huw Posted August 24, 2011 Share Posted August 24, 2011 Hi. got some manta 400 fibre glass bonnet vents and diamond vent. Any body know the dimensions for where they should be set in place on the bonnet. Dont know weather to rivet them on some how or some kind of glue. any ideas would be good . thank you Quote Link to comment Share on other sites More sharing options...
Jason b Posted August 24, 2011 Share Posted August 24, 2011 are you fitting them to a plain fibreglass bonnet, or a standard metal one? Quote Link to comment Share on other sites More sharing options...
huw Posted August 24, 2011 Author Share Posted August 24, 2011 standard metal one. just unsure of the measurements of where they go on the bonnet Quote Link to comment Share on other sites More sharing options...
Jason b Posted August 24, 2011 Share Posted August 24, 2011 ah ok.... if no-one on here has the measurements (I expect several do, though whether they will give them out to a non club member is another matter ) then I can probably measure the vents on mine when I get back after the weekend. The reason I asked was because I have a 400 bonnet but I'm tempted to swap it for a plain fibreglass one (if such items exist) - and I am potentially driving past gwent tomorrow night. Good luck Jason Quote Link to comment Share on other sites More sharing options...
huw Posted August 24, 2011 Author Share Posted August 24, 2011 metal sorry. that would be a great help if you could measure up yours. thank you. theres no rush on it. ive been working it for about 4 years lol Quote Link to comment Share on other sites More sharing options...
monzta Posted August 25, 2011 Share Posted August 25, 2011 (edited) metal sorry. that would be a great help if you could measure up yours. thank you. theres no rush on it. ive been working it for about 4 years lol If you open your original metal hood and look underneath you can actually see where they are supposed to go as the frame has holes at those locations The diamond one is to let heat from the radiator out of the engine bay, and the two sidewents are for intake and the other is to cool down the exhaust (16V 400 engine) Edited August 25, 2011 by monzta Quote Link to comment Share on other sites More sharing options...
spewy555 Posted August 25, 2011 Share Posted August 25, 2011 I have to disagree! The two raises ar to allow clearance for the long travel suspension turrets! 1 Quote Link to comment Share on other sites More sharing options...
huw Posted August 25, 2011 Author Share Posted August 25, 2011 The holes underneath the bonnet sounds promissing. Thanks for that info. Ill have a look on the weekend. Ill also find some 400 pics and try scale it up. Its only for looks anyway so doesnt really matter if its wrong. Quote Link to comment Share on other sites More sharing options...
monzta Posted August 25, 2011 Share Posted August 25, 2011 I have to disagree! The two raises ar to allow clearance for the long travel suspension turrets! I have to disagree as well Those turrets are not original i400 parts, and that was not the reason they were made. Quote Link to comment Share on other sites More sharing options...
spewy555 Posted August 25, 2011 Share Posted August 25, 2011 Thats an artists drawing to show some of the differences between the road and rally homologation. You need to check the FISA homologation papers. Nice try though! Quote Link to comment Share on other sites More sharing options...
monzta Posted August 26, 2011 Share Posted August 26, 2011 Thats an artists drawing to show some of the differences between the road and rally homologation. You need to check the FISA homologation papers. Nice try though! OMG The following pic is from an article in a car magazine making a review of the car in 1981 Do you need more pics of original i400 that has got normal Manta shocks ? Look, homologation papers tell you what is generally allowed on a specific car, as well as descriping the original car in detail. The i400 did never roll out of the factory looking like that, but it is possible it is a mod that has been added later and approved by FIA (FISA). The A series Mantas homologation papers show the car with a cross flow head 8V that i have never ever seen. That does not indicate that all A series look like that, it is just indicating that this mod is allowed by FIA ! Now, let´s be honest shall we? I don´t know for sure what those wents are for, i assumed that having them placed above the exhaust, and above the intake it would give the car some fresh and much needed cool air to the engine room. BUT if as you say these turrets are in the FIA papers, this could also indicate that Opel actually knew that some would mount theese and made the intakes to accomodate this mod. But that is most unlikely. Why make them as intakes, if all that was needed was a small bump ? Doesnt make sense. Anyway, i am out of this discussion before things get out of hand, the i400 never rolled out of the factory with those turrets, that is a fact.

ascona400r Posted August 26, 2011 Share Posted August 26, 2011 Maybe the vents were made for both air flow and raised turrets in mind..... Would a standard steel 400 hood close with the raised turrets in place ???? Quote Link to comment Share on other sites More sharing options...
spewy555 Posted August 26, 2011 Share Posted August 26, 2011 (edited) Cheers Brian..at least you get it. I think you are missing the point my friend, the fact that the road cars and some of the tarmac spec cars did not use the extended turrets is totally irrelevant, the raises in the bonnet were homologated specificaly for the turret clearence. I`ve been rallying the 400 for more years than I care to remember and have had the pleasure to deal with a lot of the guys who were originaly involved with the cars homologation and subsequent development, hence the spec of my current rally car. Sorry. Edited August 26, 2011 by spewy555 Quote Link to comment Share on other sites More sharing options...
monzta Posted August 26, 2011 Share Posted August 26, 2011 That´s amazing, I bow my head, and accept i was wrong then. I have never seen those turrets before, first i figured they where home made or something. We have no genuine 400´s racing here, and the replicas that do race (hillclimb, rally and track) doesnt have them. Quote Link to comment Share on other sites More sharing options...

spewy555 Posted August 28, 2011 Share Posted August 28, 2011 Looks like you may have to! Here you go, this is using the extended turrets, 1 Quote Link to comment Share on other sites More sharing options...
