Jimbo,

But surely that'd cost a fair few quid mate??

And i'm STILL not convinced a .48 housing does 380bhp...

 

Yeah probably but the question was best road spec not price, you could do it without the studs and wrc gasket and porting, but the beadwork makes it so much better, the studs and gasket are just overkill so that it will never have a problem, we still have a lot of customers go this route with new builds though.

Your more than welcome to come up and watch a engine on dyne next time we have one on, or I can show you some graphs.

 

But isn't it on it's VERY limit @ 380 Jimbo??

 

Don't get me wrong, i agree 100% with the headwork, 4x4 Inlet and inlet cam, i'd love to do that with my setup tbh, i bet it'd be a different car again??

Daft thing is i have the 4x4 Inlet sat here doing fook all...

 

Get it on there then

If you measure the back pressure on a .48 housing your wouldn't want to take it much further.

The thing is when you spec and build a proper engine, you can tail the boost off and it will hold the powerin there, so its not so drastic as a poorly specced engine where you have to hold the boost in.

 

Still waiting to see some of your graphs with engine specs jimbo?

T38 ones and and t34.48s and t34.63s

Whats the most power youve seen on a t34.63??

I had a black saph the other year that had one of your t34.55 light blue conversions and it was lovely didnt miss a beat had a dyno sheet with 382/372 iirc or there abouts at 29 psi peak and 27 psi held

On our old rr it did 355 hp and 360 lb ft but at a little less boost so about right..

That was long studded wrc gasket 34.55 nick wapples head 4x4 inlet light blues bd14 inlet 8 ex 7.6.1 cr..very nice little engine but had done two turbo before me in 12k and one on me in 2.5k..


cheers danny

 

I know sorry mate I will sort some out, sounds about right, boost dropped a touch always loose a tiny it into car, I'd expect a little more than that though,

Was it 2wd or 4by?

 

So in a nut shell Jimbo, well Danny etc etc..

Standard Engine
Different Inlet Cam
4x4 Inlet
Cooler
T34.48/55/.63
55lbs/Blues
Headwork (midly) ??
Live Map

Should see you a strong 360-390 yes with similar torque??

 

Id guess around 370 with similar torque, its not just figures though these conversions are awesome on the road

 

It was a 2wd black saph lovely car i bought of here from retro al..your old man done loads to it ..

I sold the engine on here end of last year begining of this and you commented on it then??

That was our old dyno mate but actually read high if anything!!lol

It was a quick car on the road and held around 4 psi on the road too


cheers danny

 

Jimbo, as you know i've been lucky enough ti have some lovely cars, BUT i've laways said and this is my opinion, the best road going car for me was my old 3dr running T34.48, Greys etc etc NMS live map @ 32psi peak made 363 and similar torque and it was just fantastic, SO punchy.. obviously if i'd of had headwork, Cam, 4x4 Inlet etc it'd of been even better, but for near on stick on mods, best one outhere imo..

 

Spot on mate
Fully agree!!



cheers danny

 

I agree its all you probably need but for me imo its not enough,i get bored with this power after a couple of hours and need more!!

Imo the best power for the road is a well specced gt3071.82 engine 450/450+

It comes on as well as the above specs and the bang is obviously harder but the power more linear to the rev limit

My gt30 spec engine that iv done comes on boost and has as much torque up to 4k as my nms built and mapped escos and after 4k will obviously murder it!!



cheers danny

 

I think I remember it now you say that! 24osi? If so that wouldnt be far wrong

This in a 2wd car is ace

 

is there any point having a fully ported head on nigh on standard engine or is it just overkill.mines running stage 3 t34/.48,with restrictor which i want removed 500 cooler and cone filter.

 

The problem for you is the same I have, we drive much more powerful cars on a daily basis, and come the weekend we jump into animal cars then everything we ever drive again won't feel as fast!

This is why I'm not having a t34 engine and something more similar to a 3071.

 

Depends on how big the ports are, not really needed at stage 3 fella.

 

that was my thoughts,ive got a 200 block here that i wanted to build up in the future and was going to use my 2wd head on it.been taking great interest in this thread for the best spec to use,are tuners running close to standard compression these days?

 

Depends who you go with everyone has their own ideas, but standard or a bit lower seems to be the norm

 

Yeah your right!!

I remember going to lydden hill last year when i drove that same saph iv mentioned above and after a day of gooning it around in my race car i had to drive home in the saph..

It felt like a rolls royce to drive so quiet and smooth but my passengers said fucking slow down you loon as i was in the red line every where!!lol

Felt like i was going backwards after driving my red one!!



cheers danny

 

Lol! Worst one I did was try changing gear without clutch straight after a sesh on track

 

Std pistons with large valve cut outs and a good deck hieght on the head is my prefference


cheers danny

 

Not quite sure what its there for, think its to increase the pressure or something? dont know if there are anymore mod's to be done?

 

Bet that sounded nice??lol

Il have to watch that now im going for the seq box!!


cheers danny

 

Ooh what you gone for?

No damage just a wee grind

 

You can only do that mod when using a 2wd head!!

No other mods needed



cheers danny

 

I think (don't quote me on this) it's to increase oil to the head (I'm guessing the front is a main oil feed for head) it's also done slightly different when using solid litters

 

Iv gone for the elite il300 6 speed with uprated dog rings good for 600lb ft

Same as jackos and a few others of here


cheers danny

 

That seems to be a cracking box in daves car, real quick on the change.

 

Iv not experienced it yet but have had loads of feedback from people on them..

Just hope it can deal with my new power and torque!!

Will soon find out i suppose..


cheers danny

 

Is it woth getting done Dan? i have a 2wd head

 

What makes you say only 2wd heads Danny?

 

SCS engine

Low comp
6 Long studs
WRC gasket
T34.48
Light blues
Behr RS500 cooler



Thats after 30k of use without having anything replaced.

DD rollers as well Danny just to keep you happy

 

Is that in the tiger striped 3door?

 

Yep, that broke your rollers

 

Lol them poor rollers were only 300bhp ones

 

I believe it was your old man who said switch it to high boost

Should of known what was going to happen being that he built and dynoed it back in the day lol

 

Regarding what gear it was ran in I had that argument with TOTD on the day, the car ran a 3.9 cwp too but they insisted the DD manual says that ALL cars whatever the gearing are run in 3rd.

The boost would peak much higher on the road than it did on the dyno that day but I wouldn't of expected much more power

 

Well they wouldn't have it and I did feel it let the car down slightly. Went very well on track for what it was tbh !

Do you run most other stuff in 3rd then ?

 

This r/r day was talked about for ages as Dingys 550hp Escort made about 400 iirc !

That said 390lb ft isn't shy !
