Burpspeed Version 2: Race Car Build

[Toastfrenzy]

Looking good, about 15-17 bhp up on last year? Wish mine was up and running, Dan's got man flu.

As you're not telling why the 95 RON I just have to ask.....Why?

 

[Tony Hunter]

Because we get it ALOT cheaper.

 

[Jay Payne]

car dyno'd around 190 last year so well up on what we had.

Fuel wise........ just coz. petrol is petrol. as long as its mapped to what we want to use. 95 Ron is everywhere. super vairies from place to place. some is 97,98 or 99. plus if its hanging around and not fresh out the pump it degrades and you end up with lower octane anyway

Tony/Jay, Im back in the UK on Monday, will pm you ref this season I should be at brands and silverstone

 

[Jay Payne]

ok mate cheers

 

[Matt@codered]

What? Do what to it?

PM me your email and I'll send a photo, I'm not a full member yet so can't attach photos here.

Basically the walls of the chamber in the head were machined to the gasket line and got rid of some valve shrouding, this improved flow.

Pic on its way with flow result.

We are quite pleased how neat the fuel lines came out, the 180′ bend was quite expensive but makes a very tidy job of it.

lol, yes, the price rise from a 90deg to a 180deg is quite a jump... in applications like that though nothing else will do.. does look the part!


excellent result on Matts dyno..

 

[Nafoff]

Come on Neil keep up.
We were meant to video it, but got carried away having a tidy up and missed it.

i knew only scanning your write up would bite me in the ass....

 

[JackJack]

Nice update! There's a picture of it in PFC magazine when it was at tdf.

 

[bomber]

Happy days, bet you're both well chuffed

 

[Jay Payne]

very happy yes. will be even more so after our next visit.


Engine spec for skimmers:

-Stock 182 bottom end
-ARP Rod bolts
-Phase 1 head
-cat 421 cams
-AT bodies
-95RON Fuel

lots of little bits for reliability in it like the supertech valves. should be a nice lump this

 

[Nafoff]

Something I've done before on a number of engines, but that level of detail I usually leave for a high compression, eek every drop of power build, which this wasn't. The brief was some more power, and reliability as the primary targets. Pretty pleased with the results

 

[Jay Payne]

im particularly pleased with the torque figure.
and
it sounds mental

Ah ha ,he lives.

 

[Tony Hunter]

I must admit, it does sound fkn mint, crisp and responsive.

Not sure about noise level now

posting the first start/running vids?

 

[Jay Payne]

no they abit pants. will wait till have some dyno noisy ones

 

[Dan519]

yeah, just watched them again. Think we got a bit excited and forgot to bother recording properly LOL

 

[Jay Payne]

bit like us yesterday. all i got was tony about to drive back on the trailer

Agreed, most 16v engines benefit from this sort of thing.
If the brief is what you have achieved, brilliant stuff!

 

[Dan519]

not surprising as you'd not eaten all day. No toasting bread left FTL

 

[Jonny1*2]

Great results guys. What has Matt set the limiter at? Out of curiosity, what's the retail on the supertech valves?

 

[Jay Payne]

not sure what the limiter is tbh. will find out.

Dan will answer about the valves im sure. I know they took a long time to arrive, like months

 

[Jonny1*2]

They are from the States yes? Long time though

I love the way 421s make the engine scream on full chat will be interested to see how the torque delivery looks.

 

[Dan519]

Retail on the valves is "about" £400 after shipping and import duty is accounted for, depending on the current exchange rate

Not bad at all tbh. I'm over there in a few month. If I get chance to find some I'll have to smuggle them back

 

[Jay Payne]

doubt you will find any. Renault dont sell cars in US so prob no stock anywhere

 

[Dan519]

they're made to order AFAIK

 

[joshhicky]

Looking ace guys keep it up cant wait to see it fully finished

 

[Silent_Scone]

Look forward to hearing this thing screaming its nuts off at Brands

 

[Tony Hunter]

The valves were carefully shipped over, protected between the thighs of Virgins, whilst being serenaded by Angles with Harps.

 

[Jonny1*2]

^^ been drinking mate? That's so random.lol

 

[Tony Hunter]

No, thats why they cost so much.

 

[Jonny1*2]

Arrive pre lubed

 

[Tony Hunter]

Smelt nice anyway.

 

[Dan519]

Arrive pre lubed

Nothing that can't be improved with spitting

 

[Tony Hunter]

On that note, I'm off to bed.

Goodnight.

Dan, thanks for the toast and Marmite.
