Following on from the "ultimate rs" thread, how many are there over 300bhp?And what sort of times do they run?I read the aticle on SOY in perf ford, what a weapon, that has some mental power!

there are a few, tim's old one, Ollie's that I know of. Obviously sunny too.

There are others out there but I don't think they are finished. I think C&B are going to be knocking on the door of that sort of figure.

Soys looked good. Thing I never understood (reading his feature) was why the power stopped at 5000rpm. I think it said didn't get around to finishing it, not sure exactly why. Anyone know? Looked to be awesome when done 8500rpm limit!

Yours could be, set of steel rods and some more boost and your there.

 

but how many are there with RST CVH power over 300bhp.

300bhp out of a 16valve zetec 2.1 is not that difficult.

cheers

 

Shing's (Tims old car) Is a CVH 1.6 running more than 300bhp, built by Norris Motorsport

 

was norris not building a 1.6cvh with closely to 400bhp

cheers

 

im hearing enough good things about norris motorsport

 

You mean this one

Taken from Karls web site www.norrismotorsport.co.uk

Power:
Expected 400bhp
Engine Spec:
1600cvh, NMS Steel crankshaft, NMS Titanium con-rods, NMS Forged pistons, NMS Stage 5 Cylinder Head, NMS Tubular exhaust manifold, NMS inlet manifold, NMS solid lifter cam profile, GT30 Garrett turbocharger, 42mm Racegate external wastgate, 3.5" custom exhaust with 2.25" wastgate screamer exhaust, Weber engine managment, 8500rpm limit.

 

yes this one. how far is he with it.

400bhp out of a cvh 1.6 is very difficult.

cheers

 

People said 350bhp out of a 1.6 cvh was impossible a few years ago

Times change, it is a work in progress

 

How much?

 

the only problem you have with a rst cvh engine is that the crank/rods/ piston arent up to the job.

it must be all steel and forged.and that is really expensive

cheers

 

"NMS Steel crankshaft, NMS Titanium con-rods, NMS Forged pistons"

 

Ours is nearly finished, its just a case of having time for the few bits and pieces that remain. Not sure on Power, but we're well up towards the limit of the 803's.

As for Karls 400bhp 1600CVH, with all respect to Karl as his work is very good, I can't imagine a 1600CVH spinning up a GT30 effectively enough to produce anything other than raw top end power. I guess I will be made to eat my words and hope I do. Big respect if he does it!!

 

Well he has got a 1.8 Pinto to spin up a GT42

 

 

what would the point be in a 300+ bhp erst if it had no torque?don't know what the figures are like but i cant imagine theyre too great.IMO id rather have bags of torque for enough acceleration to re-arrange your insides than be able to go down the pub an say my escorts got 300 bhp because other than a track theres getting fewer places you can go over 90mph without being raped by the old bill all my own opinion though before anyone gets upset
cheers kris

 

huge torque spikes are good for what?

Pointless Wheelspin?
Breaking Gearboxes?

Smooth drivable power that you can actually put down is the way forward. Anyway who says it's going to have no torque???

 

Mr C,

It is a problem when you only have 1600cc's getting the turbo to spool early, BUT what I do is simply extend the rev range.

rather than having a 3500 - 7000rpm power band like my T34 1600's have, the GT30 equipped engine simply moves the power up 4500 - 8000rpm.

Its all about the cylinder head in making power! 400bhp from a cvh is straight forward once the engine strength is sorted. I personally reckon 500bhp is easily achievable, though I don't fancy the engine lasting that long or indeed the bill the customer has to pay!!! ROFLOL

 

Cool. Get on with it then!! Would be totally awesome. I would imagine that you will need the strength of Arnie to hold it on the road when it makes boost a 4.5k!!

Is it SERIOUSLY on the cards??

 

i didnt say shit about spikes.and by no torque i mean not a lot as its a 1.6

 

OK, so the torque aint great, but they do rev nicely.......

 

With FWD, the secret is a broad power band with a flat torque curve, The 1600 lends itself perfectly to this as the 8v head is a good match for a high revving 1600.

 

im sure christians aint far off 300 bhp with the spec

thats another nice car to watch too

as for karls 1600's , lots of top work thats changed the way people look, but i remember christans car first for some reason , not sure why though ( as in i remember hearing christian had big bhp before i heard of shings car)

oh and ollies car is fooking rapid on the track, really really quick i wanna know what bhp that is as its a fooking nice motor

 

ollies is currently running around 330bhp though we have mapped it up to 360bhp. More mods shall seen more power over the next few months!

 

seen it at national day what a fooking animal

 

My car is currently having more mods lol

That 400 engine is for CHadley but he's about as much use as a chocolate piston.

Aint u 'arris.

OK, lets cut to the chase, any RSTs been PROVEN to produce 300+ (sorry if this an easy question, ive never looked)

Kris- Somthing tells me you either not really understand power/torque or never driven a big power car with limited grip, if you want tons of torque...

 

I must admit, I do quite enjoy a generous helping of good old horsepower, but I seriously wouldn't go much further than I have now. There is only so far I would go in terms of throwing money at an RST.

I bet that 400bhp engine would cost £1000's!!

 

Gotta agree with C+B
I didn't have a hand in specing or building Tim's engine, I just brought the car.

But fook me I am finding out about the costs now...

I would hate to properly fuck one up... yuk...

J

 

hence why i sold my engine

 

The bottom line for me is this......

At virtually 30 years old, I must be one of the oldest RST onwers on here, since Tim sold his (DaveEscos - Eat you heart out!!). I aren't messing around with an RST because I can't afford anything else. I actually really enjoy the whole Torque Steer/Wheelspin/Harshness thing that my RST provides. However, there would have to come a time when I stand back and take a look at the whole situation and then sell up and buy an Evo. Thats not on the cards for me, but it would be before I spent any more large sums of money on the RST.

 

C+B Another well put point..

I dont have an RST (contary to the belief of some) because I cant afford owt else I can afford lots more expensive cars but I choose to stay with what I like

I enjoy driving it and feel safer in a FWD car... its what I have grown up on and live with.

Marco and I had a chat about this once, he grew up with Mk2's etc and cant stand to drive a FWD car quickly as he feels unsure... Where as I am the same in a RWD car.

 

well i drive like a girl in any car and find that i was about to spend way too much fpr a car i can even have the baby in

never knew ya was 30 christian , i always thought i was older for some reason ?

 

PMSL. I always say 'You're as old as the girl you'd like to feel'. Beccy would say that makes me 16.

 

Mine will hopefully be knocking on the door of 300bhp by next year

Should be sorting the rods and pistons over the winter for a new bottom end build about spring 05'

I'm a 28 year old RST owner and I have it because I like it Yes I could get a Cossie if I really wanted but the repair costs put me off and seeing as I can chase a lot of Cossie's once rolling anyway why would I want to change to a car I'll have to mod to break even with what I've already got?

 

Aaah, babyface Chris You dont look 30 mind

LOL Spot on

Gary Gitters around 5 years old by the way

 

steve you break ya erst more times than switch breaks his cossie

oh and ill let ya take the saff for a spin mate

 

300bhp would be nice round figure to achive.....
but an Escort Cossie would be nicer imo so I have no intention of breaking the 300 barrier Even with my current spec I'm probably still at least another £2k off and i'd rather put that in the cossie saving pot.

276bhp is close enough for me

 

why shouldn't 4 or 500 hp be possible? don't forget the 1.5 litre turbo's with well over 1000.

i was watching some tv programme on them the other night about the bmw ones, and they reckoned they used ones that had previously done over 100,000 km on the road before being used in f1. they reckoned that by then all the stresses of the casting process would've worked out and if it wasn't broke by then, it never would. they also reckoned that they used to leave them out in the rain behind the engineering block, and that sometimes the engineers would go outside and piss on them (best thing for bmw's if you ask me).

as karl says, it's just about the money to get a strong enough bottom end, and getting the head to flow enough.

 

Im confused there, as i thought none of the engines were based on any road car engines

I thought they were the Monoblock BMW Megatron engines

Unless the early ones were based on the 4cyl block which is the base for the E30 M3s, 2002 Turbos, etc etc, i know them engines were turbod to 700+ and destroked to 1.5litre in some race series (vs the Zakspeed Turbo Capris etc) but didnt think they were ever used in F1
