaineed 15bhp. Maybe I was done...or your graphs toilet paper.

I can have another graph for your for Tims engine by Monday btw, RR'd with 220bhp if you want.

[NTEL]

I've got quad 48mm DRLA Dellortos on mine too



Andy, I think you've got your numbers mixed up matey...... Tims is running at 367 bhp.....Mine, however, has got 378bhp ..... I suspect you have something similar if the truth were known

Perry, my carb linkages were the same as yours and were really naff and over complicated. JE fitted his linkages whilst the engine was being rebuilt and it is really worth while upgrade. 100% more positive, simple and accurate. All the butterflies now open at the same time and to the same angle

[spitfire4v8]

In amongst all the light hearted but element of truth bickering have you guys decided on the regs for this year yet? any idea when they'll be available to view ?

[Graham]

48 jenveys on mine..

oh and 400bhp at the front wheels, never mind the rear

Don't think they have been fully sorted yet J. Should be sometime in March I think.

Anybody know why the rockers below are different to the TVR ones on Dave's pic? Can't read what the plaque says.
