I gotta say, I imagined worse! The rollcage really kept the over all shape of the car!

Good to see your in one piece john ,

Makes me want to go and do the rally thing again !!

About the shocks , my friend started running proflex suspension on his darrian after using LEDA , the difference was night and day and only £500 a corner , an engineer will usually come on the first test session to help with set up .

Ive found , you cannot budget for dampers , the more expensive they are , the better quality they are aswell , this relates to how you feel with the car. When running the race car , dynamics suspension allowed us to tune so finely , an extra 100 kgs of weight had no detriment to the way the car felt .(the extra 100 kgs was to get to the weight limit)

Vance's car is the former Karl Yardevall 740 turbo.
It has a 2.3 turbo that is making 300lb/ft at the wheels, a proper 4 speed dogbox, Sellholm suspension goodies, and is otherwise still in need of a LOT of help.
Vance will have a LOT of fun with it.

I'm now needing to get my Volvo back together. Got a taste of it this last weekend.

John.

Mr Lane, can you tell me your 'estimated' power of your engine, normally aspirated (i.e without boost?

no offense, but for a turbo engine that is not exactly what ones after, especially with rally cars.

curious why your after that number?

..because a 500bhp turbo engine, running only 11 psi, would be around 300bhp in normally aspirated form.

Yes, thats right.

A 250bhp n/a prv V6 is sucking an atmosphere of pressure. Add another atmosphere of boost (14.7psi) and the required fuel and the absolute maximum you 'could' acheive is double the power....but this is never the case as the atmosphere of boost is heated, the exhaust side of the turbo system is more restricted than a normally aspirated system, the engine compression is usually lowered, and the head design cannot simply flow double its previous capability. The more boost, the more pressure drops we have across inlet, plenums, valve area etc...

Rule of thumb is around 18 psi of boost is required to double the bhp output of a normally aspirated engine.

Holy Thread resurrection Batman!!

I never had the car on the chassis dyno when it was Naturally Aspirated.
As Naturally aspirated with a pair of IDA-3 Webers it was faster then the N/A three liter.
When I gave it Electromotive injection it really woke up in the top end.

It did then get turbocharged which made it a different animal altogether.

The Fire Breathing Monster is currenty taking up space in my sister-in-law's steel building behind her house....... It will soon be making the trip to our new place for some much-needed attention. I am looking forward to remapping for more power, more torque and making the spectators run even further, faster....... You get the idea.

Stay tuned......

Are there actually any dyno plots to see of the turbo engine?

It was misplaced years ago if in fact I ever left with it...... I sure will get another when it gets tuned again. This will likely be this coming spring.

504lb/ft at the wheels at 4000 with 11lbs of boost is the one that was most memorable on the chassis dyno. It has been much more amusing with 15lbs of boost, which was done later but not on the chassis dyno. As the next chapter in the project progresses I will certainly put an effort into keeping track of paperwork. In the past I have not cared enough to do so.

Show of hands.....To all who have ridden in my car.... Any question as to the validity to the power claims? Hee-hee......

I've got a number of requests for pics and managed to find this old thread in a search.

Here is the rallycar and stories to go along with.

In one of the very first posts (if not THE first post) you will find a link that will take you to some manner of picture hosting site. Many pics there.

blast! I came in here hoping to find that it had been resurrected.

Oh well, I'll just have to satisfy my rally jones' with the first few pages.

edit: John, (hell, any of the johns ) why the unequal geometry on the firewall to strut tower tubes off the cage? Is it just the photo, or does the drivers side tube actually have a big 'ol kink in it?

No, it is a-symmetrical in real life IIRC. It ties into the strut tower slightly differently to make the geometry more or less effectively the same. The bar has to clear the brake servo on one side and the other side sheetmetel baffle thing is where the air-inlet to the turbo goes as a sort of snorkle IIRC.
That car makes me giggle the couple times I've seen it just looking at it.

Holy crap.

Can't believe I haven't seen this thread before.

Damn, that's insanity, good to hear to walked away from that one (which was what, a few years ago? lol)

This PRV motor is far from perverted. I'm pretty much speechless.
