guess the BHP

[blingsta]

i will be taking my car to rolling road very soon, i really dont know what to expect, any guesses? its a standard 2.5 with a garrett t3 cossie turbo running at 7.5psi

[gcorky]

should be over 230...woulda thought.

[fuzzy]

surely it'd be in the 230+ what figure do you have as a thought in your head that youd be happy with?

[blingsta]

would be happy with 250, she moves like she got that anyway, and still a few psi to spare !! suppose i'll have to wait n see.

[fuzzy]

whens the r/r session?

[blingsta]

hmmmm, turbo'ing a standard 2.5 lump. interesting. How much does that cost to do?

roughly about 3k all in, well worth it though..

[blingsta]

whens the r/r session?

Havent really set a date, but very very soon, after tommorrow's meet at lakeside, i will look into best close'ish place to me for booking her in

Erel,

My Gtech thingy kept flashing between 240-270bhp @ about 7 to 10psi. Although this is all down to weight input etc I used the same each time and saw aprox 20bhp more each psi it went up.

Now my fueling was pig rich top end as I had no spark control then so I would think you're gonna be well over 250bhp at the crank or 200rwhp.

Either way I'm 100% positive you'll be well over 230 mate!

No matter what you get tho, my money says afterwards you will want MORE!!!

[tim-ix]

Are you concerned about blowing the head gasket or otherwise exceeding the limits of a standard M20?

The head gasket isn't exactly renowned for it's strength anyway. It'd be interesting to see what the results are of progressively turning the boost up, i.e. when will it go bang? Obviously more interesting if you're paying rather than me.

I reckon you'll get over 230bhp but it's the longevity of that power I'm interested in given that you're otherwise running a standard engine. Have you done any other mods or is it literally just the manifold, turbo, fuelling and pipework?

Best of luck in any event.

[fuzzy]

id also have reservations about turboing a non turbo engine without uprating anything else regarding how long you have before it goes boooom hopefully it lasts

[blingsta]

yeah, lets not jinx it now!! the block and internals are all standard, the only upgrade is the m/s which controls fuelling and spark, research shows that a stock m20b25 is good for upto 350bhp before it needs strengthening.. if i remember correctly, i think fozzymonster maxed his garrett t3 at 13psi without any issues, oh and ive also got the non stretch head bolts clamping the head down

[exup]

Im sure it will make you happy what ever the figs are
good luck at the R/R

[blingsta]

Thanx guys, will let you know figures

[Ant]

hmm, testing my arse dyno calibration eh mate

do not up the boost on the dyno, I dont care how tempted you get, boost level revisions only with a remap dude !!!!!!!!!!!!!!!!!!!!

[Turbo-Brown]

Eeeeeeeasily over 230!

Got 270 out of mine on 7psi so if you don't make 260 or so I'd be surprised

[exup]

Get back to work ANT
There must be 1000, s of E30 that need Your help ,
get converting , so many to do , no time to waste ,

dont worry bout that mate, it wont be touched, i done that once before with the bleed valve if you remember.. i remember the outcome !!!

[mac325i]

i voted 230+

i can see 250+

sorry for random post but had a few

[Gouki]

i reckon over 230+

[mattG]

50bhp if you blow the head gasget

only joking fingers x 230+ but as they say it's all about the torque

what's the max psi do you reckon you can run?

[blingsta]

i reckon 10psi, although it would take 1 or 2 more.. Anyway, tommorrow is the big day, im going for a power run, no mapping.. so fingers crossed, i'll post results tommorrow..

[gcorky]

good luck m8....

[ric325i]

fingers crossed!

magazines always say people are disappointed by the out come of a r/r because people always over estimate.

i have a funny feeling you aint been over estimating !!!!!!!!!!!!!! 230+ easy!

i would love to see a safe 250/260bhp. (safe in respect of the engine-not how it drives )
