Rolling roaded at scs stage 2 at 26psi @271bhp still a lot of bhp in a little car especially with no lag

No disrespect but with that turbo on MFI I cannot see how you dont have lag, my guess would be it makes peek boost at approx 4000rpm and very little before 3500rpm?
Dont spose you have a graph so I can see how and where it makes power do you? Would be interesting to see how Harvey has done it if he has!!

thats some impressive figures mate!

cheers mate she certainly performs well just in a dilema now do i upgrade to efi witch would mean changing the rods as well as the other bits ,then will need to look at different gearbox

[Steven_RW]

A .48 housing on a 1600 is quite laggy but I survived with one for years with none of the benefits of the 270 bhp or so that this car has. I only over saw as high as 206 wheels (230 fly or so at a guess) and ran at 195 wheels for ages. You could get boost between 3000 and 4000rpm if u loaded it right up say in 5th. Otherwise it really felt like 4000 rpm before things started happening.

Cheers,
RW

Thats good power your car is makeing must go well mate.

does go extremely well especially after reading about some of the poor figures on the zetec bottom ends

[d4 rst]

Do you now your top speed? Harvey gibbs dos a good job.

[d4 rst]

Efi will make a big power boost on lower psi.

[d4 rst]

Efi is the way

i no that its the series 2 gearing and lsd built into the series 1 casing dont no top speed whenever gearing runs out i presume dont no wether to keep it or not so its hard to warrant spending more money on it really

Ring 01444881949 luke he will give you vgood price and do a vgood job top man:

[Christian and Beccy]

OK, tell me this. Does Harvey still have the same chassis dyno he has had for years? The one where mine made 220 at the wheels, but I later found it to have less than 190 at the engine? Absolutely NO disrespect to Harvey, that man truly knows what he is doing, but that graph looks ridiculous. I may be wrong about his current chassis dyno setup, but looking at the graphs, both the BHP and Torque plots (assuming thats what they are) are on a downward trend halfway across the graph. I'm guessing thats around 4000-4500rpm, based on a comparison with the other graph you posted (243bhp?).

Despite the long list, the only real meat in that spec is the turbo. It looks to have standard rods, standard head and a Stage 3 T3. A T34 with a 0.48 housing will struggle to crack 300bhp on an EFi car, let alone MFi and this is only a T3 we are talking about here.

I'm sorry, but that car is not 270 odd bhp. 220bhp maybe.

hand bags lol

the car came off a lad on here not going to mention names there was 7k put into this as a project and believe me this car has a lot more power than 220bhp

under 1k perhaps? depending on ecu used.

[Chip]

Harvey has a superflo dyno, one of the best in the business, same as most TUV approved places use, and same as mountune have etc.

[d4 rst]

Chip do you now luke?

what is superflo? i thought dyno dynamics was what everyone on here measures there cars by?

[Rob_DOHC]

Luke who worked a bit at auspeed racing (or however you spell it) and now run the other place in crawley?

Or a different luke?

I would love to know how rich this thing has to run at the bottom end to get 270 brake on mfi lol and graph 1 looks so so much nicer.

Rob,

Chip, I'm not talking about his ENGINE dyno, I'm talking about his CHASSIS dyno. I'm pretty sure that your average RST customer doesn't put his engine on the ENGINE dyno.

£7k?? You say that like it's alot of money.

I'd bet money that car wouldn't make over 240bhp on a Dyno Dynamics dyno. Personally, I think 220bhp, but will say 240 to be fair. With no means of live mapping the fuelling OR the timing, it's just not practically possible.

christian i no you had a fine car but have you driven my car NO so how do you no what bhp it is maybe the rolling road graph lies or from what your saying harvey has a crap rolling road

7k is a big budget considering that he does not have efi, steel bottom end and a non gt30+ turbo!

Rob,

Is that Luke who owns Enhance? i have used him for my engine work and he is very good!

ok from reading of you guys you doubt the bhp what sort of figures would i run into if i wanted efi,steel bottom end gt30 and mappable ignition

[morph]

I am not doubting your BHP mate, if you made 270 on harveys rollers then you should be happy with that. Harvey certainly knows his stuff, he makes 800bhp cossie engines that are amazingly reliable so i doubt he would have problems getting extra horses out of a rs turbo.
Mark shead produced 260bhp many times from his setups on mfi and were rolling road proven plus he has produce 280bhp from mfi, so its not impossible.

you would see 300bhp or close too with efi,steel,gt30,mappable stuff.

but were only talking about another 30bhp there worth it for all the money

don't look at 30bhp, look at the reliability factor that efi can offer, the car will be fully mappable which would mean you will burn the correct amount of fuel, have the right amount of ignition it would have less chance of detonation, the power delivery can be made to how you like it.
i would go for efi setup at minimum to keep your car more reliable.
give Luke a call as he can give you efi at a very resonable price.

hi mate ring luke 01444881949 he can tell you a lot more.

[Rob_DOHC]

Not really but k

i suspect mfi running any where over 200 brake is fueling all over the place.... efi would make the car alot more drivable let alone economical.

and although any one on here would recommend changing your rods if nothing else, fitting efi and running the same power which i suspect you would anyway would not suddenly put more load on your conrods etc....? so converting to efi shouldn't actually mean any bottom end work (although if your sure you have standard pistons/rods etc you should)..... However im sure if the lump cost 7k to build it would have decent rods anyway????? especially as harvey gibbs built it and more than knows cvh weaknesses......


I personally would look at running a gt28rs and looking for 270 brake again on efi. You would have a far nicer car to live with.... instead of a peaky cock inlarging 300 brake


Rob,
