any ideas as to power???

Pikey Motorsports · 06-10-2008, 18:15

hey all, i have jus got a mk2 astra gte runnin a early redtop,
it has a huge induction kit (make unknown, THINK k&n)
wiseco pistons
enlarged throttle body
chipped ecu (make unknown)
huge 8v backbox

will be gettin stuck in tomo so may know what type chip then,
but anyone any ideas of what she should be running?
im thinkin about 170BHP?
also, is the huge induction sapping power? have heard that an original sfi airbox with k&n panel filter is best way to go on these?

cheers!

Maybe 160bhp at most if its a healthy motor.

Pikey Motorsports · 06-10-2008, 18:38

how do you figure that bud?
standard redtop 153 BHP
i was goin on roughly 10% for chip = 15 BHP
plus induction, t/b , pistons, exhaust...??

wishful thinking.

Maybe the engine is worn. You'll be lucky to see 140

Pikey Motorsports · 06-10-2008, 18:43

engine is healthy as mate, 79,000 miles pulls like a train. no way its that low!

hahaha Dude you'll get 5brake from a chip if your very lucky...
And the rest will give you a few.. I'd go on 160 if its all ok..

Pikey Motorsports · 06-10-2008, 18:52

ok ok 160 i can live with, 140 wud be depressing lol guess ill have to wait til tom_spanner sorts this rollin road out eh!
whats best way to go for a reliable 200BHP?

**Benn** · 06-10-2008, 18:55

Fit a let, or spunk a huge wad on tbs..

turbo_nik · 06-10-2008, 18:57

Maybe 2bhp if you're lucky.

Yay, overfuelling!

Maybe 5bhp on a nice cold day.

0bhp.

So I make that 6bhp.

Your mileage may vary.

Pikey Motorsports · 06-10-2008, 19:07

ok.... aaargh! lol well standard airbox goin on very soon, then new straight thru s/s exhaust inc 421 manifold. take it from there! am thinkin tb's......

Rs1 · 06-10-2008, 19:18

Aye TB's is probably the best way forward but only on a healthy engine. I'd get it serviced first and chuck a set of ARP big end bolts in there before you get the TB's.

Pikey Motorsports · 07-10-2008, 17:38

cool thanks for the tips, wont be doin anythin except gettin her perfect for the time bein, e/m light is now back on, an juddering like mad when u come off the throttle. thought was rear engine mount but done that an still same...

**jamied** · 07-10-2008, 17:58

I have a customer that wants his xe stripped down and rebuilt like new, and when i say like new its a complete strip down, new bolts, cylinders, valves, shells..ect, ect.
Then im making a set of TB's (from scratch with the alloy blocks coming in to mill out) and tailor made to the engine...should take about a month/2 months to do...and the cost is huge but this is what he wants....its not shy of £3k to get the power he wants.

Pikey Motorsports · 07-10-2008, 18:14

whoa! so what BHP u aimin for with that then??

**Benn** · 07-10-2008, 18:28

3k is cheap for a tb set up tho j, to get them running right it will cost more than that..

thats just the start mate...i still need to set up the ecu system and rolling road it, the £3k is just parts at the moment and a bit of labour.

Jamied, wouldn't he be a LOT better off using one of the SBD throttle body kits - they're a very nice piece of kit - Jenvey hardware and MBE ECU that can be tailored to suit requirements.
