Rob's gear changes let him down. Explanation for the lowish mph given. Case closed. The turbo setup requires a good flat change or your going slower than stock. Reaching a particular mph requires 'time', less time if you have more power. If you lose time by dropping out of the power band then you lose mph ,end of story. Agree about the 'big hp' claims and no performance issue. It's an oldie but a goodie.

morely quickfit are great. I have used them for ages. Pat is a legend!

It was fast. Not as fast as my car (when I was driving with the old Nitrous kit activated). The test was for me was the cars pulling power in top gear, the speed at which it accellerated. Not 'felt' but, rather 'seen' from the speedo side of things. At the drag strip you can completely stuff the 60ft and still end up with a good terminal speed. If you drop revs between gear changes by shifting too slow then the terminal is greatly effected. The problem Rob has is that his TD06 has a rotory sized exhaust housing and he's got the standard manifold making for a power band that is a little unforgiving. 111mph from my experience is NOT an indicator of this cars power potential, only an indicator of the average power rob was able to maintain over the 1/4 that day.

Need me to drive? no worries rob! I've actually been in Robs car, it has the power. Rob is a little too kind in shifting gears, something he can get help with I'm sure. Rob how about giving us the 660 and 1000ft times and speeds, this will hopefully show the issue you had with the power drop.

tolunene injection works quite well. There was an article in a very old issue of fast fours and rotories. You use a cold start injector/solenoid? for injection. toluene likes to burn at a richer mixture than regular fuel so within reason the metering would be pretty easy. No additives are required. The other one I was looking at was isopropyl injection using the moreys upper cylinder lubricant kit. Cost of the kit is $60 and mounts neatly within 20mins. even comes with a bottle of the stuff. Can get the kit from super cheap or where lpg gas conversions are done.

Hey if gtrken reccomends them then they must be good for drag racing I might be interested in a few weeks, can't knock a $200 tyre can you.

paul, got the price from rotormotion yet?

yep his mph is definately good for a much lower pass with a decent 60ft even on road tyres

They are rally tyres. good for going around a bitumen stage in your rally car, don't know what they would be like on a drag strip. But for $200 a tyre the experiment will be cheap.

rob, looks like you were playing outside the engines power band on those runs. 111mph is a tad low. Traction is always an issue at the drags, some days more than others. I think it's pretty hard to go to the track and expect great times without good tyres. Most of the issue is in that first 60ft, get past that and it's usually a little easier.

I think the T.S is like a dyno reading a 'relative' indicator.

I have a green light to take the volvo down to run it but, I will wait till I have the carby sorted out and perhaps fit a line locker as running on gas is just no where near the fun.

the terminal speed will be a good indicator of the power. At least the owners of each vehicle have a previous terminal speed as a refference, so I'm sure there will be quick validation of the power claims (as relative as they are to the particular car and dragstrip). I am another who doesn't place alot of emphasis on the dyno as the sole performance indicator.However having had a ride in Robs car I feel confident there is a strong case for defending the power claims from that dyno when he visits the strip this evening. Cheers Dave

I think maybe pointing the finger at the flow rating on side feed fuel injectors might be in order. I mean when people say 370cc or 550cc for any injector that rated delivery is particular to some kind of set pressure and fuel flow delivery. The fact that increasing the fuel line diameter from whatever to 1/2 inch can yeild additional headroom for fuel systems at the final delivery point speaks to some of this issue. Simply 'flow testing' at your injector service center can't tell you the delivery potential of that injector in your vehicles enviroment. It is a fact conected to properly setting up the right fuel jet on a nitrous system. Each jet, although sized according to the hole diameter must be flow tested against the flow jet on the point of connection to the fuel system. Anyway anyone like to have a go at the standard for injector sizing?

I saw the ecu when I bought the turbo, thanks again Hicks. It is the 'genuine article' he ran a few 13.7 passes with it and little else. I guess that qualifies it as a good unit.

B-Man, What was the $ damage for a set of those? These still use the standard hydro' lifters?

check pm

Sydneykid thanks for the info. What's the mildest grinds availible for the tomei Poncams?

4.5hp is 1.3% variation on the old power level. taking into account the temps have been warmer and most of the tuning time is spent on the midrange, since the peak power is plenty for the stock injectors and so on i doubt they would have tried too hard on that end for good reason.

oh. Hello paul then. Hows the engine?

hello people.

Yep highly accurate for a Correvit timing run Not a real dragstrip. The times are always a little too generous.

You da Man! I'll try to bash the insurer over the head to authorise a new piston set before the end of the week.

sydneykid , who do you get yours from tho'? Also what part No. for the Tomei unit's dude?

the answer to the first question is ; no I'd say they found alot more power for the 119mph run, we are talking a good 80hp or so I reckon at the engine. Possibly they ran lower boost on one of the strips.
