Rolling Road thread! NOW WITH PRELIMINARY RESULTS!!!

[Wilson325i]

In reverse order of bhp: engine/bhp/torque (excuse in brackets):

Adam 2.8/203.7/206
Jimbob 2.7/200.4/194
PeteE30Tourer 2.5/178/186
Johns325ise 2.5/172/180
6potwill6pot 2.5/171/180 (absolutely stock!!)
TouringDaddy 2.5/163/160 (chip problems)
Simon13 2.5/162/170 (disappointed)
DaveTouring 1.6Civic/161.5/114 (incredible!!)
Fowler 2.0/109.6/115 (worn cam)
Jonbouoy 1.8/109.2/123 (running very rich)

nice figures i should have shown up for this, and see wht my sport does:( . anyway

(this does not have to be done) but i think we should use this oppotunity to test out these rolling roads, fresh from one RR to another RR!!!! (to quash the myth of the RR's)

SAL/ M5pilot?? is there anyway you can borrow karan/6potwill6pot's touring? the one highlighted in red? it seems to have the standard modes you would easly find on a 325i!! K+N and a Scorpion back box

then take it to bexley's and see if it performs well, the way it did??:D (i repeat just for the hell of it)
i should have used my car for this test since am taking it to bexley's for a power run, but i kinda overlooked this dyno session (sp)

yeh he could borrow my beast i guess.......... if im not using it or drifting it

its not 100% reliable yet as gotta sort cooling system and get her MotD

[Chaos]

I was dissapointed as i thought it would make stock as it drives so well. Nevermind back to the drawing board...........................

yeah but it has pretty much made stock hasnt it.
Ant said that phase 2 cars stock power is not 171 and hes the man who wud know.

[Simon13]

it would do 190bhp at bexleys!!!

[Richy325iTouring]

nemo would have done 210 then lololol

[Jimbob]

it would do 190bhp at bexleys!!!

lol imagine what mine would do!

I'm definately going back to surrey for my next rolling road tho, just to keep things accurate

[Karan]

I'm definately going back to surrey for my next rolling road tho, just to keep things accurate

yeh i'll be going to surrey too when my zaust is fixed and i'll be going to Austec racing (tvr race tem and unichoip specialist) for mapping...i have heard they are excellent with unichipp piggyback systems like mine


as for the tourer.... im loving every minutr

i got here MOTable today so she'll be going in soon!! all the stupid things like lights/light adjustment, suspension etc etc.......washer jets.... bla bla bla!!!!!

well happy with the power she put out and i know the plugs and oil are in a very bad way

anyone got more pics from the day... would love to see some e30s on the rollers especially adam and Jims beasts!

[Jimbob]

Got loads of pics, but cuz of the massive fan you can't really see the cars!

[Andy335Touring]

Jim, which cam are you using ?

[Jimbob]

It's got a Dbilas 282/272 in there matey.

[Andy335Touring]

The same one(duration) as Petes ?

[Simon13]

they both have very naughty cams, I now want a 2.7!

[Jimbob]

Pete believes his to be a 284/272 Dbilas cam. However we bought from the same bloke, looking at the guy's auctions right now says 282/272 for the M20, and 284/272 for a Schrick M20. But hey, if Pete says he has a Schrick 284 then he must have.

[Andy335Touring]

I bet you can realy feel when it comes on cam with that jump in torque ?

[Jimbob]

Yea, it's like warp-speed if I'm slowing creeping the revs up to 3300 then floor it

The problem I have tho on my other print-out of bhp/fuel pressure that it soon goes lean, if you have msn mate add my email addy found in my profile and I'll send it over.

Apologies for any confusion caused, but my cam is the Dbilas 282Ԛ°/272Ԛ° for the M20 engine. No idea where i got the 284 from.

I'm going to get those pics sort out now.

[Andy335Touring]

Sorry i don't use MSN mate.

It would be interesting to see what a mapperble ECU could do for your car ?

[Jimbob]

Pete I checked the Dbilas website and there is a 284 cam
Also found some rather nice throttle bodies on there too

I neeeed mapping!!

[PeteE30Tourer]

For all those interested, i've posted some photos here:

[Davenotouring]

Is he still going to mail the graphs to you Pete?

The jump in power/torque when the VTEC cuts in is quite amusing.

[E30Adam]

I hope he does, I'd like an electronic format.

THe sound was pretty awesome when it kicked in too Dave!

[Davenotouring]

Yeah, it is quite mad.

Should have taken you for a spin in it really.

[E30Adam]

Yeah, it is quite mad.

Theres always next time!

[Davenotouring]

This is true, but the touring will be ready soon.

The Civic may be being withdrawn from road use!



Nevermind!

[rare]

Some impressive stuff , especially your results Jim

But dave..come on...Decommissioning the civic?! WHAT IS THIS?!

[Davenotouring]

Decommisioning for use on track, and Santa pod!

Can't really afford to tax/mot/insure three cars!



Not worth selling it!

[PeteE30Tourer]

Is he still going to mail the graphs to you Pete?

I hope so. I wrote to him yesterday as follows:

Hi Charlie,

Just wanted to extend my thanks in writing to you and your colleague for hosting our rolling road day yesterday. I think I can speak on behalf of all those who attended in remarking that we really enjoyed the event and were impressed both by your facility and the expertise and advice you had to offer. All the results have already been posted up on our forum, which has started the usual round of interesting debates and comments.

As discussed, if you can get me all the graphs electronically, I'll compile these along with the details of the cars tested and the photos taken on the day, along with a few words about the day to send to Performance BMW magazine in the hope they'll do an article for us.

Regards

Peter


Haven't heard back from him yet, but he did say it would take a few days as he has to transfer them all to floppies to move them to his home PC before he can email them. Once i have them, i'll email them out to everyone.

Final note on the potential Performance BMW Magazine article:
Can everyone who put their car on the rollers please provide me with a quote or two on the day's events. This could be your views on your car's performance, on the day itself, what you thought about Surrey Rolling Road, on how wonderful the zone is etc. Just need to collate some interesting stuff to add to the photos, graphs etc.

Thanks.

Adam's car in its current state made 203bhp (or there abouts) on Bexleys rollers.

Therefore Bexleys rollers actually read slightly lower.

So Simon13's car would probably make around 150 bhp on the Bexley rollers!!.....

[M5pilot]

ive had the pleasure of being in 2 stock c2s and i have to say Jims car is faster

Yet again Karan fails to remember that Jim's car had a 4.10 diff in it when he was a passenger and C2's come with a 3.64 diff. Of course the C2's are going to be slower!

There's hardly any different in the spec of a C2 engine vs the custom built ones other than the steel crank.

My C2 hit 200 bhp and 200 lb.ft with its 268 cam.

[E30Adam]

Adam's car in its current state made 203bhp (or there abouts) on Bexleys rollers.

201bhp but this was with 4bar fuel pressure. My car was chronically overfuelling after the remap, it stunk and subsequent tests on a SUN gas analyser revealed that the emissions were far beyond acceptable MOT levels so I had to reduce the fuel pressure to 3.5bar and the car feels like it's performing better. I've alsu built a heat shield around the cone filter since Bexleys rolling road session.

3bhp difference between rollers is nothing. It's barely even measuable because the difference could have been affected by temperature or anything.

3bhp on the road would make no difference in a head to head race of cars with 3 bhp between them.

[E30BeemerLad]

Dave, if you're gonna turn the Vtec beast into a strip slaag then consider building yourself a wheelie bar that is in constant contact with the ground. I've seen them doing it in the states on Civics that are running in the 9's. Just helps the inherant problem of getting a FWD car off the line with the effect of weight transfer and no grip

Make sure you take this up with Bexleys.

Basically the rollers are about the same then.

C2's come with whatever the diff the base car had standard in LSD form

[Simon13]

i've put my standard chip back in.......................

[Karan]

It takes massive amounts of extra power to out accelerate another car. 20 bhp just isnt going to allow you to dissapear into the horizon. You need more like 40+ bhp to make a real difference on the road.

This is pretty much true!

I don't know about 40+ bhp, but probably 20+bhp. Relatively normal cars can keep up with faster ones if really caned!

Thats true, the Tourer slag pulls away from the Puma but only slowly

What are you going on about 'slowly' I was shifting up at 5.5k.
