Ellis Posted November 19, 2003 Share Posted November 19, 2003 Given a very small budget, does anyone have any tips on getting the most out of the good old 16v lump ??? ;) Link to comment Share on other sites More sharing options...
Greeks Posted November 20, 2003 Share Posted November 20, 2003 Yeah! Put your foot ALL the way to the floor ... and then keep it there until she blows! (normally about a minute in a sprint engine?) ;D Link to comment Share on other sites More sharing options...

Ellis Posted November 24, 2003 Author Share Posted November 24, 2003 One thing I have found that really improves the performance is allowing a couple of the manifold bolts to fall out.... Driving the car home from it's holiday at Mr & Mrs Nutter Snr's (aka Mum & Dad's), the car was making a noise which I can only describe as "Fhutting" - it kinda sounds like a Putt, but without the "P"... OK, purse your lips like this :K), then blow like this :P.... Kinda like that sound !!!!Anyway, I dare say this isn't improving performance.... Another thing to add to the list of stuff to do !!! ::) Link to comment Share on other sites More sharing options...
rotten herald Posted November 29, 2003 Share Posted November 29, 2003 BEST THING TO DO TO SPRINT ENGINE, THROW IT OUT, MY MATE TERRY WOULD KILL ME FOR SAYING THIS, PUT A SAAB 99 TURBO IN IT Link to comment Share on other sites More sharing options...
Raider Posted November 29, 2003 Share Posted November 29, 2003 Is the Saab turbo engine the one developed from the original Triumph sourced one?Are you saying that you can get one of these to fit and mate up to the TR7 gearbox?What about the wiring etc?Has it been done?

Ellis Posted December 7, 2003 Author Share Posted December 7, 2003 I've actually done a bit of research on this... Although Triumph did the original design, the engine is very different to that of the Sprint. One comment made was the only part the two shared was the valve gapping shims !!! I think it's safe to say anything is possible, but I don't think it's an easy conversion and the other thing being is where to put the turbo... The Saab 99 & 900 had rather bigger engine bays than the TR7. Nice thought though, a turbo charged TR7... ;D Link to comment Share on other sites More sharing options...
Raider Posted December 7, 2003 Share Posted December 7, 2003 What about a supercharger? Is it still possible to buy them sort of "off the shelf"?I would point out my enquiry is only academic before anyone tries to tempt me! :o Link to comment Share on other sites More sharing options...
Deleted User Posted December 7, 2003 Share Posted December 7, 2003 you need 4 lt V8 s you really DO ,space framed tvr running gear..... Tuning the sprint..small budget? hmmm decent exhuast,electronic ignigtion,just so you dont loose out when the points eat themselves every 2,000 miles,go for a slightly bigger Needle and Jet coupled with some ram pipes on the SU s or go for twin 40s,then go for wilder cam etc Link to comment Share on other sites More sharing options...
Ellis Posted December 7, 2003 Author Share Posted December 7, 2003 OK.... cheers Andy... at least I'm going the right route.... Tubular manifold and sports exhaust already on, K&Ns (need the ram pipes though) - Needles have been changed, but may need even more as when Dale was tuning it, he had to leave it running slightly rich to compensate. I've got a fast road cam, but I'm not sure what spec it is and how it will affect the running of the car. I've always thought they tended to make the car run a bit rough. Any thoughts ???

Deleted User Posted December 7, 2003 Share Posted December 7, 2003 Tuning any engine the general rules apply,make it more efficient,get more air and fuel in!once you have got it in you have to get the burnt stuff out!So exhaust wise you are ok,apart from putting different exhaust valves in,porting the head etc which is way out of budget,same applies to the inlet,but you have got a different profile of cam,If it is a fairly mild one I am guessing only the inlet duration has been changed ie the inlets stay open longer thus to take advantage of this you want to get some more fuel air mix in,thus try a larger Jet needle set up.look on the 2.5/2000 thread Nigel posted up a web site that helps you find a starting point in the mods and tweeks disscusion,then take it to a rolling road,but before get everything you have got, working bang on,the timing should be advanced as you can safley go without pinking, a mildly tuned engine would be around 10 degrees BTDC?dont worry about the tickover being around 1,000rpm with a modified cam.Ram pipes are for fine tuning but do help as the way they affect the flow of air into the carb,longer pipes=more torque,shorter pipes help achive higer rpmAll these tips on general performace tweeking are in one of my weber books which you are more than welcome to borrow,As for being a bit rough,well it will get a bit more peaky the further you modify the cam profile and overlap timing etc but work out where in the rev range you drive the car most and go for a set up that delivers peak POWER not Bhp at that point,and you should have something you can live with,the Bus kicks out peak power around 3,000 rpm which suits me but it isnt as "quick" as some with the same BHP output! its all part of the fun of tweeking! Have fun !! Link to comment Share on other sites More sharing options...
Ellis Posted December 8, 2003 Author Share Posted December 8, 2003 Thanks mate - really helpful advice. I'm gonna have to look into this cam. It's apparently quite a rare one. The guy I got the engine from originally (v8 Stag power power Dolly) was going to town on it, but then decided to do the v8 route instead. I've got an inlet manifold that has been modified to take 2" SUs - that could be fun !!! It's like you say, it's trying to find that balance, I don't want to end up with a car that's undrivable... still could be fun trying to find the balance. I'll be needing to put a roll bar in next !!! ;D Link to comment Share on other sites More sharing options...
Deleted User Posted December 8, 2003 Share Posted December 8, 2003 Wasnt fuel injection tried out on the Sprint engine? for the single seaters the engine used to power-the single seater Mansell drove? Link to comment Share on other sites More sharing options...
Ellis Posted December 8, 2003 Author Share Posted December 8, 2003 I suppose in theory it couldn't be a lot different to the setup in the 2.5Pi ??? Twin SU to Pi conversion, but would a decent carb set up be better... :-/ Link to comment Share on other sites More sharing options...

Ellis Posted December 8, 2003 Author Share Posted December 8, 2003 Oh dear.... maybe I will just stick with the carbs.... seriously though, do you reckon it's worth trying the fast road cam and the other inlet manifold with 2" SUs (I can get some cheap !!).

rotten herald Posted December 11, 2003 Share Posted December 11, 2003 sorry, back to saab turbo again, yes it does fit developed in conjunction with saab, and contary to popular belief it was saab who buit first prototype engine , and works well. Terry vanderzee old me to do it if you want reliablity for road use,although he loves the triumph one. haven't sourced a goodone yet though. he did give me the 1850 engine to keep me going for a year until insurance company allows it. Terry says the block can be used, it redrilling of the studs, unfortunaty dolly sprint racing regs dont allow this but it can be done. the saab engine is a triumph one without the cockups. Terry however is known for mad conversions, after putting engine from etype in a vitesse. as for gearbox will try nd get more out of hm soon. at moment mating toyota 5 speed to v12 jag, so better not distract him, Link to comment Share on other sites More sharing options...
rotten herald Posted December 11, 2003 Share Posted December 11, 2003 actually that reminds me you can fit jag v12 in with some work, while your on throw away body, and replace with ferrari daytona panels from robin hood engineering. Link to comment Share on other sites More sharing options...
rotten herald Posted December 18, 2003 Share Posted December 18, 2003 Its a good conversion,but i suppose its not quite the beloved wedge. what ever mod you do, don't forget to sort the brakes, so nick them of an unloved wedge, the BL Princess/Ambassador, then throw what remains away, however if you get VDP, save interior as leather covers make any triumph that little bit better.

Ellis Posted December 19, 2003 Author Share Posted December 19, 2003 You'll be enjoying my article (hopefully) in the next Club Torque then... all about TR7 brakes and their distinct lack of stopping power...I've got the Capri 2.8i set up on my car, which OK for the purist I know it's not Triumph or even BL, but at least the car stops !! Beats the anchor I used to have to through out the back anyway !!! Link to comment Share on other sites More sharing options...

Ellis Posted December 24, 2003 Author Share Posted December 24, 2003 The discs aren't a problem, you do need spacers (about 1/4") to clear the calipers if you're using 13" rims. Makes a hell of a difference to the brakes though. Link to comment Share on other sites More sharing options...
