View Full Version : Red top turbo engine
Was at Track & road yesterday (rolling road) and the car before mine was a Vauxhall Tigra with a red top turbo lump in it. Its blue with a awful pink panelled interior with cage.
Has anyone ever seen this on the quarter mile?
Speaking to the bloke and he says that it done a 11.3 1/4 mile at 137mph on road tyres. On the rollers it reached 520bhp at the fly. Didn't know they have managed to get it that high, I know you take it with a pinch of salt but even if you reduce 50bhp off that, its still crazy. From what he was saying as well was still running a standard crank. Are these engines that tunable to that sort of power and will take it that well.

Track & road are pretty accurate, and mainly specialise in race cars... so you can believe what you see on their dyno, they don't exaggerate like some.. was it a spaceframed hot rod type of car?
The vauxhall se\ce\xe small block and bigblock redtop engines are really tuneable - the original heads were 'coscast' and really sought after, its not too difficult to get 150hp out of the NA 1600 8v lumps, the autograss boys have always got some rediculous hp figures out of the 1 litre 8v nova engine, and figures of 300hp are pretty achiveable with the 2litre 16v redtop (normally asprirated) - SBD developments have done some very, very quick engines of this type, so seeing an extra couple of hundred hp from using forced induction isn't too suprising from a 2 litre 16v.. How long it will last is anybodys guess?
Bear in mind though that the cosworth boys have been getting 500hp ish fairly routinely since the RS 500 sierra touring cars in the 80's and thats on a pinto block design that dates back almost to the 70's, if not older... all comes down to how much £££ you want to pay ;)

figures of 300hp are pretty achiveable with the 2litre 16v redtop (normally asprirated) - SBD developments have done some very, very quick engines of this type, so seeing an extra couple of hundred hp from using forced induction isn't too suprising from a 2 litre 16v..

my little bro had 250bhp on jamsports rollers with his old throttle bodied XE corsa :)
phase i 16 v turbo

I have seen him run at the Pod, they are a group of mates that have been working on the engine for a few years. It was 500+bhp last time and he was live mapping at the Pod.

Yes, that was last year, he sorted out a GT35 turbo for the car but is not making much more power and and its not as easy to drive as the older turbo, think he is going back to the GT3076 which he had last year as that seemed a better turbo for the car.
not normal

Was going to say TOTB :)... ive seen it at pod to a few times... Nice power :smokin:... Prob to small a power bracket with the GT35 at a guess??? awsome build tho...:agree:
thats andy speck, he goes quite well doesn't he, given andy nichols a run for his money a few times. I friend of mine building a drag c20let tigra knows him fairly well.
btw, the 500hp is quite believable. it runs in excess of 2bar, and to trap at those speeds takes about that sort of hp.

also saw this at pod last year

It was running 20 psi and was still making more power at 7.9k where they put the limiter.

What in? F7P?

Red top turbo, this is what the whole subject is about ;)
over 2 bar I was told - then certainly take that 520hp with a pinch of salt if he really was only running 20psi.
Scoff ste will give you a run for your money in his tigra if he finishes it before pod have you spoke to H
The blue tigra is owned by a lad called speck i think if its the same car

As I say mark, his name is andy speck. Ste's tigra is comming on isn't it, he'll certainly give me a run :) Although I won't be going to that USC nonsence so he'll have to come to a real race day to catch me :p
haha yea he will do mate stes just needs the intercooler pipes doing, drivers seat putting in an the drivers side part of the cage then its going to get setup an maped so he can run it in then back to be fully maped, as long as the dvla dont question it or want to see it
Ive just spoken to ste who is building the drag car scoff spoke about before an he said andy specks tigra is running more than 520bhp with the bigger turbo fitted
over 2 bar I was told - then certainly take that 520hp with a pinch of salt if he really was only running 20psi.
Quite possible really, 20 psi did seem a bit low, but could have misheard him when chatting, that thing does make a hell of a noise on the rollers
520 is about spot on for a properly built engine and GT3076 on 2bar. I know I'm always saying this kind of thing but that isn't any kind of "limit". I know Field Motorsport had a rallycross XE turbo on their dyno that made 640 and there are yank drag motors purporting to put out 900. I'm sure the blocks are a wee bit fragile at that though...

Bollocks to vauxhall and their xe, yb is where its at. Aussie touring cars in the late eighties running up to 750hp in qualifing trim.
Double fail.
4G63 FTW http://www.magnusmotorsports.com/raceteam/index.htm :)

umm, think I just keep saying, if someone puts the money up, almost anything is possible....

ooh, is that a tuner making a power claim?:laugh:
Daggers out! :laugh:
Nigh-on 200mph t.speed out of a 2L isn't bad though.

Within reason. Nos gas aside, there's only so much you can do with a 1.4L 8v carb-fed engine.

you could run it on methanol like your mitsubishi example
True, but there still has to be mechanical limitations somewhere down the line? eg, someone like Stuart Clark must surely be on the fuelling limits of the 32dis?
Just out of curio', how many valves did the 1.5L turbo'd F1 engine have?

depends upon how many cylinders they had
Soz, I was referring to the Renault V6 jobby.

I guess that'd be 24 then...

don't think that 1400(!?)brake mitsi lump was trying to run std inlet side;). Lose that bloody carb.
Big drag motors making near 1000bhp/litre (depending on who you listen to) only have 2 valve heads.
