New R5 GTT 1/4m record today !

[Scoff]

He's finally done it, Glenn HI5 with his EFI'd 1397cc C1J engine ran an 11.40 @ 124mph today at Santa pod knocking Stuart Clark off the top UK C1J spot.

He did 16 runs at full power, full throttle shifting on slicks without a single failure !

Hopefully he's got some vids of todays action, big well done mate, ready for phase 2 ? ;)

Leader board to be updated with info shortly.

[Markey Mark (BD)]

:agree: Thats some good going there, good to see it back pulling the good times now after the few mishaps thats happened recently.

Well done Glen. :)

[Hi 5]

the time not the most impressive thing its good but if you had seen the stick it had 16 flat out runs and the slowest run was a 121mph and not 1 problem all day :yeah:a big thanks to the mad sceintist looks like have only 1 more person to beat now so best pull my finger out stage 2 in progress :scared: lol

ps thanks for the good comment

[Rob@Backyardracing]

it is a fantastic performance mate, anyone who knows once you crack 120mph in a c1j, finding anymore is extremely difficult, with, or without gas, as i believe stuart clarke also found out, (added gas and dont think he went any quicker?)

not too mention your short track must be spot on :)


chop chop with the incrementals.....

fantastic work well done :agree:

[Stuart Clark]

Well done, great result.:)
I would love to see someone else have a go with my old car.
My last run out was 29th May 2009 and best time was 11.55 but my main frustration was stringing it all together, launch, NOS, etc as my terminal speed was 127 and the 1/8 was 7.55 at 102. This varied but generally was 125 and 11.5 to 11.8. After bending 2 rods and lack of time I gave up the mantle.
This makes me want to start all over again........;)
Good luck with chasing the tens!!!
All the best
Stu :agree:

was stu clarks r5 gt record with carb and without NOS?? if it is thats well impressive on a carb!! well done for the record hi5

[WADDIE]

Well done Glen. :) :agree:

[Scoff]

Yes, I think Stu will always be the king of the carb-fed setup and to this day I think it's utterly astonishing what he was able to do.

I think with Glenn's motor we've found the limit of what a standard piper 285 and cylinder head can do. I saved my old C1J drag cam for a rainy day when I threw the rest of my engine away 5 years ago so that might find it's way into glenn's block along with an improved cylinder head. It would be fantastic to challange Gianni's time next year.

[Andrew Cooke]

I still think a nitrous motor without the turbo would work better, you could run better cams and a decent exhaust manifold without having to worry too much about reversion, intercoolers etc. Admittedly it'd be a bit pants without gas :D

An R5 GT with a Turbo ? :D

In my mind atleast it's anyone who retains a C block and cylinder head - the heart of the original car I think. Glenn wants to stay true to the scene and keep it C1J, and hats off for that, unlike some other rougues who cheat with 16v things :innocent: :p

[Mart]

:D :cool:

[jonnyshaw49]

i think its astonishing what you guys scoff, glen and stu have done with the renault 5 engines, and it will be rememberd in history lol and make my restoration worth more in the future :D well done guys, and if your ever up north pop into mine and sort mine out!!

[Matt Cole]

Scoff, that drag cam of yours, how does it compare to the crazy cam that DD produced sometime back, which i think Briggsy still owns??

[Scoff]

I think the DD would be a bit lairy for a big-boosted or nitrous C1J. It looks to have quite a lot more overlap than mine.

lots and lots:):laugh::laugh::laugh::laugh::laugh:

about 130hp's worth if you believe the numbers. it's programmable though, so there's a different amount in different gears :)

[clee]

Devils advocate here , what are peoples views on gas usage and the 1/4 mile leader board rankings seeing as we have 0.01 splitting the top 2 RTOC boys .One on gas , one not .
Discuss :coffee:

[Scoff]

everyone will have a different opinion on this one, it would make for a good debate :cool:

My 2p, and the way I see it is that if you want to go much faster than that sort of time you WILL need nitrous.

It's possible to build a non nitrous motor like Stu did and make that time as Stu has proven. That is really impressive. I think even with the EFI we'd have been hard pressed to do what Stu did.

But, as I'm sure Stu will tell you, it is almost imposible to make any more power than that though. With glenn's from the off it was always going to be a nitrous motor, with a goal of going much quicker than 11.4, so everyhing about it was put in place to make the best use of nitrous and in larger doses than it has now. With nitrous it shouldn't be too hard to go quite a bit faster still, to get up there with gianni. If we had built a high performance non nitrous motor then we'd be tearing the engine to bits right about now wishing we'd have built a nitrous motor from the start. It's all part of the master plan *lol*

it's all good fun which ever way you go, and none of it should be taken too seriously :)

What are the main differences as far as engine build goes ? Does it work better on a particular design or layout ? Would a lazy old V6 respond well ?

[Hi 5]

there's not loads of changes but as far as nos on yours son depends just how far you have tuned yours ie how much to the limit it is but any motor out there will accept 50 bhp of gas but mine was built with 300 bhp of gas inmind so a little more thought was required in how to get the nos out. getting it in no problem:)
yours would respond really well to nos as the bmw 8 series in the video is running 150 bhp of nos and the chap was loving it

nitrous changes a lot of things! essentially there is a lot more exhaust gas to deal with so exhaust valves, exhaust ports, turbine sizing and wastegate all need thinking about. compression ratio gets a lot more critical too. it's really hard to put a lot of gas into a motor with a c/r that is too high without having to overly compromise on ignition timing, which directly effects EGT and the likelyhood of other nasty stuff happening in the chamber. Like most tuning though you can only guess the starting points, it's down to trial and error in the end. Like recently we discovered that glenn's motor responds to more boost better than it responds to more gas. That was a bit un-expected so we just have to roll with it and see what happens.

[Rob@Backyardracing]

Answers one of my questions as I was thinking of nitrous on my engine, I know the comp is fairly high being an MSM build & I had already thought I'd need to use some sort of aftermarket ecu for timing..hmmm, maybe see what it will do off the bottle 1st & then maybe look int oforged pistons & a slightly modded c/r...
All I know is I'm itching to get back to pod :)

[SCHWARTZ]

how do these volvo lumps respond to a bit of nos?:D

lets not get lost with my engine spec as last year i run standard every thing but a gt28 and a 285 cam and 80 bhp of gas and 22psi of boost,on carb standard engine and did 170 drag strip runs no problem

I know it's all in the set up, but having higher comp isn't going to help & I'm wondering if the standard ecu (if you can call it that :wasntme:) will have enough retard when using gas.
It's definatly something I have been looking into & reading up about... I'm trying not to be spoon fed about this but it could end up costly if I don't get a few pointers from people :scared: so am tring to gain as much info as poss.

It wont have enough retard to cope with a high comp MSN... depends how much gas you run tho, i would have thought you want to make big numbers so id sooner start lower comp and work from that base..

Cheers I'll take you up on that, I prob won't run any gas till the spring, I'll see how the car copes 1st without, low 12's is what I'm hoping for without.....

Yeah I thought the high comp would cause probs from what I've read up on Rob... The way I was hoping to get round it was with aftermarket ign ecu bud, you think it's worth a shot ?
I may just see what it does without gas & then lower the comp... I may have to go on a diet to get into the 11's though :D

when you say high comp how high

[Rob@Backyardracing]

OK You see this is where my car was different... My old car ran flat top pistons, and at a guess with 23psi boost i couldnt run much more than 35hp-40hp tops @ 4 deg retard and i was on limit just before det.. 99 ron fuel..

[5teve L]

when you say high comp how high
8.1:1 I think.

[Scoff]

I think the thermodynamics involved with this particular argument are a bit beyond the scope of this thread but in basic terms the no.1 rule is to keep your ignition timing somewhere close to optimal even if it means sacrificing some compression to do it. It's especially important in a highly stressed and compact engine like the c1j where stuff can go wrong quickly if things arn't happy.

steve, if you want to stick with pump octane then you will need to lower that c/r for sure.

[rs250nut]

Put some proper fuel in it:devil:

Yeah, I'm coming round to that idea Chris, I have no idea where to get higher octane fuel anyway..lol.

When James ran the VNT @ 23psi manifold the TDC was fully retarded, he moved it to standard & it popped the gasket right away... I think we can safely say the gas won't help that :crap:
Det-cans at the ready me thinks..

[SCHWARTZ]

can you use that octane booster that you can buy in in a can. is that any good?

[Stuart Clark]

Gas V Boost...
In my opinion, my old motor would have responded to a larger turbine housing if I were to persevere with gas. The extra exhaust volume could not be dealt with (i am guessing a little as didnt test any other housings) and as my gas went straight into the inlet manifold the carb did not further restrict...
I didnt want to increase the housing for a number of reasons but mainly due to gearing as running only 3 gears means you need a large torque band, narrowing the torque band would have meant using 4 gears and due to selections available would mean potentially a non gt box.
My intention was always to stick with the basic set up as Renault intended and for the record it was basically the following.
Std crank, balanced
Std rods, balanced
Forged pistons, similar to standard but with beter oil return, lower skirt, increased squish band but dished not domed.
Std valves on 3 angle seats
Std head, altered chambers and well machined (not huge) ports
Std ex and inlet manifolds
Std carb re-jetted, 27.5mm venturi
different cam with vernier
3 extra engine breathers
std distributer, leads, ecu and ignition timing

i found through years of trying and testing that gains are in the finer detail, cam timing, exhaust housing sizing, temperature control etc

I think given more time, my engine would benefit from gas but that i had found the limits of the gearing and trying to hold the transmission together, I also found that my engine responded better to boost than gas and that maybe my next step should have been a better ignition map/bespoke ECU, oh and steel rods might have helped...
VAG gearbox gives you more options also...

A 10 second C1J, I would love to see!:)
