Jason,

Yep, it's charge temps I am concerned about- I think Tidgy is aware of that too, I think he was pointing to oil temps as an additional concern.

Thanks for the offer mate, but I'll be going with the front mount. Whilst the new age OE Top mounts are a big improvement over the classic ones, Fundamentally they're still in the wrong place, i.e. on top of a baking hot engine! I'm sure the new age ones can cope with 400bhp+ as the tuners have said, but they still won't be as good as a good quality FMIC and I want the issue of charge temps dealt with totally i.e. no concerns about the areodynamics of the bonnet starving the TMIC of cool air at sustained high speeds, no more reduced performance after sitting in traffic etc...

Thanks again for thinking of me though!

Well if your issue is controlling charge temps, then a front mount will deal with them. On my STi4 TMIC I was seeing temps spiralling way beyond 50 C with only 10 seconds of full boost, although in everyday running it was OK as long as you kept moving. It could have had 1000bhp and been fine - as long as you only put your foot down for a second at a time. As soon as the FMIC was on, it was totally in control. I see 5 degrees over ambient in most conditions, 15 degrees over ambient with continuous hard track work. That's with 1.45 bar out of a TD05.

yep i did realise charge temps were the issue, but charge temps mean nothing if you have no engine cos of oil temps cooking the engine. while mine hit 105-110 i always backed off at that point so no idea what they would have reached.

on the subject of chrge temps, 1 degree C higher is equivelant to roughly 1bhp less, front mounts are proven to reduce them temps in all conditions so answers itself.

p.s. heres my cooler



and what the front of my car looks like now



in the second pic you can just see the top of the cooler between the bonnet and the bumper

Dont know the difference between the greddy and the apexi but I dont know anyone who rubbishes the apexi

Did I notice a difference?


Err yes just after JGM mapped it

oh and I run a Power FC as well

and its a St/b

I've detailed all you need to know about a VF35 converstion here. Talk to a good mapper and you'll get better advice than this forum, which can often be misleading

Tidgy

well if you wanna spend months under the car then by all measn do it floyds way

even you admit floyd theres a hell of alot of time (fair play to you by the way) gone into it, for ,if were being honest, not much performance increase. For the time you've taken you could have eaisly built a 2.5 or 2.33 and then had 400bhp.

Excellent advise..

Not sure what other mappers are like, but Bob R has given me loads of sound advise over the years, the reason why I recommend him so highly..!

Er, not much performance increase over a TD04? Are you mad or sensless?

I didn't have the money for a 2.5 or 2.33 hence the 'economy' thread

There's a lot of time taken if you do the job properly, or none at all if you pay someone else. Everyone expects 350bhp as a minimum these days and they want it for nothing, then people only find 450 interesting but don't realise the big costs involved to get there reliably, especially if you track the car.

Tidgy

sorry should have clarified, ment for the effort entailed, you are talk a 50% increase but not far off the cost of getting there by other means

Floyd

iTrader: (9)

What other means. I'm not sure I understand?

F

Tidgy

well common one tends to be, turbo, front mount, decat etc more just throw a few larger parts at it, wheres as floyd has gone down the route of top mount, polishing, airflow tricks (nothing wrong with that by the way can make a big help) and then turbo, so more fiddly bits rather than just brawn is prob how you could describe it lol (correct me if im wrong floyd cos i didn't ready all 13 pages lol)

Great read floyd. A VF35 on a classic (with supporting mods) is a great upgrade isn't it. Bob mapped mine too and -even with the sub-optimal intercooler- it makes for a blooming quick and exciting car!!

Yes, I see what you mean now. I agree, the majority go for the bolt on formula, which works well but I wanted the most for the least IYSWIM as well as a foundation for further upgrades. There's nothing wrong with the 'brawn' approach but I fancied doing the fiddly bits for fun and I wanted it as stock looking as possible.

Thanks for the comments NS04/BURT

BTW, I haven't finished yet and the next upgrade is in progress!

Well I copied a few of the things that Floyd did (Ex/TB/IC porting) because I had the time and they were no cost, and as a well known Jock says "every mickle makes a muckle"..

The results, well I'm getting the very top end of what a VF35 should produce >340x330 and it feels like it too..

IMO, if you have the time and are that way inclined then the little things are worth doing, at any level.

PS I also did Floyds little fuel pump return mod and put it this way my car has never suffered fuel cut even giving it some right hand 10 miles into the fuel light..!

Thanks Jason, btw I have almost completed that spare throttle body

A few people have benefited from my header tank insulator mod too! Some have comercialised it!!!
