bhp estamate

[R5GTTRaider]

lightly modified c1j,

it has been rejetted to suit 18/20psi, forge dv and properly flowed oem i/c and running 14psi by the means of turning the acuater arm rod inwards 5 turns

im wondering what would be a estamate on bhp? 130

am i dreaming? or under estamating? :confused:

im hoping to get a group of kent lads and head down ashford RR on 2nd 3rd may?

With 18psi and decnt fueling you should be seeing anywhere from 160-180psi...

RR day looks interesting, if you want me to look into it i will happily do so.

standard turbo Granville

standard turbo Granville

Point taken.... forgot about that...

Maybe 120-150bhp then...

[Nayls]

jetted for 18/20 psi but you're running 14psi???

[dangerous dave]

my little 5 did a 15.6 q/m with 12psi, air filter and a sidey on toyo r888's... i forget the top speed but i was said 130bhp was about right for that..

my old 5 was r/roaded at 140bhp at a 15psi many moons ago at bbt..

only way to find out it get it on the r/r or q/m, we all might guess 130/140 but it might run like dog sh*t.. :p

[Os8472]

I'd say 150bhp 166ft lb, basically cus thats what mad with those mods

[R5GTTRaider]

Nayls:
well it has jetting to run 20psi but im unhappy running 20 atm due to rear mount gone or going.

dangerous dave:
it dont run like dog ****, ive pulled away from many cars id not expected to

Penfold:
120? its 118 @9psi so around 150?? sounds intresting :D
whats Q/M ??
and please could look into a rr day even if its 5 of us. essex or ashford. well im defo going down on 2nd/3rd or 16th/17th but defo doing it as its £40 at ashford


Os8472:
take it thats what u had on ure running this setup?


to be honest it my engine realy sounds like it want more boost!!:wasntme::cooter:

Pretty much, I had a T2 turbo running 14psi, a strapped intercooler, dump valve, panel filter and 2" system and it made 150bhp and 166ft lb of torque on half a dozen different dynos

says on your profile you have a t2 turbo matey!? wont you need a bigger turbo to run 18/20psi boost?? think most only manage 15psi on a standard t2 or you just stickin at 14!?.

[R5GTTRaider]

well dint knkow were that spung from but when i put on a free (given) manual boost controler, which i was soon to find out why it was free.. i had it on its lowest setting bang 26psi i kinda took it of sharpest , thought is do some fiddling with the spring and cut it down to reduce the resisatance on the ball and spring that still managed 22psi!!

when like $h1t of hot shovel but im not realy wanting to keep my turbo for 5 minutes!!




any way, what bhp is a punto gtt?

[scratcher]

I think what Blick is saying is that a T2 would be able to make high pressure like that, but not for too long. And it won't be efficient, it'll be blowing hot air which is not too good.

[R5GTTRaider]

yer i see what you mean, well 14/15psi is good enoth for me, eats most cars, plus my mate in a punto gtt gave it all the talk and then proceded to thrashing him to 70 on a duel carrage way

[Nick k]

i have a punto GT1, 136 bhp standard, Seb0 chip fitted and a big turbo its producing about 160 bhp @ 17 psi. Great in a straight line, sh~t on corners and very laggy.

My R5 cab has a T2/T25 turbo, 270 cam and is running about 14psi.

At mallory park last year there was nothing between them on the straight but the 5 just drove away on the corners :agree:

Punto GT2/GT3 are 130bhp standard. Punto's are very laggy until on boost so a 5 with a T2 will always beat a punto from a standing position.

I recon your 5 is proberly producing 135/140 bhp. Not alot more with a T2.

[R5GTTRaider]

i thout puntos were 170, tho i dont know much about puntos
yer 140/5 could well be as it feels as quick as a corrola gti 16 i had and that dyno 144bhp,
i need to get engine mounts sorted first before any rr,
just need to find a decent priced one in kent

I run a T2/T25 hybrid turbo @ 21 psi and the rolling road computer said 165 HP and 220 NM... fueling is good according to my AFR gauge...

165 @ 21psi seems a bit low does't it ? Ewok is Running 18psi and getting 180bhp.

[5alldaway]

im running t28/t3

181 bhp at 17psi, thats what the rolling road says :D

so say the rollers, that was with a small back end t25. Switched to a bbt28 with. .49 rear and it made 176@17psi cranked it up to 24psi and hit 208bhp and 216lbft before emoting the carb at 5500rpm. Hopfully getting that issue fixed this weekend and will see if I can crack 104+ mph at pod:-D

[Matt Cole]

I have 225bhp at least on 9psi standard turbo!:D
