phazed Posted February 11 Author Report Share Posted February 11 Good luck with that. Interested to hear about your results. Are you going to do a before and after Dyno run? 1 Quote Link to comment Share on other sites More sharing options...
Nitro V8 Posted February 12 Report Share Posted February 12 I would like to but timing and cost seem to get in the way. I'll see if I can. Quote Link to comment Share on other sites More sharing options...
phazed Posted February 12 Author Report Share Posted February 12 I always had power runs from Surrey rolling Road at about 50 pounds a shot. It was worth it. I did a huge amount of upgrades to my 5.5 TVR and it was always good to see the torque, BHP, and to see if the fueling was correct. definitely recommended if you can. if you do, try and emulate similar conditions. I.e.: cold dry morning as this does make a difference when comparing like for like. 1 Quote Link to comment Share on other sites More sharing options...
edc Posted February 12 Report Share Posted February 12 Likewise I used Charlie at SRR as down the road from me. Base line then runs after each mod. At the end I got all the graphs overlaid for my old 986S. 1 Quote Link to comment Share on other sites More sharing options...
Nitro V8 Posted February 12 Report Share Posted February 12 I am going to try and find one a bit closer to me. I know the results will not be comparable with others but it will at least give me a before and after figure. Quote Link to comment Share on other sites More sharing options...
edc Posted February 12 Report Share Posted February 12 Don't worry about the figure itself, it's the change you're looking at. 1 Quote Link to comment Share on other sites More sharing options...
edc Posted February 12 Report Share Posted February 12 For example, your research points you not to do the throttle body, but my Dyno showed no loss but a gain. Horses for courses. 1 Quote Link to comment Share on other sites More sharing options...
Patt Posted February 12 Report Share Posted February 12 throttle body added bhp and torques over the whole rev range on my old 986 (AKA Molly on the owners thread). It literally woke up the throttle response from "wait for it" to ALIVE. I did lose 1-2 mpg, but a must mod for me as it was cheap and I didn't do a re-map. Plots should be in the Molly thread, the how to is in EDC's thread as we fitted his first. 1 Quote Link to comment Share on other sites More sharing options...

I have searched Molly with no luck and cannot find an owners thread? Cheers Quote Link to comment Share on other sites More sharing options...
Patt Posted February 13 Report Share Posted February 13 Have to say, that took me a bit - the search engine couldn't find it ! 1 Quote Link to comment Share on other sites More sharing options...

Hi @Patt I have read through all 11 pages and although there is reference to a larger tb and plenum I could not find any description of the work or dyno graphs other than a note that power had gone from 202 to 254, which makes me think maybe there was a problem that was then resolved. No notes about increased power due to mod though? Maybe in another thread? Quote Link to comment Share on other sites More sharing options...
Patt Posted February 14 Report Share Posted February 14 I'll have a hunt to see if I have the plots. The total power gain was purely good servicing (new coil backs, plugs oil etc.)and the TB + a panel air filter. From memory the TB gave 3bhp and 6 lbft over the whole range, but the improvement in driving was way more noticeable than the numbers suggested. And it only cost about £120 to do! 1 Quote Link to comment Share on other sites More sharing options...

What TB and where would one obtain it ? What other parts are required? If you don’t mind me asking….. I have the airbox, (that’s a start!

Nitro V8 Posted February 14 Report Share Posted February 14 (edited) I have a generic Bosch 74mm tb that mates up to a 996/7 plenum/t tube which I also have. Edited February 14 by Nitro V8 Quote Link to comment Share on other sites More sharing options...
edc Posted February 14 Report Share Posted February 14 996 throttle body and plenum. I have spares in my garage if you are looking to do this mod. Quote Link to comment Share on other sites More sharing options...

We spent a few fun Saturdays sorting this out, didn't we Ed. It was only the other week I threw away the "plan A" drainpipe 😆 Quote Link to comment Share on other sites More sharing options...

phazed Posted February 15 Author Report Share Posted February 15 Are those what are required or leftover? Quote Link to comment Share on other sites More sharing options...
Patt Posted February 15 Report Share Posted February 15 That was everything after removal. Same as everything required: 1 x 74mm TB 1 x 996 TB intake pipe (iirc £12 from OPC) 2x 82mm 90 deg hose 1x 80x 300mm ali pipe for intake or intercooler. 6x new hose clamps Cut hose to size + profile required (NOT as easy as it sounds) The one for EDC took a couple of weekends to get right, mine took not much more than an hour, using the EDC as a template.

edc Posted February 15 Report Share Posted February 15 In will my check garage at weekend but 99% sure I have the throttle body and plenum as I was going to do this for my 550 too but gave up a long time ago. Quote Link to comment Share on other sites More sharing options...
